A thermal monocular offers several benefits, some of which you may not initially consider. After having used a thermal monocular
for over 2 years, I’d like to share some of the ways I use it to get an edge in the field and some ways you may
not have thought about using a thermal monocular before.
A thermal monocular offers several benefits some of which may not initially obvious. After having used a thermal monocular
for over 2 years, I’d like to share some of the ways I use this recent technology to get an edge in the field and
beyond and some ways you may not have thought about using a thermal monocular before.
As a hunter, I am always looking for ways to gain an edge. It didn’t take me long to appreciate the benefits gained
from using a thermal monocular. I primarily hunt deer, hogs, coyotes, and turkey. Finding ways to use a thermal monocular
to gain an edge hunting each of these species was easy. Let’s get to it…
No More Spooking Deer on My Way In or Out of the Deerstand
One of the first benefits I realized a thermal monocular brought was that it provides me the ability to enter and exit
the woods without spooking any deer. That is, when I start out to my stand I scan with my monocular. When approaching
the stand if I see any deer on the corn pile I simply stop and lean on a tree or sit on the ground until they leave.
Without this ability to see into the dark I wouldn’t have a clue that deer were anywhere around, and I’d
be climbing in my stand only to hear the deer blowing and running off – that doesn’t happen to me anymore.
Likewise, when the sun sets, I always scan before exiting the stand. There have been plenty nights where I sat in the
dark for 10 or 15 minutes until a deer exited my area. Deer are no longer aware of my location simply because I was making
noise in the dark and didn’t know they were close by. This is solely because of the thermal monocular giving me
vision where I previously didn’t have it.
Track Deer More Efficiently
The thermal monocular also comes in very handy when trailing or tracking a deer. If you’ve ever shot a deer right
at dark, you know that it can sometimes be challenging to track them. If you made a good shot, then the thermal monocular
will likely save you some time. Yes, you should get on the blood trail as you normally would, but also use the thermal
monocular to scan the general direction the deer ran in and you may be surprised at how much more efficient your tracking
becomes. I’ve got friends who call me to come help them track deer simply because they know I’ve got a thermal
Locate Turkeys on the Roost More Easily
Turkey hunting is also one of my favorite things to do. There’s nothing better than watching a big gobbler strut
and there’s nothing more depressing than not being able to locate any birds. If you know the general area where
turkeys are roosting, then a thermal monocular may provide you with an edge in this scenario as well. Now days I always
take the thermal monocular with me when we go in before dark. I scan the tree tops to see if I can see any turkeys roosting.
Admittedly, turkeys are a little more difficult to pinpoint because their heads are usually the only part that shows
a sharply contrasting heat signature and during the spring the trees provide them with more cover. Though, the thermal monocular still
provides the opportunity to spot them. This again gives me an edge and as you would imagine we take it and use it as
much as possible. Locating birds is half the battle and a thermal monocular can help you locate them more easily.
Our Primary Use – Scanning for Hogs & Coyotes
The most obvious time when we use the thermal monocular is for coyote and hog hunting at night. We set our guns on tripods
and use the monocular for scanning and locating. As soon as we locate then the game we get into the scopes. If you don’t
have a scanning monocular you will quickly learn that it saves your back big time because you don’t have to constantly
be hunched over scanning in circles in the scope. Also, the monocular is safer to scan with. That is, if we are spinning
circles with our guns, we are pointing the guns in all directions which inevitably become close to other hunters and that’s
not a good thing. Since the monocular is obviously not attached to a gun it’s the safest route for detecting game.

Easily Locate Rabbits
For you rabbit hunters, I know it’s all about the dogs but if you want to easily see rabbits that are hiding in
the edge of briar patches there’s no better way than with a thermal monocular. We constantly see rabbits in the
edge of brush, in straw, and alongside fields while hog and coyote hunting. Want to get your dogs pointed in the right
direction… try a thermal monocular.
Something I noticed while looking at all kinds of things with my thermal monocular is that I can use it for surveillance
if needed. If a group of cars is parked around a house, I can easily tell which cars have been there the longest (they
are cooler) and which ones have just arrived (they are hotter). If you ever have out-of-place individuals lurking in
the shadows they are easily picked out with a thermal monocular. There’s not much hide and seek when it comes to
thermal technologies. The only area this isn’t 100% effective is in scenarios where there are windows. Thermal
detection doesn’t work through glass, other than that it’s awesome to use to see into the night and get whatever
info or recon you need.
One of my friends is a home inspector. Sometimes he’s looking for locations where hot or cool air may be escaping
a house. A thermal monocular is a great tool for this type of scenario.
Imagine an HVAC system that wasn’t installed correctly or if a pipe was leaking. A thermal monocular is a great tool
in these scenarios. Also, one can easily spot the hottest or coldest parts of any machine that could be “running
hot”. Wherever temperature matters a thermal monocular could potentially be useful.
Wondering which device you should use is a common question. After all, these devices are not cheap and as such these are
decisions that shouldn’t be made lightly. Since the purpose of this blog is to provide insight into ways one can
use a thermal monocular, I’m not going to compare all the options out there. A simple Google search will show you
the brand leaders and products on the market.
I’ll simply say that I am on the Pulsar Pro-Staff and I use
Pulsar products. I’m a fan of the
Pulsar Helion XP-50 and it’s what we use on all our hunts. Pulsar recently announced the “Axion” line of monoculars as well. I encourage you to do research and go with the device and manufacturer that
is the best tool for your job.

We are excited to announce that two of our WeHuntSC.com members are now Pulsar Pro-Staff members. Adam Smith and I were recently selected to the Pro-Staff team and we are excited to see what 2019 has in store. As you may have seen in our posts, our team has been doing a lot of night hunting lately and we use Pulsar scopes on our setups. We’ve been putting a lot of time into the images and videos we share from the hunts and Pulsar has recognized.
Adam and I look forward to learning more about Pulsar’s vision for the future of night hunting, thermal optics, and to learning more about Pulsar products. If you are interested in Pulsar’s products and/or want to know more about our setups feel free to reach out.
Recently I presented on one of Microsoft’s latest technologies, Blazor, at our Southern Fried DNN User Group meeting. DNN, like many ASP.NET web applications, is looking for ways to get more modern and I believe that Blazor and Razor Components could play a big role in DNN’s journey to .NET Core. In this meeting I presented an introductory level session on Blazor.
Topics reviewed were the What, Why, & How followed by demos of each Blazor project type... client-side, ASP.NET Core hosted, & Server-Side. We looked at components, routing, parameters, parent-child components, and dependency injection throughout the demos. The group, which was in-person and online, consisted of some highly skilled developers in the DNN Community, DNN integrators, one of the DNN Co-Founders, and the former VP of Product at DNN. Everyone was intrigued by Blazor and we had some good dialog and conversation around the future. We are all excited to see where this goes!
I need to start out by saying that I’ve been inspired to do all this by some great guys in the Charlotte area and they are Dan Thyer, Mike Linnen, and Jay Ziobrowski… thanks for the motivation guys! I am either copying something creative I’ve seen them do or trying to imitate their passion, talent, and drive for Halloween and/or IOT projects. One day I hope to be as sharp and creative as they are.
Halloween & IOT
In 2016 I made a flame throwing pumpkin (copy-catting one of Dan’s inventions) and let’s just say some of the parents weren’t too keen on fire being near their kids and I also didn’t make any fans on the community’s HOA! Though, we all must start somewhere. In 2017 I went the safer route and made the AirGhost which is very similar to this year’s project.
The IOT Clown
This year I have created an IOT Clown. I did some testing and iterating on various ideas and concepts and there’s just no way to get around it… the thrust of compressed air brings a startling surprise and the best part is that it’s safe. We have tons of young kids in our neighborhood and moving a skeleton bone (which I debated in this early prototype) could likely hit someone, cause a toddler to fall, or trip someone up which could potentially lead to a spill on the concrete sidewalk. I don’t want to injure anyone or have some local parents mad at me, so I reverted to the compressed air, but then added a few more movements and changed the medium from a ghost to a clown.
Here’s a quick video of the end-product prototype just to show you where we’re heading… I’m going to dress it up a little more by Halloween, but you’ll get the gist.
Here are the main components I’m using for this project:
Here’s a video “talk-through” of the mechanical parts and power supplies being used.
Let’s Talk About Particle
The Particle platform is awesome! Check out this video of the Particle platform to learn more. I am admittedly a little bit behind all of Particle’s new innovations. I still need to learn about their Mesh and Argon solutions. Even though I’m not 100% up to speed I know you can do tons of creative stuff with the particle platform, their multiple IOT devices, and their integrated IDE. Since I’m using the Particle photon, we’ll start with it.
The Particle photon is a small IOT (internet of things) device that makes it easy to bring real world objects online. Particle makes it easy to setup the device and to connect to Wifi via a mobile app. If you want to know more about initially connecting and getting up and running with Particle they have some of the best documentation I’ve seen check out the doc, tutorials, and guides.
For this project all I really want to do is to move 3 servos… one for the head to spin, one for the head to roll, and one to push the handle on the air compressor. To do that we need to use the components I listed above + Particle’s platform + some code. I’ve listed out the components and just introduced the photon… now let’s look at some code.
Let’s Look at Some Code!
Particle’s platform is awesome, but we need some code to make things happen! I could easily copy and paste code here, but that wouldn’t help you understand the “why” and “how” behind some of the concepts. I hope to help you connect some dots here and as such I’ve cut a video walking through how I’m doing some of this stuff. The video shows code and includes videos of the device in action.
To all you senior devs… yes, the code shown in the video could be much better. I have not refactored anything yet, so the code is not nearly as efficient as it could be. And yes, I showed my handy Particle access token in the video… no worries though, by the time you read this I’ve already recycled it and created a new one.
Here are some relevant links:
So, with some disclaimers down and links shared let’s talk through the code some…
If you take the sum of all the info presented here that is how I’m making this happen!
And We Wait on Halloween!
Halloween is just about a week away at this point. If you have any questions or issues filling the gaps in this high-level tutorial, please reach out and ask your question. I plan on trying to video some of the fun at Halloween and posting any interesting reactions here just below this section… so stay tuned!

As an open source enthusiast and a .NET developer I’ve been watching the transformation of Microsoft happen and it has been great to watch. You see I’m an avid user of DotNetNuke and if you know anything about DNN’s history you know that DNN was one of the earliest, if not the earliest, open source project in the .NET Ecosystem. From 2003 on DNN has been a pioneer in the .NET open source world.
A lot has happened and several trends have come and gone in the Microsoft world since 2003. As an open source project built on Microsoft technology the notion of being open source wasn’t always a popular conversation topic. Being open source wasn’t “cool” and sometimes negative perceptions about open source solutions were visible.
Boy have times changed!
Microsoft is Serious About Open Source… and It’s Not Just Lip Service
One of my college football coaches always said “Your words don’t mean anything, but your actions mean everything.” Actions are a really good sign of what someone really believes.
Microsoft’s strategic shift to embracing and focusing on open source over the past few years has been such a refreshing transition to see, feel, and experience for me and my fellow DNN’ers because of the actions we are seeing.
If we look at the recent and strategic moves Microsoft has made it’s easy to see that Microsoft is indeed serious about open source. If you aren’t convinced that Microsoft is serious about open source or if you are not keeping up, let’s look at some of the actions Microsoft has taken related to open source. And these are just the ones I have observed… I’m sure there is even more evidence out there.
Why It’s a Great Time to Be a .NET Developer
There has never been a better time to be a .NET Developer. Literally everything you need to get started building is online and free to use and even better it’s likely open source. Anybody, anywhere can download code, look at it, enhance it, modify it, and submit it back to the projects if desired. If you can dream it, you can build it and you may build an online team of users and contributors to assist you in the process. Microsoft is literally making it easy to build open source projects via the technologies and resources they are providing. They are removing roadblocks for developers and being 100% transparent.
Consider the following capabilities anybody, anywhere has...
I referenced one of my college football coaches earlier, but he wasn’t the only one to to impart wisdom during my athletic days. My high school coaches had more one-liners than anyone could remember. One line that stuck with me was “If you do the little things, the big things will take care of themselves.” Microsoft is not only doing the big things, but they are also doing the little things that continue to reinforce their seriousness about open source.
We are watching a culture and paradigm shift occur in real-time and it’s awesome. By going “all in” on open source Microsoft is not only winning the hearts of developers, but they are making it easy for developers to get started with their technologies! I think the strategic decision to embrace open source will have a big impact for Microsoft in the long term.
Last week I attended Microsoft’s Build Conference in Seattle. I was helping at the .NET Open Source booth which promoted the .NET Foundation and all things open source. The conference was very nice, and the energy level was high. I had conversations with a wide variety of people during the conference and it is obvious that Microsoft’s strategy of embracing open source is welcomed by developers.
During one of my discussions a gentleman told me that his organization uses open source software (OSS) and he wants to allow his developers to contribute to OSS, but he needed to be able to justify it to his corporate leadership. His organization is a large, global organization so he needed solid and clear reasoning for why contributing to OSS is something his company should support.
He asked me if I knew of any blogs or resources that could provide insight into this topic. I thought about it and while I’m sure there is info somewhere, I wasn’t aware of any specific blogs or content about this subject. I am obviously biased about this topic, but let’s consider some reasons why a business should support OSS… especially if their organization is using OSS-based products.
Before we list out reasons we should first define what “support” means. When business people hear the term “support” they generally think about money, cost, or financial implications. Though, in the open source world it’s not necessarily about money as support can come in many different forms. Of course, the obvious need for any OSS project is code contribution, but there are more ways to contribute than one may initially think. As examples outside of the code, organizations could allow their developers to assist in marketing and promotions of sub-projects, conferences, user groups, GitHub repos, project documentation etc. Developers could also volunteer in any area of the OSS project as well as exchange knowledge online via forums, blogs, StackOverflow, and others. Organizations could also open up their offices for user group meetings, donate swag & door prizes, or sponsor the food at meetings. Any step taken to help move the the OSS project forward is a form of support.
Now that we know that support can come in forms outside of financial contributions let’s get back to the subject. If you are faced with the need to justify supporting open source software to your business leadership here are some thoughts and ideas to consider:
In this blog I’ve summarized my thoughts around why it’s important for organizations to give back, be active in, and support OSS projects and communities. As one considers justifying OSS participation to the business side of an organization much of the conversation will center around educating the business-side on how OSS ecosystems function. Communicating the potential positive benefits will be what’s needed to help bring on a change in perspective or cultural shift within the organization.
In my mind there are only positives to gain from contributing to OSS projects. Your developers will learn more, be empowered, meet new developers of all ages and skillsets, and your organization will be more efficient, and will likely be viewed as a great organization to work for.
If you don’t want to jump in head first then just try this one small thing to get your feet wet - if your developers have “down time” then simply encourage them focus their energies and time to assisting with the OSS project in any area they choose and watch what happens to your company in the months ahead. Be sure to pay attention to job satisfaction levels, quality of incoming new hires, general passion for work, and the perception of your organization among developers in your space.
After all, have you noticed that OSS projects that thrive are the ones with active community support? Who doesn’t want the project they use to not thrive? From my perspective the benefits of contributing to open source software far outweigh the drawbacks of not contributing.
Last week I attended Microsoft’s Build Conference in Seattle. It was my first time attending so I was excited and didn’t know what to expect. It didn’t take long to realize that Microsoft puts on a top-notch event. From DJ’s playing music during the waiting line, to the constantly available live-stream piped everywhere throughout the event, to “cuddle-corner” where attendees could pet animals and relax, to the awesome expo, and non-stop new features and functionality being rolled out one could easily be impressed.
It was indeed a great event and I’d like to share a few things I learned from having attended the conference. These items will be more high-level and conceptual things I noticed versus down-in-the-weeds technology specific items.
As attendees listened to live-streamed sessions and keynotes the word cloud and “Azure” was prevalent throughout. I spent a lot of time in the expo hall of the event and I must have walked around it 6 or 7 times looking and booths and talking with Microsoft staff. Each booth has a navy-blue sign with white letters at the top indicating the technology being demonstrated at the booth. It was very eye-opening how many of the booths started with the word “Azure”. Sure, Azure has been out for a while now and that’s nothing new. I’m just communicating that walking around the expo and listening to sessions and keynotes it is crystal clear that Azure is a major component of many Microsoft technologies.
Take Home Point: If you are reading this and are hesitant to embrace Azure, you should re-think your position, or you’ll soon be left in the dust.
At the event Microsoft released “Sphere” which is a solution for creating highly-secure connected microcontrollers (IOT devices). And you guessed it… they connect to Azure! Many of the highly attended sessions and one of the most highly-trafficked booths all centered around Sphere.
As an IOT hobbyist I spent some time at the Sphere booth asking all kinds of questions about the Sphere Development Kits. I think the devices will be high-powered and offer a lot of functionality, but right now the price-point seems high in comparison to competitor solutions and the device that was being demo’d only connects to wi-fi currently. I imagine in the future they will connect to cellular via a SIM as well. One could argue that the increase in cost is the tradeoff for security as Microsoft touted how secure these devices are.
While micro-controller devices were being demo’d it’s important to note that Microsoft is not making the micro-controllers, rather they are working with established vendors in the industry to do so. Microsoft is collaborating in the design of the devices and helping align them with their IOT strategy for the future.
Take Home Point: Microsoft is continuing to invest in IOT, is linking devices to Azure, and is promoting the security of their IOT solution.
Another common thread throughout the event were the words “ML” and “AI”. You could hear this being presented in several sessions, keynotes, and there were booths discussing and demoing these topics as well…. and it makes sense. If your overall strategy is the cloud (Azure) and now IOT devices are easily connected to the cloud and sending tons of data to the cloud, then what will you do with all the data? The answer: you will learn from it and use it to make better decisions and become predictive.
An example demo showed a DJI drone flying over the top of a building looking at HVAC pipes analyzing them for inconsistencies or anomalies. Within seconds the drone was able to pick out the pipe that had the issue and show it to the audience in real-time. One can easily see the benefits of equipping the drone with AI capabilities.
But it doesn’t stop there… Microsoft is making it easy for developers to tie into their ML and AI capabilities in Azure. If you’ve got data stored in Azure, chances are leveraging the ML/AI capabilities offered to you by Microsoft could help your organization.
Take Home Point: Don’t write “ML” and “AI” off as just buzzwords. If you are using Azure then you may be surprised at how ML and AI can already help you. Give it a look!
One thing that also stuck out to me at the conference was the energy and level of enthusiasm of attendees and exhibitors. And I’m not just talking about Microsoft fan-boys. There were a lot of non-Microsoft developers at the event which was interesting and served as proof to me that Microsoft is on the right track strategically speaking.
As of late Microsoft has been heavily promoting open source and being open in general. From the open-sourcing of many of their .NET Technologies, to embracing non-Microsoft technologies (think running Linux in Azure) Microsoft is earning the respect of developers. But this stuff doesn’t just happen by luck. Microsoft has taken a different strategic stance and it is paying off… you could easily “feel” it while at the conference.
Take Home Point: This ain’t your granddaddy’s Microsoft!
I’m glad I went to Microsoft Build. I’ve been to several conferences over the years (including South by Southwest) and Build was by far my favorite. Yes, the content was great, but the conference experience extended beyond the content of the sessions and was woven all throughout all touch points of the event.
Everything was well-planned, organized, and first class from what I could tell. The registration process went smoothly, swag was everywhere, food and drinks were easily available, “Flow” of the expo was easy and open, the venue was great, several hotels were close by, the new technologies and content was awesome, and the Microsoftees were friendly. I didn’t see any attendees who had issues connecting to the internet or complaining about the typical things you’d see at conferences. All the details seemed to have been handled.
After all, where else could you hear about the latest and greatest technologies, pet dogs/rabbits/miniature horses, get free massages, meet the leaders of Microsoft, and have bottomless refreshments and snacks all in the same room?
Take Home Point: If you haven’t been to Build, you should go. It’s a great event.
If you keep up with the blog or the SC Hog Removal page you know we’ve been getting calls from local farmers with hog problems. We’ve been staying after these hogs as it seems they can reproduce nearly as fast as we can get them off a farmer’s property. It’s a full-time job to keep them at bay and we are having fun with it.
Big & J Hog Attractants
We have been using the Big & J hog attractants “Hogs Hammer It” and “Pigs Dig It” in combination with corn and I can tell you that the hogs do like it! When they come in they stay until all the corn is gone and leave the place looking like a tractor had plowed through it. Here again leading up to this hunt we’d put out the corn and attractants and hoped things would line up.
Labor Day Weekend
I had to hang around for a day or so this Labor Day weekend and so why not see if the hogs were moving I thought. It was also the first day of deer hunting season in my game zone so I went deer hunting before dark, got some food afterwards and then headed out for hogs.
As it was a holiday weekend some of my hunting partners were unable to go, but at the same time some of my friends were back at home for the holiday. I was able to talk Garth Knight into going hunting with me. I let him know the hogs had been acting oddly lately as far as their feeding schedule so I was not sure what would happen.
A Short Hog Hunt!
Garth and I set up overlooking a field that was not far from a swamp. We’d been getting hogs on camera at all hours of the night. Sometimes they would be solo and sometimes they’d be about 15 of them so I didn’t know what to expect. We got there and got setup around 9:15 or so. I was telling Garth about all the lessons we’d learned with night vision technologies, guns, and the way the hogs had been acting lately.
Every few minutes I checked the bottom of the field looking for heat signatures. We’d been there about 45 minutes when I was telling Garth about how the scope can live-stream hunts to the phone. I got up to turn the Wi-Fi on and as I looked through the scope I saw some bright spots coming through the woods. I told him they were on the way! So we finished streaming the video to the phone and just watched as the hogs approached.
I wanted to give the hogs a few minutes to ensure there were no more coming because sometimes there would be large groups trailing the hogs. So we watched the hogs eating the corn for a few minutes. Nothing seemed to be coming behind these hogs so I decided it was time to take action. I asked Garth if he wanted to shoot and he said he’d hold off this time. It took me a little bit to pick out which hog was bigger and I flipped into black hot mode once to see if that would help. Finally, I was able to figure out the hog on the left was the bigger hog and I told Garth to get ready.
A few seconds later, thanks to the Anderson Rifles AM-10 308 Hunter + Pulsar Trail XP 50, the bigger hog was on the ground! Not bad for the first day of deer hunting season right ??
I’ve recently been researching Splunk and have been impressed with its power, flexibility, and ease of use. This blog is not intended to be a step-by-step tutorial, but rather is aimed to show some initial findings, overview one way to integrate Splunk with DNN, and paint the picture of some potential use cases.
So What is Splunk?
If you don’t already know what Splunk is, Splunk is a software company based in San Francisco that produces software for searching, monitoring, and analyzing machine generated big data via a web style interface. Splunk’s software helps organizations with operational intelligence, log management, application management, enterprise security and compliance.
Installing Splunk was simple and after clicking around a little while it was evident that Splunk is an intuitive software. From a UI standpoint, it makes logical sense and the flow is easy to understand. And it didn’t take long to see and understand how powerful it is.
As you may imagine, I began to wonder if and how I could integrate Splunk with DNN.
DNN + Splunk: One Way to Connect the Two
One of Splunk’s powerful features is that it can literally suck in all types, styles, and formats of data. This data can be machine data, log files, or even data from a REST API. There are several mechanisms for getting data into Splunk, but for this scenario, DNN’s web API implementation makes this an easy fit. On the DNN side, a developer can easily create a custom module using web services to expose any DNN data on an endpoint, which Splunk can then access. If you’d like to go the custom module route, check out my other blog series on module development. However, I did not write a custom module to test the integration.
For my initial investigation into Splunk I chose to use DNN Sharp’s API Endpoint module as it allows easy configuration of end points. Splunk is architected to consume any type of data and then it makes that data extremely easy to search, create visualizations and/or alerts with. These searches, visualizations, and alerts can be very basic or very complex in nature.
Another thing to note is that Splunk is architected to do this at scale and can easily parse enormous amounts of data. For example, every time you drink from a Coca-Cola “Freestyle” machine at a fast food restaurant, the data from your drink selection is logged and Splunk helps analyze the data, denote trends, and sends alerts. So yes, those Coke machines (all across the world) are connected IOT devices and Coke is a Splunk customer. See how Coke is using Splunk in the Splunk Conf 2014 Keynote replay session. Imagine how much data that is on a global scaled --> Splunk is helping Coke make sense of it.
Side note: Check out the blog I wrote on using Particle & Splunk to monitor temperature
So, my first goal was simple: see if I could get data from DNN into Splunk.
Sticking along the thought process of “data logs” I figured why not expose the DNN event log on an endpoint and see what I could make happen. Obviously, the event log may not be the best use case as site administrators can clear logs or processes to automatically clear logs sometimes exist. However, for this initial test it is a good candidate. To get the event log data on an end point I used the DNN Sharp API Endpoint module to make a SQL query on the event log view and return it as JSON.
With the event log now sitting out there as JSON on a DNN end point now all I needed to do was get it into Splunk…
Getting REST Data Into Splunk
The Splunk side of this configuration only took a few minutes to configure and keep in mind I’m no Splunk guru (read, it’s easy!). Splunk is similar to DNN in that it’s extensible. Splunk extensions can be found on the Apps and Ad-Ons sections of the Splunk website. I tell you this because ultimately, I followed a blog by Damien Dallimore on getting REST data into Splunk which used a modular input extension and that was all it took. I simply completed the required fields in the Splunk REST Modular Input as shown below.
I chose to poll the data every 60 seconds. With this information inputted I clicked save and returned to the Data Inputs screen of Splunk and chose my newly created data source.
BOOM! I was seeing DNN event log info in Splunk!
Searching, Visualizations, & Alerts in Splunk
With data in Splunk now I needed to proceed to using Splunk to make sense of the data. Splunk’s searching functionality makes it very easy to search for, well... anything you'd like. I’m not yet knowledgeable enough to fully explain all the capabilities, but what I can easily see is that you can select your data source, click on keywords, add them to the source's search criteria and set your desired timeframe for the search. It’s feels as if you have a Google search bar and all your searches are performed on your data source and intellisense & syntax highlighting for your search are provided too!
Once you have a search returning data you can then create visualizations or alerts. And yes, there are tons of visualizations provided by Splunk. These visualizations can be saved as reports or live as “panels” that reside on dashboards. Dashboards can have as many panels as you want and you can have multiple dashboards if you like. Also, you can easily embed these panels into DNN or any other location by clicking the “convert to HTML” link that each panel has. Being able to display this info anywhere you like is a neat feature. Are your mental light bulbs turning on yet?
So, I created a few visualizations based on event log data that was available. I created a number-based-visualization to show a large number that represented a count of 404 errors, a line graph showing the number of failed logins, and a chart showing the 404’s over time. So, in just minutes Splunk was already helping me understand that I have some issues going on with one of my sites. I believe one reason for the 404's is that I've renamed some pages that I think bots are targeting trying to register. Anyways, I've got work to do... don't judge!
Opening Up Possibilities
Now you may be looking at this and thinking to yourself, yeah this is neat, but I could create a custom module to make something similar to this happen. And you would be correct, but keep in mind the potential use cases, flexibility, and scalability of Splunk in comparison to a custom module. You could easily have all your customers as data sources and create dashboards to help you (and your customers) quickly understand what’s going on with your customer's applications. You could also do data mashups of data from a DNN website/web app, some IOT device out in space, and any other data source you can think of to provide valuable insight. And again, Splunk has no problem doing this with massive amounts of data.
With just a little research into Splunk it didn’t take long to get my mind spinning with all the possibilities within DNN and beyond. Think about your current DNN use cases, requirements of your customers, and the exploding IOT market and you’ll soon see the light.
Here are some ideas I had right off the bat:
As you can see the power and flexibility Splunk provides is really nice. I believe Splunk could be a game-changer especially for those with large amounts of data to parse, anybody in the IOT space, and much more. I hope this blog has provided you with an introductory glimpse into some of the capabilities of Splunk and even got you thinking of potential ways to integrate Splunk into your applications or customer's environments. I am still learning about it and hope you will too. I know that I'm just scratching the surface here in my initial findings.

In the past few years I’ve been getting into IOT. You may have seen tweets or blog about the Tech-Turkey project I’ve been working on or flame throwing pumpkins at Halloween. I’ve learned and used Arduinos, Raspberry Pi’s, and Particle Photons and Electrons. It has been fun to learn more and get into the connected world… the internet of things!
I’ve been keeping ServoCity in business and even recently worked to get a custom PCB created. Every step of the way I’ve been learning different things and realizing just how much more there is to learn. Recently I’ve started learning more about Splunk.
What is Splunk If you don’t already know what Splunk is, Splunk is a software company based in San Francisco that produces software for searching, monitoring, and analyzing machine generated big data via a web style interface. Splunk’s software helps organizations with operational intelligence, log management, application management, enterprise security and compliance.
Side note: In my first exploration into Splunk I wrote a blog about using Splunk with DNN that may interest you.
Particle & SplunkDNN is a web application, but what if I wanted to get data from an IOT device? That’s when we call on Particle. If you’re not familiar with Particle, it makes it really easy to bring real world objects online. Particle is one of my favorite IOT platforms. It makes awesome microcontrollers, provides a nice IDE, has awesome documentation, and a great community. Connecting to Particle’s cloud is straight forward and even southerners can do it! See my presentation at our user group on DNN & Particle.
If you’re not familiar with Splunk, it makes it really easy to pull in data (machine data) and make sense of it. I’m talking about parsing vast amounts of data, creating visualizations and/or alerts and making it simple to understand. Even southerners can use it too!
Both Particle and Splunk are industry leaders and have some really big names behind their companies and as clients of their companies.
So why not bring Particle & Splunk together?
Reading Temperature with ParticleTo use the awesomeness that both solutions bring us we’ll first need to read the temperature and post it to a webservice. Here again, Particle makes this easy. I used a basic temperature reader in a bread board layout for this experiment.
Then, in Particle’s IDE I used the basic tutorial level code to read an analog value and post it to a Particle cloud variable. Cloud variables are accessible via web services. That is, I can make a GET request and parse the JSON object to get the data. Epic.
Now we were cooking with oil! The next step was to get this data into Splunk.
Getting Particle’s RESTful Data Into SplunkGetting RESTful data into Splunk is really straightforward thanks to Splunk’s extensibility. Splunk has an extensions gallery that can be found on the Apps and Ad-Ons sections of the Splunk website. I tell you this because ultimately, I followed a blog by Damien Dallimore on getting REST data into Splunk which used a modular input extension and that was all it took. I simply completed the required fields in the Splunk REST Modular Input as shown below.
After clicking save, the data from my Particle temperature reader was showing up in Splunk!
Creating Dashboards from the Particle DataOnce data shows up in Splunk you can literally perform any search query you want on the data and create/configure dashboards, panels, reports, alerts and more. Splunk is very powerful in this regard and scale to infinity. However, for this scenario I just wanted log the temperature over time from one device, as well as the temperature’s highest, lowest, and average. Splunk, again, made this very simple.
After clicking on the “result” field I created some visualizations and voila! Out popped some neat dashboards showing all my data in a way that’s easy to understand.
If you are like me, you kind of want to see things in action. So for those of you like me who are visual learners, here’s a quick video of the solution in action.
An IOT Combination That’s Hard to Beat!As you can see, both solutions are awesome and the opportunities are endless. Consider the possibilities here… Particle is easy to deploy and post data to the net and Splunk can easily connect, suck in data, and bring instant insights. The more data you give to Splunk the more knowledge you’re going to have. Splunk can handle this at scale too… I mean massive scale. Why not connect thousands of devices and pump all the data into Splunk and tune it to your liking! I believe that’s what they refer to as operational intelligence 😊 Now my mind is spinning with possibilities. Is yours?
