Configuring HAProxy & Splunk With REST API & SDK Compatibility
As a customer of Splunk I used HAProxy as a software load balancer to distribute users amongst my search heads. I was using the old search head pooling technology at the time, but the same principal holds true for our search head clustering feature; both require a load balancer to distribute users to your search heads. At the time, I couldn’t quite get HAProxy configured to allow use of the REST API. I now believe that was a function of the fact that I was on the 1.4.x branch which didn’t support SSL proxying.
Late last year I had a customer who used our professional services to help with a project. It revolved around using our SDK’s and REST API …

New support for authoring modular inputs in Node.js
In this post, I’ll show you how to create a modular input with Node.js that pulls commit data from GitHub into Splunk.
Node.js is designed for I/O intensive workloads. It offers great support for streaming data into and out of a Node application in an asynchronous manner. It also has great support for JSON out of the box. Finally, Node.js has …

This release is a continuation of our commitment to provide developers a rich platform for developing Splunk solutions.
- C# SDK 2.0 – A new, modern, C# SDK for building cross-platform solutions that consume Splunk’s API and/or which extend Splunk.
- Logging libraries – These libraries allow you to easily wire logging in your existing .NET applications to send log data to Splunk via TCP or UDP. It provides .NET Trace Listeners as well as sinks for the Semantic Logging Application Block (SLAB).
- Visual Studio Extension – This extension makes it really easy to get
Recently I had a request internally for how to access the Export endpoint from Splunk from a node.js application. The Export endpoint is useful for exporting large amounts of data efficiently out of Splunk as it will stream the results directly rather than requiring you to continually poll for more results. It turns out we don’t support the Export endpoint currently in our JS SDK, but it is very easy do access it yourself using Mikael’s super simple request module.
A picture (or a snippet in this case) tells a thousand words. Below you can see how to export Splunk’s internal index. Once you start it up it will instantly start streaming. Make sure you have enough disk space, or …
Using Splunk as a data store for developers
A number of years ago, I wrote a blog entry called Everybody Splunk with the Splunk SDK, which succinctly encouraged developers to put data into Splunk for their applications and then search on the indexed data to avoid doing sequential search on unstructured text. Since it’s been a while and I don’t expect people to memorize the dissertations of ancient history (to paraphrase Bob Dylan), I’ve decided to write about the topic again, but this time in more detail with explanations on how to proceed.
Why Splunk as a Data Store?
Some may proclaim that there are many no-sql like data stores out there already, so why use Splunk for an application data store? The answers point to simplicity, …
My experience of building Splunk application
I joined Splunk a couple weeks ago and my first challenge was to learn everything I could about how to build Splunk applications. The best way of doing that is just to write your own application – and this is exactly what I did.
Application which I wrote contains two parts. The first part of application is a very simple scripted input for Firebase, the second part of application is built with the Splunk Web Framework that shows you objects and their routes on Google Maps using both real-time or playback historic information.
I hope that my experience can give you some thoughts about how you can extend Splunk for your needs.…
The Splunk SDK for Python gets modular input support
Support for modular inputs in Splunk 5.0 and later enables you to add new types of inputs to Splunk that are treated as native Splunk inputs.
The latest release of the Splunk SDK for Python brings modular input support. The Splunk SDKs for C# (see Developing Modular Inputs in C#) and Java also have this functionality as of version 184.108.40.206 and 1.2, respectively. The Splunk SDK for Python enables you to use Python to create new modular inputs for Splunk.
The Splunk SDK for Python comes …
Playing with the Splunk C# SDK–from PowerShell
As those who know me know, I Am Not A Developer. I could convincingly play one on TV, but that’s not the point. The point is this: I don’t have a copy of Visual Studio, and I don’t want to! When in Windows, PowerShell is my language of choice (and for good reason). This blog post will show you, in pretty short order, how to take the newly released Splunk SDK for C#, and use it to connect to a Splunk search head or indexer, but doing so from PowerShell instead of C#.
First, let me acknowledge that we do have a very cool Splunk PowerShell Resource Kit that you can download today. It includes over 40 PowerShell-Splunk cmdlets …
