Protocol Data Inputs

The ORIGINAL Data Stream Processing Solution for Splunk and still going strong !

This is a Splunk Add-On for receiving data via a number of different data protocols such as TCP , TCP(s) ,HTTP(s) PUT/POST/File Upload , UDP , Websockets , SockJS. The event driven , non blocking , asynchronous architecture is designed to handle connections and data at scale. The polyglot event bus allows you to declaratively plug in custom data handlers in numerous different languages(Java , Javascript , Python, Groovy , Scala , Clojure , Ruby etc..) to pre-process raw data before indexing in Splunk. Secure transport channels also allow for client certificate authentication.

The Python code in this App is dual 2.7/3 compatible.
This version of the App enforces Python 3 for execution of the modular input script when running on Splunk 8+ in order to satisfy Splunkbase AppInspect requirements.
If running this App on Splunk versions prior to 8 , then Python 2.7 will get executed.

For details of the support we offer for our Apps , browse to : https://www.baboonbones.com/#support

This App is fully AppInspect passed for running in your own Splunk Enterprise environments or running on your own Forwarders and sending the data into Splunk Cloud.

Release Notes

Version 1.9.7
June 18, 2022
  • in order to support huge modular input configuration xml strings when users want to run a very large number of inputs on 1 single instance of this app , we had to change the way that the child java process is invoked. Previously the xml string was passed as a program argument which could break the max argument size in the Linux kernel. Now we changed the logic to pass the xml string to the java process via the STDIN pipe.

  • The app performs periodic socket pings to the splunkd management port to determine if splunkd is still alive and if splunkd is not responding , usually because it has exited or is not network reachable, then the app self exits it's running java process.The default timeout is now 300 seconds. You can change this timeout value in bin/protocol.py by setting the SPLUNKD_TIMEOUT_SECS variable.

Docs updated
Splunk 7.1 compatible

Version 1.3
Nov. 17, 2016

Added the latest jython jar to the main classpath because the jython language module that
is dynamically installed is missing some useful jython modules ie:json

Version 1.2
July 28, 2016

Added an example handler for decompressing gzip content

Version 1.1
Nov. 24, 2015

Minor HEC data handling tweaks

Version 1.0
Sept. 22, 2015

Added support to optional output to Splunk via a HEC (HTTP Event Collector) endpoint

Version 0.7
Feb. 11, 2015

Enabled TLS1.2 support by default.
Made the core Modular Input Framework compatible with latest Splunk Java SDK
Please use a Java Runtime version 7+
If you need to use SSLv3 , you can turn this on in bin/protocol.py


Version 0.6
Nov. 15, 2014

Abstracted the output transport logic out into verticles.
So you can choose from STDOUT (default for Modular Inputs) or bypass this and output
data to Splunk over other transports ie: TCP.
This also makes it easy to add other output transports in the future.
Futhermore , this makes the implementation of custom data handlers much cleaner as you don't have
worry out output transport logic or formatting Modular Input Stream XML for STDOUT transports.

Version 0.5.1
Nov. 11, 2014

Added langs.properties and repos.txt to the classpath

Version 0.5
Nov. 10, 2014

Initial beta release
