MQTT Modular Input

Overview
Details
This is a Splunk Modular Input Add-On for indexing messages from a MQTT Broker.

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 installing in your own hosted Splunk Enterprise environments or on your own hosted Splunk Forwarders and forwarding the collected data into Splunk Cloud.

If you want to install this App directly in Splunk Cloud , for our Commercially supported customers on our Ultra plan ( https://www.baboonbones.com/#support ) we provide custom private builds of any of our Apps tailored to the customer's specific requirements and configuration , and these custom private builds can then be uploaded as your own private Splunk Cloud Apps.

For customers that don't have support, we also offer the option to perform ad-hoc custom private builds of any of our Apps.

Browse to https://www.baboonbones.com/#cloud for more details of our Cloud options and offerings.

Version 1.7.5
April 3, 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 the MQTT Modular Input , we had to change the way that mqtt.py invokes it's child java process. 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.
