Splunk Command Modular Input v1.5.8

by www.baboonbones.com

May 2022


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.


This is a Splunk Modular Input for executing commands and indexing the output.

It is quite simply just a wrapper around whatever system commands/programs that you want to periodically execute and capture the output from ie: (top, ps, iostat, tshark, tcpdump etc...). It will work on all supported Splunk platforms.



Activation Key

You require an activation key to use this App. Visit http://www.baboonbones.com/#activation to obtain a non-expiring key

Custom Output Handlers

You can provide your own custom Output Handler. This is a Python class that you should add to the command_ta/bin/outputhandlers.py module.

You can then declare this class name and any parameters in the Command Input setup page.

Encryption of credentials

If you require an encrypted credential in your configuration , then you can enter it on the setup page.

Then in your configration stanza refer to it in the format {encrypted:somekey}

Where somekey is any value you choose to enter on the setup page to refer to your credential.

Streaming vs Non Streaming Command Output

Some commands will keep STD OUT open and stream results.For these scenarios ensure you check the "streaming output" option on the setup page.

Environment variables

Environnment variables in the format $VARIABLE$ can be included in the command name and command arguments and they will be dynamically substituted ie: $SPLUNK_HOME$


Modular Input logs will get written to $SPLUNK_HOME/var/log/splunk/commandmodinput_app_modularinput.log

Setup logs will get written to $SPLUNK_HOME/var/log/splunk/commandmodinput_app_setuphandler.log

These logs are rotated daily with a backup limit of 5.

The Modular Input logging level can be specified in the input stanza you setup. The default level is INFO.

You can search for these log sources in the _internal index or browse to the Logs menu item on the App's navigation bar.
