Custom conf files replication in search head cluster

[VatsalJagani]

I've one App which has Add-on builder created configuration page with API key, proxy settings, etc. This configuration is going to store in _settings.conf in local.

If I configure this on one of the search head, will this configuration replicates to other search heads?
If Yes - Any document that can say that custom conf files replicates to other search heads.
If No - How should I configure App?

Yes custom configuration files will be replicated, within some boundaries..

PLease read this doc file : https://docs.splunk.com/Documentation/Splunk/7.2.6/DistSearch/HowconfrepoworksinSHC

This outlines what is replicated, and what triggers that replication.

@esix_splunk - I want to add here that, if Addon/App is making all conf changes through RestAPI then only it will replicate, if it is making change with ConfParser then it will not replicate.

Note this, as stated in the docs..

The cluster replicates changes made through these methods:

Splunk Web
The Splunk CLI
The REST API

So yes, using a custom python command to modify configurations will not trigger a configuration update. If you're editing this way, it would be better to finalize the script with a hit against the rest config endpoint for the app....
