Data generated from the app is being forwarded with index = "os" but that doesn't exist on our corporate splunk instance. I edited indexes.conf, replacing "os" with the name of my index, and when that didn't work, I edited inputs.conf and added index = "myIndex", but the data still shows up with index = "os".
Here's what the files look like now.
$ cat ~/etc/apps/Splunk_TA_nix/default/indexes.conf
# Copyright (C) 2005-2016 Splunk Inc. All Rights Reserved.
homePath = $SPLUNK_DB/os/db
coldPath = $SPLUNK_DB/os/colddb
thawedPath = $SPLUNK_DB/os/thaweddb
To correctly address Your inputs, you have to insert index=my_Index in every room of inputs.conf.
In addition, you displayed inputs.conf of local folder, probably there are other rooms in default inputs.conf.
In this case copy these rooms in Local inputs.conf.
