After renaming an app Splunk logs shows the old app name

Environment

PCF 1.11  -  Splunk Firehose Nozzle v1.0.0 - Splunk endpoint

Symptom

After renaming an app with command "cf rename", Splunk logs still show the old app name.

Cause 

There is a parameter to tweak this behavior called “APP_CACHE_INVALIDATE_TTL” in the Splunk Firehose nozzle app. By default, this parameter is set to "0s", which means the nozzle will not update the cache once deployed. 

Resolution

Update the "APP_CACHE_INVALIDATE_TTL" value (ex: 60s, 60m) in the Splunk Firehose nozzle app and redeploy the app.

Note: If there is a large number of apps in the environment, use a higher TTL value to balance the increase in load.
