I have a forwarder and an indexer.
I see the app is deployed in the forwarder at location etc/apps/.
Forwarders are up and running.
And log files have data as well.
But still the logs are not coming up on the Splunk search head.
Please guide, where else can I check and how to troubleshoot?
Which app? When you checked the config files, did you look at the forwarder or search head?
Do you have an outputs.conf on your forwarder with indexer information in it to send the data to ?
Try adding your indexer in Setttings/Distributed search/search peers first then monitor (tail -f) both splunkd.log on those servers to check if there are errors in authentication.
