I am pretty new to Splunk. Guess what, the consultant has left and I was supposed to take care of Splunk. I got an alert saying "indexer is not reachable". I can ssh to the server, the CPU and disk are OK.
What else can I check?

It can be of different reasons but do the basic checks
Check if splunk process is running on indexer. Switch to your splunk user on indexer and change the directory to $SPLUK_HOME/bin where SPLUNK_HOME is the directory where your splunk installed and run
./splunk status.Check if the indexer is accessible from search head on port 8089 (or the management port you used)
Check if the firewall is open between search head and indexer if they are not on the same subnet.

It says it is running ok:
./splunk status
splunkd is running (PID: 3001).
splunk helpers are running (PIDs: 3002 3018 3089 3188 3294 17563 17713).
I also test the connection and it is OK. I also didn't see obvious errors from log files.

run a search | eventcount summarize=false index=* index=_*|table server|dedup server and see if all of your indexers are listed under server. It might be a momentary n/w issue. Are you still getting the error?

A server reboot solved the issue, still don't understand why.
Thanks for the help!
