I have a splunk cluster with 3 indexers. I have a non replicated index that for some reason has stopped getting new data on one of the indexers. Other indexes on the same node are getting data. What can I look for to figure out why this index on the one node is not getting new data. The data is coming from a pair of Heavy Forwarders which is my 1st target to check but not sure where to look.
Start with error message in
$SPLUNK_HOME/var/log/splunk/splunkd.log on Indexer and Heavy Forwarder. Also check whether receiving port is listening on Indexer.
