I have a splunk forwarder monitoring a folder and forward it to splunk server. However during reboot of splunk server, the log entries during reboot was lost.
No retry in splunk forwarder?
Forwarders are supposed to hold data while the indexer restarts and resume sending once the indexer is available again. How long was the indexer down? How much data is the forwarder trying to send during the outage? Are there any error messages in the forwarder's splunkd.log file?
