Hi All,

Wanted to know ,is there any checkpoint stored to allow splunk forwarder to skip events already sent earlier after reboot the spunk forwarder.I am using version 7.1.4.

and if its not skipping earlier events ,Is there an alternative way of removing duplications?

Kindly do the needful.

Hi,

When SplunkForwarder read file, it stores checkpoint(CRC) in fishbucket. Even after splunk service restart SplunkForwarder has all those checkpoint information in fishbucket.

Have a look at documentation https://docs.splunk.com/Documentation/Splunk/7.3.1/Data/Howlogfilerotationishandled so that you'll get idea how splunk reads rolling log files and how it calculates CRC.

Thanks for the clarification.

One more query ,if same event is being transffered towards splunk enterprise but from different sourc ,will it check in fishbucket?

No, it will not check. CRC stored in fishbucket for every file you monitor using SplunkForwarder.
