Issue with log rotation

Path Finder

We have log files that are being monitored. Log files are deleted every 1 hour. We noticed that at the time of log rotation happens, some of the events are missed to indexed in splunk. How can I fix issue so that we don’t miss any data.

Hi maniu1609,
the easiest way (if possible) should be to rotate logs in a different file so you can read the last logs in the new file, after a few time (1 or 2 minutes) you can delete it, because the problem is that logs between the last Splunk ingestion and deletion (max 30 seconds) are missed.
If it isn't possible you can reduce Forwarder read interval but anyway you lose something.

Bye.

What does your monitor stanza look like, and how are you rotating (filename, compression, etc)?

we have log file aaa.log and if the log file is older than 1hr, then file will be deleted. File monitor stanza just has index, sourcetype and host_regex details alone.
