Getting Data In

How to exclude from monitoring empty files?

Hello,

Monitor folders have many empty files. These files may be filled in the future. So I can't add them to a blacklist.
As result the log file splunkd.log has huge amount messages:

INFO  WatchedFile - File too small to check seekcrc, probably truncated. Will re-read entire file='<filename>'.

I don't want to reduce the log level.
Is it possible to exclude from monitoring empty files to reduce the message count in the log?

You could dump some filler into each file:

echo "FILLER: This is not real data but just filler text to suppress this log: INFO  WatchedFile - File too small to check seekcrc, probably truncated. Will re-read entire file='<filename>'." > <filename>.

Then configre props.conf and transforms.conf to send these events to nullQueue.

Hello, sorry for the delay.

It is fantastic solution and I marked this as a solution. But unfortunately I can't to change the source files (even empty).

Best regards, Artem.

Whatever you do, DO NOT use ignoreOlderThan because once Splunk ignores a file via this control, it will never check it again.

Universal forwarder start to reindex files when I commented the ignoreOlderThan parameter. I saw it today. The bitter experience with another task.

Best regards, Artem.
