Nagios Support Forum

As instructed changes were done and also i am attaching the log file

It looks like there is a bug in version Core version 4.0.1 that was fixed in 4.0.2 for the log rotations which should fix what you are seeing.
If you update to a newer version or Nagios Core, it should fix the issue you are having.

Thanks tgriep,

I felt the same, But we also have another server to monitor different host and service with the same version and also the same configuration it works fine. This situation is getting me confused.

Thanks again for your support. I will get back to you once the changes done.

Let us know how it works out for you.

Hi Sasi,

You said you have one more Nag_Server with the same configuration, so I trust your other server's log also should be same - like contains only one hour data.
Please ensure that which will be helpful to debug?
#Log Rotation Mode
#Current Log file i.e, nagios.log (not entire data - just confirmation that nagios recording 24hrs log)
#Same check required in archives log
Also can you share us the version of the Nagios in the alternate server?

Perhaps, i think you have mentioned "auto save retention data" timelimit as 60minutes in your nagios.cfg, which makes nagios to record its current status in "retention.dat" which is also copied to the nagios.log as well as messages.log.

Try this:
retention_update_interval=60
retention_update_interval=0

By doing this you will disable auto save retention and you should check for the status of the log file? Just guessing
So once you do that within 1 hr you could check whether 2hr log is written to nagios.log, instead of auto save retention data completed.

The data is getting to the nagios.log file, just not to the archives.
I am interested the version of the other system too.
