/var/log/ltm on Standby references Active

I just noticed a very weird and disconcerting behavior on a couple of my 10.2.4HF3 LTM pairs. At times, I see Pool Member status (up/down) messages referencing the name of the Active unit in /var/log/ltm on the Standby. These particular log entry times match exactly on both units. But there are other times where the Standby reports status changes on its own referencing its own name, and these times don't match with corresponding entries on the Active. I don't see any messages referencing the Standby in /var/log/ltm on the Active.

 

 

This is an example of a message I see in /var/log/ltm on the Standby:

 

Aug 10 08:56:09 local/(name_of_active_unit) notice mcpd[4686]: 01070727:5: Pool member xxx.xxx.xxx.xxx:yyyy monitor status up.

 

 

 

Does anyone else see this behavior?

    Hi SMP,

     

     

    That's an odd one. Can you open a case with F5 Support and let us know what you figure out?

     

     

    Thanks, Aaron

    I think I just had a lightbulb moment. I have customized our UCS files to include /var/log/ltm, and I think it is getting overwritten on the Standby every time we do a ConfigSync.

     

     

    Is there some technique I can use to retain /var/log/ltm and some other files during a UCS backup, but not install them during a ConfigSync?

    Hmm.. any reason you need to include /var/log/ltm in a ucs? What about sending the logfile to a remote syslog server?

    No syslog server is available to me in this particular environment. The file is as a historical reference to justify and confirm lots of information.
