      Hi Michael,

      Good morning, and thank you so much for taking the time to respond to my question.

       

      My question is, why do we need to modify the logrotate settings to add the snmpd.log? Will that free up the 0% free space of the disk partition var and remove the restarting snmpd issue?

       

      Please specify the negative impact of the following modifications on our network and kindly explain what each command does.

      tmsh modify sys log-rotate syslog-include "/var/log/snmpd.log {

          compress

          missingok

          notifempty

          postrotate

              killall -HUP snmpd 2>/dev/null || true

          endscript

      }

        Hi,

        The Bug ID link that I provided was just a *guess* of what the problem may be. I would recommend generating a QKview file and raising a Service Request with F5 to properly diagnose the issue.
