    Description

      Not an Observium bug but F5's.

      After upgrading from rev 5572 to 5768 one of our two F5 load balancers were showing 'snmp down' in Observium. Running a poller with debug, I can see one of the SNMP gets returns "No Such Object".

      In the output below, the RO string and hostnames were updated for security purposes. somef5-01 responds correctly while somef5-02 does not, despite running the same F5 code.

      This appears to be an F5 bug: http://support.f5.com/kb/en-us/solutions/public/15000/000/sol15064.html

      I'd hate to have to take an outage to upgrade our F5s for this problem. Is there any workaround in Observium or code modification to compensate for F5's fail SNMP code?

          [OBS-981] F5 Bug snmpget .1.3.6.1.2.1.1.2.0

          Thank you! Removed my workaround and confirmed the device is showing up now. somef5-02 shows up as a Linux host still but that is expected since the device is not responding correctly to the snmpget.

          Oh, seems this was a RusBug

          But anyway, this should be fixed in r5771.

          We're already on about the 5th workaround for various different devices not replying to various different OIDs.

          If we fix it for you, we break it for someone else. And you already know you it's fixed by F5.
