Monitoring the state of nodes, pools, and virtual servers with SNMP

So, I'm trying to gather the current state of nodes, pools, and virtual servers via SNMP for monitoring purposes. I can enumerate these things easy enough, but I cannot seem to put my finger on an OID that will report to me the current state (up/down/unknown) of each of these elements.

 

 

Has anyone had any luck here?

    I am using the iReasoning MIB browser from http://www.ireasoning.com/mibbrowser.shtml, plus a little experience wandering through the MIB tree.

     

     

    There are three OIDs that you might want to consider to report the state of a node:

     

     

    F5-BIGIP-LOCAL-MIB::ltmNodeAddrStatusAvailState

     

    F5-BIGIP-LOCAL-MIB::ltmNodeAddrStatusEnabledState

     

    and

     

    F5-BIGIP-LOCAL-MIB::ltmNodeAddrStatusDetailReason

     

     

    If you snmpwalk these OIDs, it will tell you how these are indexed in a table. So, for example:

     

    [root@b1500-912-1b:Active] config snmpget -v2c -c public localhost F5-BIGIP-LOCAL-MIB::ltmNodeAddrStatusAvailState.ipv4.4.10.1.0.20

     

    F5-BIGIP-LOCAL-MIB::ltmNodeAddrStatusAvailState.ipv4."10.1.0.20" = INTEGER: blue(4)

     

    [root@b1500-912-1b:Active] config

     

     

     

    There are three OIDs that you might want to consider to report the state of a pool:

     

     

    F5-BIGIP-LOCAL-MIB::ltmPoolAddrStatusAvailState

     

    F5-BIGIP-LOCAL-MIB::ltmPoolAddrStatusEnabledState

     

    and

     

    F5-BIGIP-LOCAL-MIB::ltmPoolAddrStatusDetailReason

     

     

    For virtual servers, I will leave it as an exercise for the reader. Hint:

     

    snmpwalk -v2c -c public localhost F5-BIGIP-LOCAL-MIB::ltmVirtualServStat

     

     

    If you have any questions, please contact me (206) 272-6465 and I will open a case for you
