SNMP Pools

I'm trying to probe the status of a pool via SNMP and not translating the whole pool name into an OID as doing that for each and every pool is not efficient. On the F5 I can run the following comma...
application delivery
LTM
nagios
oid
pool status
snmp
snmp walk

    Greetings,

    Did you allow access to the snmpv2c agent?

     

    tmsh modify sys snmp snmpv2c { allowed-addresses add { 10.10.10.0/24 }

tmsh list sys snmp snmpv2c allowed-addresses
sys snmp {
    allowed-addresses { 127.0.0.0/8 10.12.23.0/24 10.10.10.0/24 }
    snmpv2c {
}

I'm testing from a remote linux server, using the command you provided above. When all of the F5 MIBs are in the proper third party mib directory, the reponse is successful:

 

snmpwalk -v2c -c public 10.12.23.120 F5-BIGIP-LOCAL-MIB::ltmPoolStatusAvailState.\"/Common/Pool1\"
F5-BIGIP-LOCAL-MIB::ltmPoolStatusAvailState."/Common/Pool1" = INTEGER: red(3)

 

Move the F5 MIBs away , and of course it fails:

 

snmpwalk -v2c -c public 10.12.23.120 F5-BIGIP-LOCAL-MIB::ltmPoolStatusAvailState.\"/Common/Pool1\"
MIB search path: /root/.snmp/mibs:/usr/share/mibs/site:/usr/share/snmp/mibs:/usr/share/mibs/iana:/usr/share/mibs/ietf:/usr/share/mibs/netsnmp
Cannot find module (F5-BIGIP-LOCAL-MIB): At line 0 in (none)
F5-BIGIP-LOCAL-MIB::ltmPoolStatusAvailState."/Common/Pool1": Unknown Object Identifier

snmpwalk -v2c -c public 10.12.23.120 1.3.6.1.4.1.3375.2.2.5.5.2.1.2.13.47.67.111.109.109.111.110.47.80.111.111.108.49
iso.3.6.1.4.1.3375.2.2.5.5.2.1.2.13.47.67.111.109.109.111.110.47.80.111.111.108.49 = INTEGER: 3

 

So, I believe the query itself will work from a remote SNMP management station, it is just a matter of how the station is formatting the request. Are you able to:

1) Check any of the logs on the SNMP station to see if any errors are being thrown? 2) Get a packet capture on the BIG-IP system to see what the SNMP query looks like?

Sorry I don't have more info on this,

Kevin
