F5 BIG-IP icon   F5 BIG-IP – Useful SNMP oids to monitor

I have collected some of the most interesting OIDs (in my scenario im using LTM and APM modules) from the F5 MIBS:

OIDs – System Data

Hardware sensors (fans, power supplies…), resource usage (cpu, mem…), sync status…

Synchronization status messagesysCmSyncStatusSummary.
Failover statussysCmFailoverStatusStatus
Synchronization status colorsysCmSyncStatusColor
Power Supply statussysChassisPowerSupplyStatus
Fan StatussysChassisFanStatus
Interface StatussysInterfaceStatus
Cpu UsagesysMultiHostCpuUsageRatio1m
Memory UsagesysMultiHostTable

OIDs – Access Policy Manager (APM)

Number of sessions in my VPN SSL portal

Active SessionsapmPaStatCurrentActiveSessions
Pending SessionsapmPaStatCurrentPendingSessions
Completed SessionsapmPaStatCurrentCompletedSessions

OIDs – Local Traffic Manager (LTM)

State of my pools servers and nodes (active nodes, number of connections…)

Pools/Nodes namesltmPoolMemberNodeName
Nodes Current ConnectionsltmNodeAddrStatServerCurConns
Nodes StatusltmPoolMemberMonitorStatus

Downloading MIB files

You can download the MIB files using the WEB gui (About -> Download section -> MIB files)

Output examples

These are the snmpwalk command outputs for some of these OIDs:

# snmpwalk -v2c -c public bigip1 F5-BIGIP-SYSTEM-MIB::sysCmFailoverStatusStatus
F5-BIGIP-SYSTEM-MIB::sysCmFailoverStatusStatus.0 = STRING: ACTIVE
# snmpwalk -v2c -c public bigip2 .
F5-BIGIP-SYSTEM-MIB::sysCmFailoverStatusStatus.0 = STRING: STANDBY

Note you can use either MIB name or OID format

# snmpwalk -v2c -c public bigip1 F5-BIGIP-SYSTEM-MIB::sysChassisPowerSupplyTable
F5-BIGIP-SYSTEM-MIB::sysChassisPowerSupplyIndex.1 = INTEGER: 1
F5-BIGIP-SYSTEM-MIB::sysChassisPowerSupplyIndex.2 = INTEGER: 2
F5-BIGIP-SYSTEM-MIB::sysChassisPowerSupplyStatus.1 = INTEGER: good(1)
F5-BIGIP-SYSTEM-MIB::sysChassisPowerSupplyStatus.2 = INTEGER: good(1)


# snmpwalk -v2c -c public bigip1 F5-BIGIP-LOCAL-MIB::ltmNodeAddrStatServerCurConns
F5-BIGIP-LOCAL-MIB::ltmNodeAddrStatServerCurConns."/LAN/EXCHANGE01" = Gauge32: 3341
F5-BIGIP-LOCAL-MIB::ltmNodeAddrStatServerCurConns."/LAN/EXCHANGE02" = Gauge32: 3383
F5-BIGIP-LOCAL-MIB::ltmNodeAddrStatServerCurConns."/LAN/PROXY01" = Gauge32: 2853
F5-BIGIP-LOCAL-MIB::ltmNodeAddrStatServerCurConns."/LAN/PROXY02" = Gauge32: 2631

Examples of Nagios monitoring F5 using SNMP

(i have been working on my own nagios plugins to parse the SNMP output and customize the sensors in Nagios)
