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…
MIB: F5-BIGIP-SYSTEM-MIB (file F5-BIGIP-SYSTEM-MIB.txt)

Synchronization status message	sysCmSyncStatusSummary	.1.3.6.1.4.1.3375.2.1.14.1.4
Failover status	sysCmFailoverStatusStatus	.1.3.6.1.4.1.3375.2.1.14.3.2
Synchronization status color	sysCmSyncStatusColor	.1.3.6.1.4.1.3375.2.1.14.1.3
Power Supply status	sysChassisPowerSupplyStatus	.1.3.6.1.4.1.3375.2.1.3.2.2.2.1.2
Fan Status	sysChassisFanStatus	.1.3.6.1.4.1.3375.2.1.3.2.1.2.1.2
Interface Status	sysInterfaceStatus	.1.3.6.1.4.1.3375.2.1.2.4.1.2.1.17
Cpu Usage	sysMultiHostCpuUsageRatio1m	.1.3.6.1.4.1.3375.2.1.7.5.2.1.27
Memory Usage	sysMultiHostTable	.1.3.6.1.4.1.3375.2.1.7.4.2

OIDs – Access Policy Manager (APM)

Number of sessions in my VPN SSL portal
MIB: F5-BIGIP-APM-MIB (file F5-BIGIP-APM-MIB.txt)

Active Sessions	apmPaStatCurrentActiveSessions	.1.3.6.1.4.1.3375.2.6.1.1.3.1.5
Pending Sessions	apmPaStatCurrentPendingSessions	.1.3.6.1.4.1.3375.2.6.1.1.3.1.6
Completed Sessions	apmPaStatCurrentCompletedSessions	.1.3.6.1.4.1.3375.2.6.1.1.3.1.7

OIDs – Local Traffic Manager (LTM)

State of my pools servers and nodes (active nodes, number of connections…)
MIB: F5-BIGIP-LOCAL-MIB (F5-BIGIP-LOCAL-MIB.txt)

Pools/Nodes names	ltmPoolMemberNodeName	.1.3.6.1.4.1.3375.2.2.5.3.2.1.19
Nodes Current Connections	ltmNodeAddrStatServerCurConns	.1.3.6.1.4.1.3375.2.2.4.2.3.1.9
Nodes Status	ltmPoolMemberMonitorStatus	.1.3.6.1.4.1.3375.2.2.5.3.2.1.11

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 .1.3.6.1.4.1.3375.2.1.14.3.2 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)

Sync status

HW status

CPU graphs

Pool and nodes connections

Pool and nodes state
