SNMP Failover

We have 2 LTMs running as redundant devices. We want to get alerts when one box fails over to the other box. Is there a OID(s) that would detect a failover event.

Here is how I did this using SNMP polling

 

 

I downloaded MIBS(F5-BIGIP-SYSTEM-MIB) from the LTM unit into my monitoring tool. In this case HP's SiteScope.

 

 

Set the the counter path to the following:

 

 

starting OID = 1

 

Counter: iso/org/dod/internet/private/enterprises/f5/bigipTrafficMgmt/bigipSystem/sysGlobals/sysGlobalAttrs/sysGlobalAttr/sysAttrFailoverUnitMask

 

 

sysAttrFailoverUnitMask = 3 = Primary

 

sysAttrFailoverUnitMask = 0 = Secondary

 

 

I setup to 2 monitors, 1 for each LTM. If the Primary reports 0 it alerts. If the secondary goes to 3 it alerts.

 

 

Hope this helps.

 

 

If anyone else has a better OID please post.
