How to do ltmPoolStatServerCurConns triggers a snmp trap?

Hi everybody,

 

I need to configure a trap which it triggers an alert when there are no connections in a pool or even when there are connections. I found an OID:

 

ltmPoolStatServerCurConns .1.3.6.1.4.1.3375.2.2.5.2.3.1.8

 

By executing the snmpwalk command to the specific pool I obtain:

 

snmpwalk -v2c -c public localhost .1.3.6.1.4.1.3375.2.2.5.2.3.1.8.17.47.67.111.109.109.111.110.47.104.116.116.112.95.112.111.111.108

 

F5-BIGIP-LOCAL-MIB::ltmPoolStatServerCurConns."/Common/http_pool" = Counter64: 5

 

where I can see 5 current connections and the same result is obtained by a GET command from a snmp tool. The following link talks about how configure traps identifying a trappable log event: https://devcentral.f5.com/articles/custom-snmp-traps but for this case I don't know how to do this event triggers an alert and so customize this specific trap in a alert.conf file.

 

Maybe you already has configured something similar and you want share your experience.

    So you always want to get a trap when the con counter is >0 ? Or do you just want to check it in a specific interval e.g every hour or every x minutes etc?

     

  • Hello,

     

    The goal it would be when the trap be triggered in the moment when the counter be = 0 connections. But I think maybe it would be possible to configure a kind of iRule that it be checking each time period and when the result be ltmPoolStatServerCurConns = 0, this iRule generates an alert and we could create a customized trap.
