I am trying to use PRTG to monitor the number of "current connections" on a single Virtual Server on the F5 Big-IP's using SNMP. Has anybody been able to do this?

big-ip f5 snmp

The BIG-IP MIB file can be found by logging into the command line interface (via SSH) and looking at the following location:

/usr/contrib/f5/mibs/

Next, convert your MIB file to an OID using Paesslers MIB Importer

Look for ltmPoolStatServerCurConns (Oid 1.3.6.1.4.1.3375.2.2.5.2.3.1.8)

Hi,

Thanks for the reply, I managed to find some mibs in the following location: /usr/share/snmp/mibs. I imported a mib called F5-BIGIP-LOCAL-MIB.txt but the MIB importer went blank.

If it's a quite big MIB it might take a bit until the importer is finished loading it and the importer might show a blank screen during that time (and also use one CPU for 100%). Please simply let it run.

Thanks all for your help. It took a while but it did load. I did a partial MIB with ltm pool stat: ... pva current connections and max connections.

Thanks Again

I am attempting to do something similar to Vikesh.

After importing the F5 Local MIB, I chose to create a new SNMP Library sensor. I choose the Pool I wish to monitor using OID 1.3.6.1.4.1.3375.2.2.5.2.3.1.8 (ltm pool stat server cur conns) from the enumerated list of available pools. The value returned to the sensor varies wildly from a number in the billions to single digit. I excpect a value around 100. Is there any math I need to perform against the returned value? What am I missing?
