Big-IP Monitoring

I would first determine if you are using the correct OUD and hopefully you imported the correct F5 Mibs. Secondly make sure you check with the ask F5 knowledge base to make sure you aren't running into the bug on snmp.

 

 

Hope that helps if you haven't solved it already.

Hi,

 

 

You should go to ask F5 and retrieve the document bigip_nsm_guide_943.pdf.pdf which is the BIG-IP® Network and System Management Guide.

 

 

Then check chapter 16 page 22.

 

 

You have here a lots of detailled information about how to calculate CPU usage.

You can use SNMP commands with various OIDs to gather and interpret

 

data on CPU use on the BIG-IP system. Specifically, you can gather and

 

interpret data for two different graph metrics: TMM CPU Usage and

 

CPU[0-n].

 

To gather and interpret the data for this metric, you must perform some

 

polling and calculations:

 

• First, you must use the OID to perform two separate polls, at an interval

 

of your choice.

 

• Next, you calculate the delta of the two poll values.

 

• Finally, you perform a calculation on the OID delta.

 

 

Table 16.13 shows the individual OIDS that you must poll, retrieving two

 

separate poll values for each OID.

I'm having a similar problem with Orion NPM. We are running version 9.0 SP2 and the Big-IP is running version 9.4.4 Build 73.1 Hotfix HF1.

 

However, Orion NPM is not recognizing the manufacturer/vendor as F5 nor is it able to identify what the machine type is and I am not getting any readings on CPU utilization.

 

I realize that I need to use some custom pollers with the F5 to get the additional information such as pools and virtual servers but do I also have to use a custom poller to get CPU utilization?

 

And what do I need to do in order for Orion to determine the manufacturer as F5?
