F5 1500 9.4.7 - can snmpget Linux info, can't get Enterprise info

I'm trying to pull snmp data from single CPU 1500 running 9.4.7 software. I can manually pull host CPU and Memory stats using the Linux MIBs. I can also pull Ethernet stats with no problem.

 

 

However, whn I try to pull CPU utilization, I get errors.

 

Host CPU, 5 min avg: enterprises.2021.10.1.3.2 = "0.17" Hex: 30 2E 31 37

 

 

MultiHost Enterprise MIB:

 

Error in packet.

 

Reason: There is no such variable name in this MIB view (on this agent).

 

This name doesn't exist: enterprises.3375.2.1.7.5.2.1.1

 

 

MultiHost CPU Index:

 

Error in packet.

 

Reason: There is no such variable name in this MIB view (on this agent).

 

This name doesn't exist: enterprises.3375.2.1.7.5.2.1.2

 

 

 

I know it's a single CPU model. I verified it's a 1500 running 9.4.7. I verified I can do a manual snmpget on specific OIDs (but they seem to be generic Linux host OIDs). I can also do an snmpwalk. I'm not seeing teh Enterprise OIDs.

 

 

Is there something I need to verify in the snmpd-conf to make sure I'm letting the Enterprise MIBS be polled?

    I'm not sure the multi-host stuiff was in 9.4.7. IIRC that came in 9.4.8. Up to then it was a different OID (Not the 5 minute one either).

     

     

    I posted a walkF5Stats app a while back in codeshare that will gather CPU for several different versions. It should work with 9.4.7 as well.

    walkF5Stats is at

     

     

    https://devcentral.f5.com/wiki/iControl.walkF5Stats.ashx

     

     

    The CPU Stats (For 9.3 and later) uses the sysHostInfo OID's. The code looks like
