How to monitor a Cisco Router with HP NNM

Hi,

We have a network management console with HP NNM version B.06.20, and we need to monitor the utilization of the interfaces in several routers, two of this routers are 3640 IOS 12.0(5)T1. When we try to monitor these two routers all the interfaces show 0% utilization, which is false. We are using channalized E1 interfaces and fast Ethernet interfaces (nm-1fe-2ce1b/u). Does anyone know the reason of this failure and how to correct it?

Thanks in advance.

Use can use MRTG for the same thing (http://www.mrtg.org). It's a free ware :-)

No, we can not, it is company directive.

You can maually poll the objects and the do the math to calculate the utilization which will narrow down the issue as to whether HPOV is not showing it correclty or else.

Did you verify this from another SNMP manager or by doing a snmpget from the command line on the same MIB variabel? Could be that the 3640 is returning 0 by mistake or because you are retrieving from an instance other than you expect.

How precisely do you try to monitor the routers. NNM provides a MIB expressions which adds ifInOctets and ifOutOctets, multiplies it by 8 and divides it by the Bandwitdth of the interface. On the other hand, I think there are special variables in the Cisco private MIB (look for cisco->local->interface or similar) giving interface utilization.
