CPU Utilization of a CSS1150x

HI,

is it possible to monitor the CPU of a CSS 1150x.

I did not find any hint about this in the docs. I tried to figure out if it is pssoible via the HSE but was not able to find a way.

If gatherig the CPU-Utilization is not possible how to detect if a CSS is overloaded or reaches the limits. Maybe one can solve the "bottleneck" by adding another IOM or SAM.

Kind Regards,

Joerg

Joerg,

the command is 'sho system-resources'.

It will give you the cpu for each cpu.

You will also need to capture a 'flow stat' because the number of active flow is also a limitation important to watch. Make sure you're not running out of 'Number of Free fast-path FCBs'

Gilles.

Thanks for rating this answer.

Hi Gilles,

thanks for the information...

Is there a way to gather these values via SNMP?

Joerg,

yes the SNMP object exists for the CPU.

chassisMgrExt.mib: apChassisMgrExtSubModuleCPUInstantaneous Integer32,

chassisMgrExt.mib: apChassisMgrExtSubModuleCPUAverage Integer32,

chassisMgrExt.mib:apChassisMgrExtSubModuleCPUInstantaneous OBJECT-TYPE

chassisMgrExt.mib: "This object specifies the instantaneous CPU utilization."

chassisMgrExt.mib:apChassisMgrExtSubModuleCPUAverage OBJECT-TYPE

chassisMgrExt.mib: "This object specifies the average CPU utilization."

The free fcb info is not available but you can get the active FCB and the total FCB and then compare the 2 together.

flowMgrExt.mib: apFlowMgrStatIfCurrentActiveTCP Counter32,

flowMgrExt.mib: apFlowMgrStatIfCurrentActiveUDP Counter32,

flowMgrExt.mib: apFlowMgrStatIfTotalActiveFlows Counter32

Re: CPU Utilization of a CSS1150x

Hi Gilles,

thx for the information.

Another question came up lately. Is it possible to monitor the CPU usage via the HSE? If I have a look at the preconfigured reports for CPU Utilization I do not see the CSS to be watched. Only Switches, Routers and the SCA.

Can you tell me if the CSS is supported in the HSE or not and if yes which HSE release is necessary (WEBNE 7.2 is running right now on the CSS)

Thanks again.

Kind Regards,

Re: CPU Utilization of a CSS1150x

Hello

I graph the 5 min average apChassisMgrExtSubModuleCPUAverage

.1.3.6.1.4.1.9.9.368.1.34.17.1.14.1.1

.1.3.6.1.4.1.9.9.368.

should be replace by

.1.3.6.1.4.1.2467.

prior to upgrade 7.40
