Monitoring CPU and Memory of CSS11800 via SNMP

Level 1

Hello,

We want to monitor the cpu of a few of our CSS's.

Does someone know how the average of "apChassisMgrExtSubModuleCPUAverage" is calculated?

Also, I can't seem to find a variable to check the free memory.

Kind Regards,

Joeri

Hi Joeri,

SNMP MIB numeric definations

********FOR CPU******

For Instantaneous CPU load:

ASN Name: apChassisMgrExtSubModuleCPUInstantaneous

Object Identifier: 1.3.6.1.4.1.2467.1.34.17.1.13

Index Value: .

Description: This object specifies the instantaneous CPU utilization.

For five-minute-average CPU load:

ASN Name: apChassisMgrExtSubModuleCPUAverage

Object Identifier: 1.3.6.1.4.1.2467.1.34.17.1.14

Index Value: .

Description: This object specifies the average CPU utilization

This OID should be monitored periodically.

For Example:

To monitor the Instantaneous CPU load on SCM 7/1

snmpget ?c .1.3.6.1.4.1.2467.1.34.17.1.13.7.1

To monitor the 5-minute-average CPU load on SCM 7/1

snmpget ?c .1.3.6.1.4.1.2467.1.34.17.1.14.7.1

*****FOR Free Memory*****

ASN Name: apChassisMgrExtSubModuleSystemHeapFree

Object Identifier: 1.3.6.1.4.1.2467.1.34.17.1.10

Index Value: .

Description: This object identifies the amount of available system memory.

This OID should be monitored periodically.

For example:

To monitor the amount of free memory on SCM 7/1:

snmpget ?c .1.3.6.1.4.1.2467.1.34.17.1.10.7.1

To monitor the amount of free memory on SFM 9/1:

snmpget ?c .1.3.6.1.4.1.2467.1.34.17.1.10.9.1

****FOR Installed Memory*******

ASN Name: apChassisMgrExtSubModuleInstalledMemory

Object Identifier: 1.3.6.1.4.1.2467.1.34.17.1.12

Index Value: .

Description: This object specifies the amount of memory present on the submodule.

For example:

To obtain the amount of memory installed on SCM 7/1:

snmpget ?c .1.3.6.1.4.1.2467.1.34.17.1.12.7.1

To obtain the amount of memory installed on SFM 6/2:

snmpget ?c .1.3.6.1.4.1.2467.1.34.17.1.12.6.2

You can find the MIBS on CSS itself.I hope that answers your question.
