Introduction

This document describes the steps to monitor CPU and Memory in NCS5500 device. The examples are from a router having one LC and two RPs:

Monitoring CPU

CPUs on RPs and LCs (both XR and SysAdmin VM) can be monitored through SNMP. For eXR operating system we support monitoring for nodes for both XR and admin mode.

 

To list the index for each CPU, use either:

RP/0/RP0/CPU0:leaf-1#show snmp entity | i "Virtual processor for"
