Introduction
This document describes how to monitor Aggregation Services Router 1000 (ASR 1000) CPU through the Simple Network Management Protocol (SNMP) utility.
Prerequisites
Requirements
Cisco recommends that you have knowledge of the SNMP Configuration.
Components Used
The information in this document is based on these software and hardware versions:
- Cisco IOS® XE
- ASR1000
- SNMP
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
Background Information
There are various ways and commands available to monitor ASR1000 CPU and it becomes very much important to monitor it all the time. SNMP is one of the utilities to monitor the CPU of ASR1000 systems. You can find various show commands output and SNMP walk results In this article.
Problem: How to Correlate the show Commands Output with the SNMP Results to Monitor ASR1000 CPU?
In this document, you can see how to monitor the CPU of different modules such as Route Processor (RP), Extended Services Processor (ESP), and SPA Interface Processor (SIP) that reside on the ASR1000 router.
Solution
There are two types of CPU to monitor:
1. Control Plane CPU - Available on RP, ESP, and SIP.
2. Data Plane CPU - Available on Quantum Flow Processor (QFP) (resides on ESP)
List of show Commands to Monitor ASR1000 CPU
Control Plane CPU:
- show proc cpu sorted | ex 0.00
- show processes cpu platform sorted
- show platform software status control-processor brief
- show process cpu platform location <R0/F0/0>
Data Plane CPU:
- show platform hardware qfp active datapath utilization
Correlate SNMP OIDs with show Commands
When you use show proc cpu sorted | ex 0.00, the output generated is this:
ASR1002#show proc cpu sorted | ex 0.00
CPU utilization for five seconds: 51%/0%; one minute: 44%; five minutes: 25%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process

411 191924 4812122 39 0.08% 0.03% 0.05% 0 MMA DB TIMER
This command only shows processes inside the IOS daemon.
Please use 'show processes cpu platform sorted'
to show processes from the underlying operating system.

Here, it gives the output in the order of SIP, RP, and ESP for 5 sec, 1 min, and 5 min. In Dual RP/ESP platforms, you can use the active RP/ESP. For example, if ESP1 is active then the command must be show process cpu platform location F1. You can use show process cpu platform location <RP/FP> active command also, but this is only for RP/ESP. For SIP, you have to specifically mention the location (slot).
When you use show platform hardware qfp active datapath utilization, the output generated is this:
