This object deprecates the object cpmCPUTotal5min and increases the value range to (0.100). This object deprecates the object cpmCPUTotal1min and increases the value range to (0.100).ĬpmCPUTotal5minRev(.1.3.6.1.4.1.9.9.109.1.1.1.1.8): The overall CPU busy percentage in the last five-minute period. This object deprecates the object cpmCPUTotal5sec and increases the value range to (0.100).ĬpmCPUTotal1minRev(.1.3.6.1.4.1.9.9.109.1.1.1.1.7): The overall CPU busy percentage in the last one-minute period. Based on the platform, some routers that run at 90 percent, for example, 2500s, can exhibit performance degradation versus a high-end router, for example, the 7500 series, which can operate fine.ĬpmCPUTotal5secRev(.1.3.6.1.4.1.9.9.109.1.1.1.1.6): The overall CPU busy percentage in the last five-second period. The recommended baseline rising threshold for cpmCPUTotal5minRev is 90 percent. These MIBs enable you to monitor the trends and plan the capacity of your network. These MIB objects are not accurate because they look at CPU at one minute and five second intervals, respectively. The cpmCPUTotal5minRev MIB object provides a more accurate view of the performance of the router over time than the MIB objects cpmCPUTotal1minRev and cpmCPUTotal5secRev. From the CISCO-PROCESS-MIB, the cpmCPUTotal5minRev MIB object value reports the percentage of the processor in use over a five-minute average.

Thus, if CPU utilization is very high, it is possible that a routing update cannot be handled, or a process-switching packet is dropped.

Procedure for Devices with Single CPUĬritical router functions, like routing protocol processing and process packet switching, are handled in memory and share the CPU. Refer to Cisco Technical Tips Conventions for more information on document conventions. If your network is live, ensure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. The c7500 example with multiple CPUs uses Cisco IOS Software Release 12.0(22)S3. The information in this document is only for devices that run Cisco IOS software.

There are no specific requirements for this document. This document describes how to collect CPU utilization on Cisco IOS® devices that use Simple Network Management Protocol (SNMP).
