Use this command in order to show the CPU usage at the process level: switch#show processes cpu | ex 0.0 Buffers and the cache are included in the used memory statistics. Total memory, used memory, free memory, memory used for buffers, and memory used for cache in kilobytes. For a dual-core Supervisor, CPU is averaged across both cores. Number of processes in the system and how many processes are actually running when the command is issued.ĬPU usage percentage in user mode, kernel mode, and idle time in the last one second. The average reflects the system load over the past 1, 5, and 15 minutes. Use this command in order to display system-related CPU and memory statistics. Should be running but currently not running A hyphen (-) usually means a daemon not running on any particular terminal. Number of times a process has been started or restarted switch# show processesĬurrent program counter in hexadecimal format Use this command in order to display information about active processes.
Use the Cisco CLI Analyzer in order to view an analysis of show command output. The Cisco CLI Analyzer ( registered customers only) supports certain show commands. Commands and Scripts to Monitor Processes and CPUs Commands However, if average CPU usage remains high compared to normal, baseline CPU usage for a particular network, you might need to investigate high CPU usage.ĭefault hardware rate limiters (HWRL) and default control plane policing (CoPP) are enabled to help protect the supervisor inband interface on Nexus 7000 platforms. Therefore, the history option may report CPU spikes that do not necessarily indicate a problem. The Cisco NX-OS operating system takes advantage of preemptive CPU multitasking, so processes can take advantage of an idle CPU in order to complete tasks faster. Supervisor Engine 1 has a dual-core processor, Supervisor Engine 2 has a quad-core processor, and Supervisor Engine 2E has two quad-core processors. Unlike the Cisco Catalyst 6500 Series, there is no separate route processor (RP) and switch processor (SP). The Nexus 7000 platform is a Linux-based system with a preemptive scheduler that allows fair access to CPU resources for all processes. The commands and sample EEM script are based on Nexus 7000 Release 6.1 and earlier and are subject to change in future releases. This document describes common commands and processes to monitor CPU usage and troubleshoot high CPU usage issues on Cisco Nexus 7000 Series platforms.
