How do I check CPU usage on a Cisco switch?
How do I check CPU usage on a Cisco switch?
To find CPU usage due to the subprocesses and tasks operating under a specific process, use the show process cpu detailed command. To sort for high activity usage, use show process cpu sorted command. CPU usage can be monitored on a per-switch basis in a stacked environment.
What does utilization mean on CPU?
processing resources
CPU utilization refers to a computer’s usage of processing resources, or the amount of work handled by a CPU. Certain tasks require heavy CPU time, while others require less because of non-CPU resource requirements.
What command would show the CPU utilization on the device?
The show processes cpu command displays overall router CPU utilization as well as the CPU utilization of each of the processes running on the router. The output CPU utilization for the past 5 seconds, past 1 minute and past 5 minutes.
How do you check utilization on a Cisco switch port?
Use the show interface port-utilization command to view a real-time rate display for all ports on the switch.
What is normal CPU usage?
Normal CPU usage is 2-4% at idle, 10% to 30% when playing less demanding games, up to 70% for more demanding ones, and up to 100% for rendering work. There are many factors which determine a “normal CPU usage” for your PC: CPU speed.
What does a high CPU utilization indicate?
If the CPU usage is around 100%, this means that your computer is trying to do more work than it has the capacity for. This is usually OK, but it means that programs may slow down a little. Computers tend to use close to 100% of the CPU when they are doing computationally-intensive things like running games.
What is maximum CPU utilization?
CPUs are designed to run safely at 100% CPU utilization. However, you’ll want to avoid these situations whenever they cause perceptible slowness in games.
How do I determine switch CPU utilization in Linux?
To determine switch CPU utilization, enter the show processes cpu sorted privileged EXEC command. The output shows how busy the CPU has been in the past 5 seconds, the past 1 minute, and the past 5 minutes. The output also shows the utilization percentage that each system process has used in these periods. Switch# show processes cpu sorted
When is high CPU utilization a problem on a switch?
When High CPU Utilization Is a Problem. These sections tell how to identify high CPU utilization and determine if it is a problem: In some instances, high CPU utilization is normal and does not cause network problems. High CPU utilization becomes a problem when the switch fails to perform as expected.
How much CPU usage is normal for a switch?
About the health it depends how the switch is configured and for what it was destined, for example a switch for servers or a switch for routing could generate more traffic than a switch for end users. Also a STP problem can generate high CPU utilization. Usually a switch for end users could use 10-20% of CPU resources.
What do the CPU utilization numbers mean on a CPU monitor?
The first number, 5%, tells how busy the CPU was in the past 5 seconds. This number is the total CPU utilization for all the active system processes, including the percentage of time at the interrupt level. The second number, 0%, shows the percentage of time at the interrupt level in the past 5 seconds.
