What does it mean when your CPU utilization is high?

A high CPU utilization and relatively low interrupt percentage indicates that one or more system processes is taking too much time. In this case, see the “Debugging Active Processes” section. When the interrupt percentage is high, the root cause of the problem is that the CPU is receiving too many packets.

Why does my switch never report 0% CPU utilization?

If the CPU is busy 5% of the time then the CPU is idle the other 95% of the time. The switch will never report CPU utilization at 0%. There are multiple background IOS processes running on timers that execute multiple times a second. This is why even in the simplest of deployments, the switch never reports 0% CPU utilization.

What does the CPU utilization history on Cisco show?

The CPU utilization history shows when the CPU is consistently receiving network packets, but it does not show the cause. Enter the Cisco IOS show processes cpu sorted 5sec privileged EXEC command to show the current the CPU utilization and which IOS processes are using the most CPU time.

What’s the average CPU utilization for a nonstacked switch?

Two other important numbers are shown on the same output line: the average utilization for the last 1 minute (6 percent in this example) and the average utilization for past 5 minutes (5 percent in this example). These values are typical for a nonstacked switch in a small and stable environment.

How to check CPU usage in service host?

Step 1. Assuming that you’re in the Task Manager. Expand the Service Host: Local System to see what items are using more disk, CPU or memory clearly. Step 2. Once identified the items that are hogging your computer resources, right-click on it and select End Task.

Why does service host take up so much memory?
