Check which guest(s) cause the high CPU usage by looking at the virtual machine tab of the host affected in the vSphere client. Sort it by the "Host CPU" column". Dig into these virtual machines then and check their task manager, which process causes such a high CPU load.

Maybe you have a problem, maybe it is normal and your host is too small to run the load.

Apart from checking what is said earlier. you can also look at the Alarm definition and check if the Alam trigger is set too low for the CPU usage. You can adjust that accordingly.

Hi,

You could click on the top level instance in vcenter and then on the left navigate to alarms and make the modification to alert threshold values.

Are the VMware tools installed in each guest?

How many cores does your host have and how many vCPUs have you assigned to your guests? Do all guests use multiprocessoring? If so, how many vCPUs do you assign to a guest by default?

Have you looked into the guests showing high utilization? Are there tasks which cause such a high load?
