CPU utilization climbs above 90% on several VMs. This causes performance degradation for a business-critical application.
How can alerts be configured to notify the administrator before VM CPU utilization hits 90%?
A . On a CVM, use ncli to set the VM CPU Check threshold for the critical VMs to a value below 90%.
B . On the Health dashboard, locate the VM CPU Check and lower the alert threshold below 90%.
C . On a CVM, configure a cron job to run the VM CPU Check more frequently and email the result.
