What is this alert?

Command Center samples CPU usage on all segment hosts every 15 seconds and calculates the average CPU usage for the cluster. An alert is raised if the average CPU usage is greater than the specified percentage for longer than the specified number of minutes.

What to do

Use the Command Center Query Monitor to identify currently running individual queries with high CPU usage.

Use the Command Center History view to see CPU load during the period prior to the alert and identify completed queries using too much CPU.

Check CPU usage using operating system utilities such as ps and top to identify any operating system processes that are consuming excessive CPU, for example backup, restore, or ETL processes.
