System CPU Usage Alerts


System CPU alerts indicate that the CPU usage of the MongoDB process has reached a specified threshold. This threshold is specified when the alert is created.

Common Triggers

System: CPU (Steal) %

Occurs when the percentage of time the CPU is in a state of “involuntary wait” exceeds the specified threshold. CPU steal percentage is the percentage by which the CPU usage exceeds the guaranteed baseline CPU credit accumulation rate.


This alert typically triggers when all credits have been consumed on an AWS burstable performance instance.

System: CPU (User) %
Occurs when the CPU usage of the MongoDB process, as normalized by the number of CPUs, exceeds the specified threshold.
