Expression Explanation:
The expression calculates the absolute change in CPU usage for containers by comparing the current rate of CPU usage (within the last 1 minute) with the rate of CPU usage from the previous minute. If this change exceeds 25%, the alert is triggered. Additionally, it compares the current rate of CPU usage with the rate from the previous 5 minutes to capture larger trends. If any of these conditions are met, the alert fires.
Alert Details:
- Alert Name: ContainerHighLowChangeCpuUsage
- Trigger Condition: Absolute change in CPU usage exceeding 25%
- Alert Severity: Informational (info)
* Add alert rule for high CPU usage change
