The monitor alerts if a SSAS process consumes more CPU resources than specified by the threshold.

Knowledge Base article:

Summary

The monitor alerts if a SSAS process consumes more CPU resources than specified by the threshold.

Causes

SSAS instance processing consumes a lot of CPU capacity.

Resolutions

Evaluate why SSAS instance processing is using such a high CPU capacity percentage.

Name

Description

Default Value

Enabled

Enables or disables the workflow.

Yes

Generates Alerts

Defines whether the workflow generates an Alert.

Yes

Interval Seconds

The recurring interval of time in seconds in which to run the workflow.

900

Number of samples

Indicates how many times a measured value should breach a threshold before the state is changed.

4

Synchronization Time

The synchronization time specified by using a 24-hour format. May be omitted.

 

Critical Threshold (%)

The monitor alerts if the CPU utilization caused by the SSAS process is higher than the threshold.
