Since upgrading to 2025.0, I'm seeing a number of Instances Saturation Percent critical alerts for shared services. It appears that, if a request is received by one of these services, the Instances Saturation Percent metric goes to 100% for that interval. From what I understand, on a shared service, there are no configured service instances being used. The Instance Limits are "0 min - 0 max"
Is this normal or expected behavior? It is the cause of most of my Critical-level alerts, and I would like to minimize that.
As an example, here is the Instances Saturation Percent metric on one particular service
And here is the metric for Requests Received over that time:
And here is the metric showing Instances Used.
The intervals in which requests were received show an Instance Saturation of 100%, and an Instances Used metric of 0. You can see how they all line up in the charts. It seems like services with shared instance types should not be able to trigger this Critical alert. If I'm missing something, please let me know. Thanks.
