Workspace monitoring feature - experiences of users with capacity taken by the monitoring

I have put the workspace monitor feature on for 2 workspaces on a F8 capacity. This installs an eventstream hub on both workspaces.

Our capacity ran out of CU and started to do a lot of smoothing in the background for hours. 

 

I don't know whether it is caused by the monitoring itself or by the "semantic audit model notebook"  which i installed and ran into an error (fabric-toolbox/tools/SemanticModelAudit at main · microsoft/fabric-toolbox). 

But i would like to hear some experiences regarding performance when you put on the monitoring.

I do not know exactly whether this will solve it it might be the fabric accellerator - semantic audit itself, but I did not have the chance yet to review the latest version of the semantic audit accellerator.

Nevertheless to prevent this topic to be opened i will accept it

Hi @Spiedo 
Thank you for reaching out microsoft fabric community forum.

 

The high-capacity usage and smoothing behavior could be influenced by multiple factors, including the workspace monitoring feature and the Semantic Model Audit notebook execution.

Workspace monitoring adds an Eventhouse database that logs and tracks performance, which does use up compute resources. If you have multiple workspaces being monitored, that could be contributing to the capacity drain. On the other hand, the Semantic Model Audit notebook runs checks on your models, and depending on their size and complexity, it can be heavy on resources. If it hit an error mid-run, it might have left some processes hanging, which could also affect performance.

Few things you can try:

Check your capacity metrics in the Fabric Admin portal to see which workloads are consuming the most CU. Temporarily disabling monitoring for one workspace might help determine if that’s the issue. If you still need to run the audit notebook, try scheduling it during off-peak hours to avoid contention. And if CU usage is consistently maxing out, scaling up temporarily or adjusting workloads could help balance things out.
