Model Eviction in Log Analytics for PowerBI prem

[gmachowiak]

hi all,

We've successfully established the azure log analytics for premuim workspaces in powerbi.

I was wondering whether there model evictions will be logged as well and how if yes how to identify such event.

unfortunately the documentation is scarce

Hi  @gmachowiak 

When a semantic model is evicted due to capacity issues, causing a query or refresh to fail, there is a corresponding log. However, there is no documentation that directly identifies the attributes that match the eviction operation.
Based on this situation, you can create a semantic model eviction event, and then explicitly name the event by reporting the corresponding error. I hope this will give you some ideas.

Thanks for the answers.

So if i understood correctly:

• there semms not to be any direct log that would indicate an eviction of the model.
• there is an error log when operations fail due to evicted model - not really whan i'm looking for;

On the side not, I'm not really sure how would i create a sematic model eviction event (or any event for loggig) - is there any documentation i can have a look at?

Edit: Plus, are there any known ways of tracing the models' evictions?

Hi @gmachowiak 

As it stays today and previously mentioned, there is no way to find an event for eviction.

Hi @gmachowiak 

As far as I am aware, there is no logging to determine when a model gets evicted. You can create or vote for an idea at https://ideas.powerbi.com.
