Usage Metrics - Unable to load the model

Hello Xiaoxin Sheng and thank you for your answer,

The feature "Usage Matrics" is working fine for all dashboards in all Workspaces except one.

It was working fine in this workspace too until we created a Homemade Usage Metrics dashboards.

At save time it displayed error on each and every objects with message about Data Model unable to be loaded.

Since then, on this Workspace, there's no way to see any Usage Metrics at all, and when I click "Edit" on my homemade Usage Metrics I cannot see any fields anywhere (see screenshots attached) so I can't revert what I did... I also tried deleting the homemade dashboard but it doesn't change anything, the model is still not loaded anymore.

It really looks like if we broke the data model of usage metrics :(

Anonymous: I carefully read the 2 links you mentionned and they doesn't help me too much.

I also confirmed with Admins that feature is turn on.

I've got to say that I'm a bit lost

Any help would be great.

Thank you

Brice
