Root cause has been isolated to service turning unhealthy after incorrect deployment which was impacting performance data view in Azure monitor when Azure mode is selected. To address this issue engineers are rolling back the service to previous healthy state. Some customers who have VM's sending data to workspaces, continue to experience issues seeing performance data in Azure monitor when Azure mode is selected and 5xx errors while viewing performance data on browser.

Update: Wednesday, 24 February 2021 22:01 UTC

We continue to investigate issues within Azure monitor for VM's. Preliminary investigation showed that the root cause was due to one of the back end component becoming inaccessible after a scheduled drill/test in EastUS2EUAP region. Further investigation shows that the root cause is due to regression that happened after a deployment on one of the back end services. Some customers who have VM's sending data to workspaces, continue to experience issues seeing performance data in Azure monitor when Azure mode is selected. Customers might also see 5xx errors while viewing the performance data on the portal.
