Hi @Thomas Sjödin Dahl Thank you for posting your question on Microsoft Q&A and for using Azure services.
Metrics are numerical values that describe some aspect of the resources of your server at a particular time. Monitoring your server's resources helps you troubleshoot and optimize your workload by allowing you to monitor what matters the most to you.
All Azure metrics have a one-minute frequency, and each metric provides 30 days of history. Reference: Monitor Azure Database for MySQL Flexible Server
Do you have 30 days of historical data.?
Regards,
Oury
