In an Azure Database for MySQL flexible server database I have set up, I'm looking at the Queries metric over the past 3 days at 15 minute intervals. At the beginning of this period, I see spikes in queries, corresponding to our initial accessing and testing of the database. Since then, the database has been left alone; we have not been actively querying the database. However, the metrics show a consistent rate of approximately 350 queries for every 15 minute interval. I am unable to attribute these queries to any action on our part.
Is this expected behavior? Is there a certain amount of 'default' querying that will be reported by the system? Does anyone have an idea as to where these queries may be coming from?
Thank you for any insight you can provide.
