QAN just shown in several apps but not in other apps

Description:

Hello, I have two applications hosted on my server, Metabase and a web app, both of which are connected and querying a MySQL database. I’ve installed PMM (Percona Monitoring and Management) as a database monitoring tool. In the Query Analytics (QAN) section, why are the queries coming from the web app not showing up, while the queries from Metabase are visible?

How to solve the problem?.. Thanks

Version:

MySQL version 8. with perfschema method

Hi, it could be simply that your web app does not have any slow queries?
You can check performance_schema.events_statements_summary_by_digest table to see if there’s any.
