The dashboard monitoring shows active connections, but the connection monitoring in Grafana does not have active statistics. I couldn’t find any metrics that separately store active connections in Prometheus.

It wouldn’t be calculated like this, would it? “select count(*) from information_schema.processlist where Command !=‘Sleep’;”

By looking at the network calls, I discovered the tidb_server_tokens metric, which is also used in the performance overview → connection count panel.

:+1: That means it is calculated based on the obtained token.

It is also possible that the information is not synchronized.
