Some metrics are not reporting for the MySQL sensor


You are missing some metrics like Latency, Wait Events in the Instana dashboard for MySQL.


This problem can occur if there is an issue with the performance_schema installation on the node. You can easily verify this problem by looking up for the below permission denied errors in the agent logs:

2018-10-22T12:24:01.389-03:00 | ERROR | instana-scheduler-thread-2 | Mysql | com.instana.sensor-mysql - 1.1.55 | Error during sense in MySQL sensor
java.sql.SQLException: (conn=55691) Can't find file: './performance_schema/events_waits_summary_global_by_event_name.frm' (errno: 13 - Permission denied)

You can resolve this issue by performing a re-setup of the schema. If the problem still persists then please contact Support.
