Hi,
im using percona xtradb 8 + pmm2 under debian.
PMM2 frequently queries this select: “SELECT EVENT\_NAME, COUNT\_STAR, SUM\_TIMER\_WAIT FROM performance\_schema.events\_waits\_summary\_global\_by\_event\_name”
After a few days, this queries getting slower and slower (1sec+), and i have to restart the nodes to avoid high CPU usage.
Is there any way to truncate/reset the statistics? Or any way to disable pmm2 to collect these metrics? In fact I just want to collect the slow queries to analyze.
thanks

Hello @domby,
You need to re-add the mysql server in question to PMM using the pmm-admin tool and specify that the slow query source is slowlog, and not perfschema. Check the --help of pmm-admin for the exact syntax.
