Could I know this query?

hi,

this query is slow query in my database.


<Query>

SELECT
EVENT_NAME,
COUNT_READ, SUM_TIMER_READ, SUM_NUMBER_OF_BYTES_READ,
COUNT_WRITE, SUM_TIMER_WRITE, SUM_NUMBER_OF_BYTES_WRITE,
COUNT_MISC, SUM_TIMER_MISC
FROM performance_schema.file_summary_by_event_name;


as I know, this query is executed by pmm

and it takes 3~4 sec.

could I know which graph is related with this query?

and, could I turn off this query in pmm?


thanks.
