I'm using MySQL/InooDB
.
Currently slow query log is enabled on my server.
I want to see profiling result of a specific slow query when it executed. I know how to do profiling, but for me it's not much useful to do it after a query is logged as slow, because it always run very faster. Maybe the server load or another stress on server made that query slow and I need to know the reason.
Something like this:
# Query_time: 5.045559 Lock_time: 0.000021 Rows_sent: 1 Rows_examined: 1
SET timestamp=1481983357;
SELECT id FROM Table WHERE id=125;

+----------------------+----------+
15 rows in set (0.00 sec)
Is there any way to do it?
