Hi,
I am a bit confused on the difference between query_time as reported in the mysql slow logs and the response time as reported by the Response Time Distribution (SHOW QUERY_RESPONSE_TIME;).
The confusion stems from the observation that the mysql slow logs shows the maximum query_time as 347s (when checked with all logs).
While the distribution has entries

As seen from the highlighted (red color fonts) there are 6 +47 =53 queries that are above the range of the maximum query_time as reported in the slow logs
The above would either imply that the response_time and query_time from the two are different. If so what is the difference between them?
Or if they are the same, then why did the mysql slow log not report/log 6+47 =53 query information.
