The above display screen is broken into two parts. The header contains summary information about your MySQL server.

The first line identifies the hostname of the server and the version of MySQL it is running. The second line displays the total number of queries the server has processed in our case , the average number of queries per second, the number of slow queries, and the percentage of Select, Insert, Update, and Delete queries.

The third line shows real-time values since last mytop refresh. The normal refresh delay time for mytop is 5 seconds, so if queries were run in the last 5 seconds since the refresh, then the qps now number would be The first field is the number of queries per second qps now: 2.
