The Load as I see is, Average Active Sessions per second. The Query Count also shows Query Per Second. How are they different? I am certainly missing something. Maybe the “Load” is Average Active Sessions, when this query was running, but not all of them were necessarily running this query?
The Query Count is a sum of queries (number of queries) executed in a selected time period divided by the number of seconds in this time period - so it means the average number of queries per second.
The Load is a sum of the duration of execution of queries (how long queries run) divided by the number of seconds in the selected time period - we can understand it as how busy the database was by executing queries in the selected time range (please note: that a DB can executed queries in parallel - hance load can be bigger than 1).
