Usage

To understand the percentage of time the database server spends actively working on requests, use the following ratio:

(total_rqst_time - total_wait_time) / total_rqst_time

The value of the client_idle_wait_time monitor element is not included in the value of the total_wait_time monitor element. The total_wait_time element represents only time spent waiting while the database server is processing requests.
