Query Analytics

● Speed up development - PMM creates a common language between DBA’s, developers, and sysadmins to help speed development and release cycles

● Identify the queries consuming the most amount of time● Default is grouped by the query abstract

○ Query Abstract - WHERE clause removed (replaced by '?')● Answers:

○ Which queries are causing the most amount of load in my Environment?○ How often do these queries run?○ How long do these queries take to execute?○ What other query characteristics exist to display and sort?
