Metric Description
Application Application that submitted queries on the selected date
Burn Rate Percentage of the overall system capacity that was effectively consumed by all queries during their execution
Gating Efficiency Percentage indicating the overall query duration time spent executing versus being delayed. A value of 100% indicates all time was spent executing.
Impact CPU Impact of jobs on the system taking CPU skew into account. The value is equal to the highest CPU time in seconds consumed by any one AMP on behalf of a job or query multiplied by the number of AMPs.
Max Spool Total amount of temporary spool space used
Query Counts Total number of logged queries
Suspect Queries Number of queries designated as suspect based on thresholds set in the Query Log data collector
System System of the application that submitted queries on the selected date
System Utilization Percentage of the system's CPU that was utilized by the application for the particular day by logged queries
Time Active Amount of time in seconds that queries spent executing. Excludes any time queries were delayed before being executed.
Time Delay Amount of time in seconds that queries were delayed before being executed
Time Expansion Ratio of how long the query took to execute versus how long it could have ideally run. The larger the number, the more the execution time of the query was expanded. For example, a value of 10x to indicates an expansion of 10 times the ideal execution time.
Total AMP CPU Total amount of CPU consumed by AMPs in processing queries
Total I/O Total number of I/O requests
Total Parser CPU Total amount of CPU consumed by the parsing engine in processing queries
Version Version of the application that submitted queries on the selected date
