Hi,
Following on from my script that looks at poorly performing queries, here’s one that helps to find procedures that may be performing poorly. It makes use of sys.dm_exec_procedure_stats and produces a result set that shows the following:
- [Object]
- [SQLText]
- [QueryPlan]
- [execution_count]
- [Avg. CPU Time(s)]
- [Avg. Physical Reads]
- [Avg. Logical Reads]
- [Avg. Logical Writes]
- [Avg. Elapsed Time(s)]
- [Total CPU Time(s)]
- [Last CPU Time(s)]
- [Min CPU Time(s)]
- [Max CPU Time(s)]
- [Total Physical Reads]
- [Last Physical Reads]
- [Min Physical Reads]
- [Max Physical Reads]
- [Total Logical Reads]
- [Last Logical Reads]
- [Min Logical Reads]
- [Max Logical Reads],
- [Total Logical Writes]
- [Last Logical Writes]
- [Min Logical Writes]
- [Max Logical Writes]
- [Total Elapsed Time(s)]
- [Last Elapsed Time(s)]
- [Min Elapsed Time(s)]
- [Max Elapsed Time(s)]
- cached_time
- last_execution_time
I hope you find it useful.
