We just added new
database-scoped configuration
options that will help with monitoring performance of natively compiled stored procedures. The new options XTP_PROCEDURE_EXECUTION_STATISTICS and XTP_QUERY_EXECUTION_STATISTICS are available now in Azure SQL Database, and will be available in the next major release of SQL Server. These options will improve your monitoring and troubleshooting experience for databases leveraging
In-Memory OLTP
with
natively compiled stored procedures
.
After enabling these options, you can monitor the performance of natively compiled stored procedures using
Query Store
, as well as the DMVs
sys.dm_exec_query_stats
and
sys.dm_exec_procedure_stats
. Note that there is a performance impact to enabling execution statistics collection, thus we recommend to disable stats collection when not needed.
To enable execution statistics collection at the procedure level, run:
ALTER DATABASE SCOPED CONFIGURATION SET XTP_PROCEDURE_EXECUTION_STATISTICS = ON
To enable execution statistics collection at the query level, run:
ALTER DATABASE SCOPED CONFIGURATION SET XTP_QUERY_EXECUTION_STATISTICS = ON
The following example queries show the procedure-level and query-level execution statistics for natively compiled stored procedures:
select object_id,
object_name(object_id) as 'object name',
cached_time,
last_execution_time,
execution_count,
total_worker_time,
last_worker_time,
min_worker_time,
max_worker_time,
total_elapsed_time,
last_elapsed_time,
min_elapsed_time,
max_elapsed_time
from sys.dm_exec_procedure_stats
where database_id=db_id() and object_id in (select object_id
from sys.sql_modules where uses_native_compilation=1)
order by total_worker_time desc
select st.objectid,
object_name(st.objectid) as 'object name',
SUBSTRING(st.text, (qs.statement_start_offset/2) + 1, ((qs.statement_end_offset-qs.statement_start_offset)/2) + 1) as 'query text',
qs.creation_time,
qs.last_execution_time,
qs.execution_count,
qs.total_worker_time,
qs.last_worker_time,
qs.min_worker_time,
qs.max_worker_time,
qs.total_elapsed_time,
qs.last_elapsed_time,
qs.min_elapsed_time,
qs.max_elapsed_time
from sys.dm_exec_query_stats qs cross apply sys.dm_exec_sql_text(sql_handle) st
where st.dbid=db_id() and st.objectid in (select object_id
from sys.sql_modules where uses_native_compilation=1)
order by qs.total_worker_time desc
