How to: Create a Set with a Generic T-SQL Query Collector Type

You can create a custom collection set with collection items that use the Generic T-SQL Query collector type by using the stored procedures that are provided with the data collector. Accomplishing this task involves using Query Editor in SQL Server Management Studio to carry out the following procedures:

  • Configure upload schedules.

  • Define and create the collection set.

  • Define and create a collection item.

  • Verify that the collection set and collection items exist.

Note

Before you create a custom collection set, you must configure data collection parameters. For more information, see How to: Configure Data Collection Parameters.

Define and create the collection set

  • Define a new collection set using the sp_syscollector_create_collection_set stored procedure.

    USE msdb
DECLARE @collection_set_id int
DECLARE @collection_set_uid uniqueidentifier
EXEC sp_syscollector_create_collection_set 
@name=N'DMV Test 1', 
@collection_mode=0, 
@description=N'This is a test collection set', 
@logging_level=1, 
@days_until_expiration=14, 
@schedule_name=N'CollectorSchedule_Every_15min', 
@collection_set_id=@collection_set_id OUTPUT, 
@collection_set_uid=@collection_set_uid OUTPUT
SELECT @collection_set_id, @collection_set_uid

    The collection mode can be set to either 0 (cached) or to 1 (non-cached).

    The logging level can be set to 0, 1 or 2. For more information about logging levels, see Data Collector Logging.

    The following preconfigured schedules are provided with the data collector:

    • CollectorSchedule_Every_5min

    • CollectorSchedule_Every_10min

    • CollectorSchedule_Every_15min

    • CollectorSchedule_Every_30min

    • CollectorSchedule_Every_60min

    • CollectorSchedule_Every_6h

    If you do not want to use one of the schedules that are provided, you can create a new schedule and use it for the collection set. For more information, see Creating and Attaching Schedules to Jobs.

Define and create a collection item

  1. Because the new collection item is based on a generic collector type that is already installed, you can run the following code to set the GUID to correspond to the Generic T-SQL Query collector type.

    DECLARE @collector_type_uid uniqueidentifier
SELECT @collector_type_uid = collector_type_uid FROM [msdb].[dbo].[syscollector_collector_types] 
WHERE name = N'Generic T-SQL Query Collector Type';
DECLARE @collection_item_id int

  2. Use the sp_syscollector_create_collection_item stored procedure to create the collection item. Declare the schema for the collection item so it maps to the schema that is required for the Generic T-SQL Query collector type.

    EXEC sp_syscollector_create_collection_item 
@name=N'Query Stats - Test 1', 
@parameters=N'
<ns:TSQLQueryCollector xmlns:ns="DataCollectorType">
<Query>
<Value>SELECT * FROM sys.dm_exec_query_stats</Value>
<OutputTable>dm_exec_query_stats</OutputTable>
</Query>
</ns:TSQLQueryCollector>', 
@collection_item_id=@collection_item_id OUTPUT, 
@frequency=5, 
@collection_set_id=@collection_set_id, 
@collector_type_uid=@collector_type_uid
SELECT @collection_item_id

Verify that the new collection set and collection item exist

  • Before starting the new collection set, run the following query to verify that the new collection set and its collection item have been created.

    USE msdb
SELECT * FROM syscollector_collection_sets
SELECT * FROM syscollector_collection_items
GO

    You can also do a visual check in SQL Server Management Studio. In Object Explorer, expand the Management node, and then expand Data Collection. The new collection set will be displayed. The red circle icon for the collection set indicates that the collection set is stopped.

Example

The following code sample combines the examples that are documented in the previous steps. Note that the collection frequency that is set for the collection item (5 seconds) is ignored because the collection set collection mode is set to 0, which is cached mode. For more information, see Data Collection Terminology.

USE msdb;

DECLARE @collection_set_id int;
DECLARE @collection_set_uid uniqueidentifier

EXEC dbo.sp_syscollector_create_collection_set
    @name = N'DMV Stats Test 1',
    @collection_mode = 0,
    @description = N'This is a test collection set',
    @logging_level=1,
    @days_until_expiration = 14,
    @schedule_name=N'CollectorSchedule_Every_15min',
    @collection_set_id = @collection_set_id OUTPUT,
    @collection_set_uid = @collection_set_uid OUTPUT
SELECT @collection_set_id,@collection_set_uid

DECLARE @collector_type_uid uniqueidentifier
SELECT @collector_type_uid = collector_type_uid FROM syscollector_collector_types 
WHERE name = N'Generic T-SQL Query Collector Type';

DECLARE @collection_item_id int
EXEC sp_syscollector_create_collection_item
@name= N'Query Stats - Test 1',
@parameters=N'
<ns:TSQLQueryCollector xmlns:ns="DataCollectorType">
<Query>
  <Value>select * from sys.dm_exec_query_stats</Value>
  <OutputTable>dm_exec_query_stats</OutputTable>
</Query>
 </ns:TSQLQueryCollector>',
    @collection_item_id = @collection_item_id OUTPUT,
    @frequency = 5, -- This parameter is ignored in cached mode
    @collection_set_id = @collection_set_id,
    @collector_type_uid = @collector_type_uid
SELECT @collection_item_id
   
GO
