Edit me


Type a name for the custom counter. The name will be displayed in the Custom Counters drilldown.


For SQL Server queries, use T-SQL syntax. For Windows queries, use WMI. It is recommended that the query return only one column and one row. For all custom counter queries, Spotlight reads only the first column of the first row of data. Any additional data is ignored. To return multiple values, use more than one query. See the following for examples of custom counter queries.

Pages Allocated (SQL Server)

select cntr_value from sys.dm_os_performance_counters
where  object_name like '%:Access Methods%'
and    counter_name = 'Pages Allocated/sec'

Open Files (Windows)

SELECT FilesOpen FROM Win32_PerfRawData_PerfNet_Server
