We have some servers in our environment where we cannot get accurate data fromdm_os_performance_counters. These servers are physical servers with multiple named instances and no default instance. When running a query fordm_os_performance_counters where object_name like '%Resource Pool%' we only receive values for aninstance_name of 'internal'. We have other servers on the same version of SQL Server (2008 R2 SP1) with only named instances and no default instance where the query properly returnsinstance_name values of 'default' and 'internal'.
How can I get instance_name = 'default' to show up on all servers?
I ask because I cannot get accurate CPU stats on the servers where an instance_nameof 'default' does not appear (the values for 'internal' are always 0)
Thank you!
