MS SQL Server monitor not able to access named instance SQL counters in Sitescope

[Pradeep C]

I had set up MS SQL Server monitor in site scope to retrieve SQL counters from the database server. Initially, I always seen all SQL counters with 0 value. To fix this, another named instanses for SQL Counters created on the database server. After that I can see the counters for SQL named instance through perfmon on the site scope server. But in Sitescope SQL monitor, i was not able to see these instances. I tried with other monitors like Windows resources, but didn't help. Can someone help me on this... Many thanks.
