BUG #: 235555 (SHILOH)
In the SQL Server Books Online topic Using SQL Server Objects, SQL Server object names are all listed as beginning with "SQL Server"; however, for SQL Server 2000 named instances the SQL Server object names actually show up in Performance Monitor as "MSSQL$InstanceName." If there is a SQL Server 7.0 instance or default SQL Server 2000 instance on the same computer as one or more SQL Server 2000 instances, the SQL Server 7.0 or default SQL Server 2000 instance counters show up as "SQL Server."
In this example, the SQL Server 2000 Instance Name is SQL1:
Books Online Counter Name Actual SQL Server 2000 Counter Name for named Instance SQL Server: Access Methods MSSQL$SQL1:Access Methods SQL Server: Backup Device MSSQL$SQL1:Backup Device SQL Server: Buffer Manager MSSQL$SQL1:Buffer Manager SQL Server: Cache Manager MSSQL$SQL1:Cache Manager SQL Server: Databases MSSQL$SQL1:Databases SQL Server: General Statistics MSSQL$SQL1:General Statistics SQL Server: Latches MSSQL$SQL1:Latches SQL Server: Locks MSSQL$SQL1:Locks SQL Server: Memory Manager MSSQL$SQL1:Memory Manager SQL Server: Replication Agents MSSQL$SQL1:Replication Agents SQL Server: Replication Dist. MSSQL$SQL1:Replication Dist. SQL Server: Replication Logreader MSSQL$SQL1:Replication Logreader SQL Server: Replication Merge MSSQL$SQL1:Replication Merge SQL Server: Replication Snapshot MSSQL$SQL1:Replication Snapshot SQL Server: SQL Statistics MSSQL$SQL1:SQL Statistics SQL Server: User Settable Object MSSQL$SQL1:User Settable Object
A new format was needed to accommodate named instances in SQL Server 2000.
Only counters for those SQL Servers started prior to opening Performance Monitor are available.
