Bug: #50002772 (SQL Hotfix)
Microsoft distributes Microsoft SQL Server 2005 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release.
Symptoms
In System Monitor, you define an alert activity on one of the following performance counters of an instance of Microsoft SQL Server 2005:
Performance objectPerformance counter
SQLServer:Access Methods Worktables From Cache Ratio
SQLServer:Broker/DBM TransportMsg Fragment Recv Size Avg
SQLServer:Broker/DBM Transport Msg Fragment Send Size Avg
SQLServer:Broker/DBM TransportReceive I/O Len Avg
SQLServer:Broker/DBM Transport Send I/O Len Avg
SQLServer:Buffer Manager Buffer cache hit ratio
SQLServer:Catalog MetadataCache Hit Ratio
SQLServer:Cursor Manager by Type Cache Hit Ratio
SQLServer:Databases Log Cache Hit Ratio
SQLServer:Latches Average Latch Wait Time (ms)
SQLServer:LocksAverage Wait Time Base (ms)
SQLServer:Plan Cache Cache Hit Ratio
SQLServer:Transactions Update conflict ratio
These performance counters should not appear in the performance counter list when you define an alert activity in System Monitor. Therefore, the alert activity is not executed when the alert criteria are met.

In SQL Server 2000, these performance counters do not appear in the performance counter list when you define an alert activity in System Monitor.
Cause
This issue occurs because these performance counters use an absolute value instead of a percentage value.
Resolution
The fix for this issue was first released in Cumulative Update 9. For more information about how to obtain this cumulative update package for SQL Server 2005 Service Pack 2, click the following article number to view the article in the Microsoft Knowledge Base:

Note Because the builds are cumulative, each new fix release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release.

By default, any hotfix that is provided in a SQL Server service pack is included in the next SQL Server service pack.
Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
