SQL Server: Latches Object
The Latches object in Microsoft® SQL Server™ provides counters to monitor internal SQL Server resource locks called latches. Monitoring the latches to determine user activity and resource usage can help you to identify performance bottlenecks.
These are the SQL Server Latches counters.
|SQL Server Latches counters||Description|
|Average Latch Wait Time (ms)||Average latch wait time (in milliseconds) for latch requests that had to wait.|
|Latch Waits/sec||Number of latch requests that could not be granted immediately.|
|Total Latch Wait Time (ms)||Total latch wait time (in milliseconds) for latch requests in the last second.|
