How to monitor MDL Read Hits Percent for WMI Win32_PerfFormattedData_PerfOS_Cache ?

With IPHost Network Monitor you can run WMI MDL Read Hits Percent monitoring of various devices in your network.

To create a WMI monitor for MDL Read Hits Percent, provide host name (it must be a Windows host) and specify custom WQL query:

SELECT MDLReadHitsPercent FROM Win32_PerfFormattedData_PerfOS_Cache

MDL Read Hits is the percentage of Memory Descriptor List (MDL) Read requests to the file system cache that hit the cache, i.e., did not require disk accesses in order to provide memory access to the page(s) in the cache.

The Cache performance object consists of counters that monitor the file system cache, an area of physical memory that stores recently used data as long as possible to permit access to the data without having to read from the disk. Because applications typically use the cache, the cache is monitored as an indicator of application I/O operations. When memory is plentiful, the cache can grow, but when memory is scarce, the cache can become too small to be effective.
