How to monitor Async MDL Reads Persec for WMI Win32_PerfRawData_PerfOS_Cache ?

With IPHost Network Monitor you can run WMI Async MDL Reads Persec monitoring of various devices in your network.

To create a WMI monitor for Async MDL Reads Persec, provide host name (it must be a Windows host) and specify custom WQL query:

SELECT AsyncMDLReadsPersec FROM Win32_PerfRawData_PerfOS_Cache

Async MDL Reads/sec is the frequency of reads from the file system cache that use a Memory Descriptor List (MDL) to access the pages. The MDL contains the physical address of each page in the transfer, thus permitting Direct Memory Access (DMA) of the pages. If the accessed page(s) are not in main memory, the calling application program will not wait for the pages to fault in from disk.

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.
