How to monitor MDL Reads Persec for WMI Win32_PerfRawData_PerfOS_Cache ?

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

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

SELECT MDLReadsPersec FROM Win32_PerfRawData_PerfOS_Cache

MDL Reads/sec is the frequency of reads from the file system cache that use a Memory Descriptor List (MDL) to access the data. The MDL contains the physical address of each page involved in the transfer, and thus can employ a hardware Direct Memory Access (DMA) device to effect the copy. The LAN Server uses this method for large transfers out of the server.

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.
