How to monitor Read Aheads Persec for WMI Win32_PerfFormattedData_PerfOS_Cache ?

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

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

SELECT ReadAheadsPersec FROM Win32_PerfFormattedData_PerfOS_Cache

Read Aheads/sec is the frequency of reads from the file system cache in which the Cache detects sequential access to a file. The read aheads permit the data to be transferred in larger blocks than those being requested by the application, reducing the overhead per access.

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.
