Fields
Field name |
Explanation |
---|---|
Available Mbytes |
Available size in the physical memory area (MB). The combined total of zero memory, free memory, and standby memory (cached) that can be immediately allocated to a process or be used by the system. Normally, if this value continues to be less than 5% of the value in the Total Physical Memory Mbytes field, it indicates that excessive paging is occurring.#1 |
Cache Faults/sec |
Number of page faults that occurred in file system caching (faults/second). |
Cache Mbytes |
Size of the file system cache being used (MB).#1 |
Copy Read Hits % |
Requests to read from the file system cache page (%). |
Copy Reads/sec |
Number of page reads from the file system cache, including memory copying from the cache to application buffer memory (reads/second). |
Pages/sec |
Rate of paging for the pages when page faults occurred (pages/second). The total of the values in the Pages Input/sec field and Pages Output/sec field. Normally, if this value continues to exceed 5, memory may have become a system bottleneck. |
Pool Nonpaged Bytes |
Size of physical memory that cannot be paged, that is, the location where a system component acquired an area when executing a task (KB). Normally, if the value in this field continues to increase when the server activity level is not increasing, a process with memory leak may be being executed.#1 |
Pool Paged Bytes |
Size of physical memory that can be paged, that is, the location where a system component acquired an area when executing a task (KB).#1 |
System Cache Resident Bytes |
Size of pageable physical memory inside the file system cache used by the OS code (the file system that is loaded by Ntoskrnl.exe, Hal.dll, boot driver, and Ntldr/osloader) (bytes).#1 |
