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 |
Page Faults/sec |
Number of page faults that occurred (faults/second). Normally, if this value continues to exceed 5, it indicates a memory bottleneck. |
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. |
