Measures reported by SwapTest

Swap space is space on a hard disk used as the virtual memory extension of a computer's real memory (RAM). The least recently used files in RAM can be "swapped out" to the hard disk until they are needed later so that new files can be "swapped in" to RAM. Having an appropriate amount of swap space is important for optimal system performance. The measures made by the SwapTest are as follows:

Measurement Description Measurement Unit Interpretation
Swap_used The total swap space that is either allocated or reserved MB

 

Swap_allocated The total swap space currently allocated for use as a backing store MB  
Swap_reserved The total amount of swap space not currently allocated but claimed for future use MB This measure is available only for Solaris hosts.
Swap_available The total swap space that is currently available for future reservation and allocation MB  
Pct_swap_used The percentage of swap space that is allocated or reserved Percent A value close to 100% indicates that the swap space configured may not be sufficient. A value close to 0 may imply that the swap space configured may be too large.
Swap_queue Number of processes swapped out currently Number Ideally, this value should be close to 0. This measure is available for Solaris systems only, and not Linux/HPUX systems.
