Having an appropriate amount of swap space is important for optimal system performance. Simple commands allow monitoring swap space utilization.

To get a summary of total system swap space, use the swap command:

The output of the swap -s command shows the amount of swap space used (697504KB in this example) and available (95216KB), and further breaks down the used swap space into allocated and reserved. Allocated space represents swap space currently in use. Reserved space is in limbo, not available, not in use, but reserved for future use.

To get details on the individual devices or files that constitute the swap space, use:

The swapfile column is the device or filename of the swap component. The dev column shows the major and minor device numbers for devices or zeros for a file. Blocks is the total size of the swap component in 512 byte blocks (divide by two for KB) and free shows the number of 512 byte blocks unused.
