The vmem plugin collects information about the virtual memory subsystem of the kernel. Per default, information such as page-faults, page-in and page-out to and from memory and swap, and the total number of pages are collected. When verbose statistics are enabled, all page actions (allocations, refills, steals, …) are collected per zone (DMA, DMA32, …).

See this section in the full configuration reference

The vmem plugin collects information about the usage of virtual memory. Since the statistics provided by the Linux kernel are very detailed, they are collected very detailed. However, to get all the details, you have to switch them on manually. Most people just want an overview over, such as the number of pages read from swap space.

Verbose true|false: Enables verbose collection of information. This will start collecting page "actions", e. g. page allocations, (de)activations, steals and so on. Part of these statistics are collected on a "per zone" basis.
