OpenBSD Xuvmstat

I found a virtual memory monitoring tool in the port, with it I have more clear view of how actually system memory works. The UVM virtual memory system manages access to the computer's memory resources. User processes and the kernel access these resources through UVM's external interface. By the way there's great documenetation out there that really helps me a lot in order to understand it, you should check it out here even though it is more on NetBSD system.

You can also find the man page useful especially uvm and vmstat in this case.

Xuvmstat shows the memory statistics in kernel
