Can any one let me know the difference between the actual memory and
physical memory which is being monitored by hobbit?
It depends on the OS. But the basic is: physical is the memory in the box.
Actual is the memory in use by programs.
Total physical memory = program in physical memory + cache + free memory
Actual = program in memory + program in swap
Total physical memory will be 100% because the disk cache will consume all
available memory.

Thank you!

On our Linux (5.1) hosts the memory page (Xymon 4.2.3) reports three values: Actual, physical, and swap. What do the Actual and Physical numbers refer to? The man page for hobbit-clients.cfg doesn't say.
