Distribution	official part of Check_MK
License	GPL
Supported Agents	SNMP

This check measures the usage of physical RAM and virtual memory using the HOST-RESOURCES-MIB, which is provided by many SNMP agents (especially those on standard operating systems).

The logic used for monitoring is exactly the same as in the agent based check mem.used. Please refer to the man page of that check for details.
