Distribution: official part of Check_MK

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.

Check parameters

Parameter	Type	Description
warning	int or float	the precentage of virtual memory used by processes at which WARNING state is triggered. If the level is defined as an integer value then it is interpreted as an absolute value in megabytes.
critical	int or float	the percentage or absolute value at which CRITICAL state is triggered

Performance data

Three variables: the physical RAM, the virtual memory and the sum of both.

Inventory
