Overview

SNMP memory and swap utilization checks.

Set ‘usage’ and ‘available’ keys as properties, in percentage/GBs, respectively.

By default, doesn’t warn on memory usage, only swap, since that’s more indicitive of a problem. You can still set the ‘physical_warn_at’ key to force warnings on ram usage, for embedded systems or other similar things without virtual memory.
