memMinimumSwap
Module: UCD-SNMP-MIB
OID (symbolic): UCD-SNMP-MIB::memMinimumSwap
OID (numeric): 1.3.6.1.4.1.2021.4.12
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description:
The minimum amount of swap space expected to be kept free or available during normal operation of this host.
If this value (as reported by 'memAvailSwap(4)') falls below the specified level, then 'memSwapError(100)' will be set to 1 and an error message made available via 'memSwapErrorMsg(101)'.
What is memMinimumSwap?
This object defines the minimum threshold of free swap memory that should be maintained on a system during normal operation, measured in kilobytes. If the available swap space (as reported by memAvailSwap) falls below this threshold, the agent triggers an error flag (memSwapError) and generates an error message. System administrators use this to monitor and alert on critically low swap space conditions that could impact system performance.
