memMinimumSwapX

Module: UCD-SNMP-MIB

OID (symbolic): UCD-SNMP-MIB::memMinimumSwapX

OID (numeric): 1.3.6.1.4.1.2021.4.23

Node type: OBJECT-TYPE

Type: CounterBasedGauge64

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 memMinimumSwapX?

This OID holds the minimum amount of swap space, in kilobytes, that should remain free during normal operation of this host. If memAvailSwapX falls below this configured minimum, the agent sets memSwapError and makes an explanatory message available in memSwapErrorMsg.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2021.4.23
snmpwalk -v2c -c public <target> UCD-SNMP-MIB::memMinimumSwapX

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2021.4.23.1
snmpget -v2c -c public <target> UCD-SNMP-MIB::memMinimumSwapX.1
