memUsedSwapTXT
Module: UCD-SNMP-MIB
OID (symbolic): UCD-SNMP-MIB::memUsedSwapTXT
OID (numeric): 1.3.6.1.4.1.2021.4.16
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description:
The amount of swap space or virtual memory currently being used by text pages on this host.
This object will not be implemented on hosts where the underlying operating system does not distinguish text pages from other uses of swap space or virtual memory.
What is memUsedSwapTXT?
This OID holds the amount of swap space (disk-based virtual memory) currently occupied by executable code on the device. Swap usage indicates the device is under memory pressure and using slower disk storage instead of fast RAM. A system administrator would monitor this value to detect when a server needs more physical memory, since high swap usage causes significant performance degradation.
