cpqOsMemAvailableKBytes
Module: CPQOS-MIB
OID (symbolic): CPQOS-MIB::cpqOsMemAvailableKBytes
OID (numeric): 1.3.6.1.4.1.232.19.2.4.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Available Bytes is the amount of physical memory available to processes running on the computer, in bytes. It is calculated by summing space on the Zeroed, Free, and Standby memory lists. Free memory is ready for use; Zeroed memory is pages of memory filled with zeros to prevent later processes from seeing data used by a previous process. Standby memory is memory removed from a process's working set (its physical memory) on route to disk, but is still available to be recalled.
What is cpqOsMemAvailableKBytes?
This read-only integer reports the amount of physical memory, in kilobytes, currently available to processes, calculated as the sum of the Zeroed, Free, and Standby memory lists. An admin watches this to catch memory exhaustion before it forces excessive paging or causes allocation failures. For example, cpqOsMemAvailableKBytes trending steadily downward over time on a server would warn of a memory leak in a running application.
