Description: The number of bytes free in the system memory
What is numBytesFree?
This reports the number of bytes currently free in the VxWorks system memory pool on this device. An admin polls this to watch for memory exhaustion, since a value that keeps shrinking over time can indicate a memory leak in the running system.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5651.3.20.1.1.1.1 snmpwalk -v2c -c public <target> MPIOS-MIB::numBytesFree
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5651.3.20.1.1.1.1.1 snmpget -v2c -c public <target> MPIOS-MIB::numBytesFree.1
