What is numBytesFree?
This reports the number of bytes currently free in system memory on the target. Admins watch this over time to catch a memory leak before the device runs out of heap space.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5812.1.5.1 snmpwalk -v2c -c public <target> DEVICE-MIB::numBytesFree
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5812.1.5.1.1 snmpget -v2c -c public <target> DEVICE-MIB::numBytesFree.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> numBytesFree.1
