Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.111.4.1.4.1.8 snmpwalk -v2c -c public <target> ORADB-MIB::oraDbLibraryCacheInvalidations
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.111.4.1.4.1.8.1 snmpget -v2c -c public <target> ORADB-MIB::oraDbLibraryCacheInvalidations.1
