What is extIndex?
This string value provides a row number or reference identifier for a particular extensible script entry in the UCD SNMP agent. It serves as an index to uniquely identify monitoring scripts being executed. A system administrator uses this when querying script execution logs to correlate results with specific monitoring definitions.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2021.8.1.1 snmpwalk -v2c -c public <target> UCD-SNMP-MIB::extIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2021.8.1.1.1 snmpget -v2c -c public <target> UCD-SNMP-MIB::extIndex.1
