What is diskIOIndex?
This read-only object is the index identifying a specific monitored disk device in the diskIOTable. Admins use it to correlate a given disk's I/O statistics, bytes, accesses, load, busy time, across the various columns of the table. A row with diskIOIndex of 0 typically corresponds to the first monitored disk device, such as /dev/sda on a Linux host.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2021.13.15.1.1.1 snmpwalk -v2c -c public <target> UCD-DISKIO-MIB::diskIOIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2021.13.15.1.1.1.1 snmpget -v2c -c public <target> UCD-DISKIO-MIB::diskIOIndex.1
