ZFS monitoring MIBs

Sun FM MIB

The Sun FM MIB (SUN-FM-MIB.mib) provides access to SUN Fault Manager information such as:

• Active problems on the system
• Fault Manager events
• Fault Manager configuration information

There are four main tables to read:

Sun FM MIB |.1.3.6.1.4.1.42.2.195.1.1 | Fault Management problems
Sun FM MIB |.1.3.6.1.4.1.42.2.195.1.2 | Fault Management fault events
Sun FM MIB |.1.3.6.1.4.1.42.2.195.1.3 | Fault Management module configuration
Sun FM MIB |.1.3.6.1.4.1.42.2.195.1.5 | Fault Management faulty resources

$ snmpwalk -v 2c serv1 .1.3.6.1.4.1.42.2.195.1.1

Sun AK MIB

The Sun AK MIB (SUN-AK-MIB.mib) provides the following information:

• Product description string and part number
• Appliance software version
• Appliance and chassis serial numbers
• Install, update and boot times
• Cluster state
• Share status (share name, size, used and available bytes)

There are three main tables to read:

Sun AK MIB | .1.3.6.1.4.1.42.2.225.1.4 | General appliance info
Sun AK MIB | .1.3.6.1.4.1.42.2.225.1.5 | Cluster status
Sun AK MIB | .1.3.6.1.4.1.42.2.225.1.6 | Share status

$ snmpwalk -v 2c serv1 .1.3.6.1.4.1.42.2.225.1.6

keep in mind that a reboot of a ZFS appliance will likely cause OID items in these ranges to be re-ordered each time. So if you are using a monitoring that tracks values based on fixed OIDs they will most likely end up with wrong values after a reboot!
