Description
According to https://mibs.observium.org/mib/A10-AX-MIB/ axSysHwFan1Speed, axSysHwFan2Speed and axSysHwFan3Speed are deprecated and instead axSysFanStatusTable should be used.
In my case axSysHwFan1Speed = Fan1, axSysHwFan2Speed = Not found, axSysHwFan3Speed = Fan2. This causes Fan3 to not be monitored and unfortunately Fan3 failed in one of the units which we didn't pick up as the fan isn't monitored by Observium
Improved in r13183.
