[alcatel-nsp] Temperature monitoring in Nagios for ALU 7750 and 7450

[Jonathon Exley]

I have advice from the software fellows:


There's more than one OID for temperature.

In the table TIMETRA-CHASSIS-MIB::tmnxHwTable is a row for each managed component in the chassis. In this table are two columns of interest - TIMETRA-CHASSIS-MIB::tmnxHwTempSensor and TIMETRA-CHASSIS-MIB::tmnxHwTemperature. The value of tmnxHwTempSensor is true or false depending on whether a temperature sensor exists in the component or not, the value of tmnxHwTemperature is the temperature of the component in degrees celsius (or -1 if tmnxHwTempSensor is false).

Additionally there is a table TIMETRA-PORT-MIB::tmnxDigitalDiagMonitorTable that contains one row for each SFP/XFP that supports DDM. In this table is a column TIMETRA-PORT-MIB::tmnxDDMTemperature that contains the temperature of the SFP/XFP in degrees celsius.
