[c-nsp] temperature reading GSR

[John van Oppen]

Also worth noting that graphing them with SNMP is also useful to
identify long-term trends.   I realized we had people putting stuff in a
rack next to us backwards (ie hot output into the cold isle) once that
way.

Both.  High temps at the inlet indicate insufficient cold air.  High 
temps at the hot sensor indicate poor airflow - think airflow 
restrictions, failed fans, etc.

Consider using SNMP to track these.  You should then be able to pull the

warning and critical thresholds on a per-card basis to know when you're 
running hot.
