[j-nsp] JunOS temperature readings

[Jimmy Stewpot]

Hello,

I am currently looking into an issue where we are getting temperature alerts on a variety of different JunOS devices within one of our facilities. Unfortunately when I go to track down the changes all the switches are running at under 40c which is within the thresholds yet we still get alerts.

I am interested to know if anyone has anything similar? Also is it possible to set the thresholds?
