All, We had an issue with a DC where temps were elevated. The one bit of hardware that wasn't watched much was the one that sent out the initial alert. Looking for recommendations on hardware that I can mount/hang in each cabinet that is easy to set up and will alert us if temps go beyond a certain point. TIA. Dovid
Are you running ntpd on your boxes? See what happens when you plot its drift against other temperature sensors, the closer to the clock chip the better. If you do this on enough boxes, you should have an easy time seeing what happens on boxes where you have an easier time watching ntpd's drift value than you have watching a nearby dedicated temperature sensor. -- Harlan Stenn <stenn () nwtime org> http://networktimefoundation.org - be a member!
