We've got a lot of those, too.  But now we are rolling out Weathergoose
from ITwatchdogs.  The uptimedevices probes tend to get stuck and report
a constant temperature, or just die for no apparent reason.  And we got
a case of them that just didn't work for beans.  So, when we find a dead
uptime, we replace it with a weathergoose.

I have about 80 locations with monitors, mainly to spot dead air
conditioners in the tin shacks we have dotted around the city.
