Nut upsuser - Jun 2005 - upsmon/upssched on ups temperature

Hi All,
 I was wondering what people are doing to shutdown their equipment based
on the temperature NUT grabs from a UPS? It doesn't appear that
upsmon(8) has an appropriate notify event for temperature levels.

 For the time being, it looks like I'll write a simple perl wrapper
around upsc to get ups.temperature, but would love to use something
natively from NUT, if possible.

 Also, I'd like to say that NUT rocks. We are abusing it's flexibility
to get things done and it Just Works. Thanks developers!

Thanks!
 marco

it currently can't. The current notify system is "change" based,
which means that
if ups.status switch from OL to OB, you generate an ONBATT notification.
For non discrete values, the problem is to have a threshold to notify
upon sufficient change (ie if we wake up upssched every .1 =B0 change,
it will be borying...)

 for the moment, this is the best way: have a client that polls
 the desired values, and act upon your needs.

 In the future, when the asynchronous client pipe will be there,
 and the evolved upsmon/sched system with interpreted language [1],
 we will be able to do that easilly:
 if (ups.temperature > 50)
      upsmon -c FSD

 Note that the async pipe will allow to remove the polling.
 Your client will receive data that has changed...

 thanks for the thank in the name of all NUT developers and contributors.
