<br><font size=2 face="sans-serif">Greetings NUT users,</font>
<br>
<br><font size=2 face="sans-serif">I am looking for a solution to monitor
the power OUTSIDE my datacenter. (The on/blackout status of main
building power). </font>
<br>
<br><font size=2 face="sans-serif">My small datacenter is covered by a
UPS, an older Liebert 18Kva unit with no environmental or status monitoring
outside of the LCD console and audible alarm. The Liebert UPS is
backed by a 35KW diesel generator which usually kicks on within 10 seconds
of a power outage. The generator has a ~36hour runtime. (Air
conditioning of the datacenter is also generator backed).</font>
<br>
<br><font size=2 face="sans-serif">This solution is great for the needs
of the datacenter for most conditions, but I still would like to know when
power in my building goes out so I know if the outage is long enough for
me to need to come on site shut non-critical systems down or monitor generator
fuel levels. </font>
<br>
<br><font size=2 face="sans-serif">What I am looking to accomplish is setting
up a cheap pollable UPS that can report online or no incoming power status.
Which will then be used by Nagios to send off an alert. The only
load on the UPS will be a clock or something very low power like an LED
light. </font>
<br>
<br><font size=2 face="sans-serif">Yes, it is a hack... but it's a simple
hack, and they have saved me more times than not. </font>
<br>
<br><font size=2 face="sans-serif">What would be the cheapest UPS unit
that NUT, or other apps can poll to check good vs no power status?
I was looking at the PowerWare 3105, though it's a beta driver. For
$40, it seems like it would be a good starting point. If the solution
becomes too expensive, Ill just end up putting a longlife lightbulb on
building power and pointing a webcam at it. </font>
<br>
<br><font size=2 face="sans-serif">Anyone have any sample output of this
or other UPS unit? Or any other ideas for this sort of monitoring?</font>
<br>
<br>
<br><font size=2 face="sans-serif">Thanks,</font>
