We attach a 5V power supply to one of the handshake lines on the server's parallel port, and run a little program that polls the I/O port. ]]> http://www.dslreports.com/forum/remark,22626191 Sun, 28 Jun 2009 23:10:02 EDT Re: Power loss notification by e-mail http://www.dslreports.com/forum/remark,22625359 battleop : We do something similar. We have a bunch of old Cisco 1900 switches. I put an IP in one and stick it at a site. If it goes down I remote into the router at that site and use "sh env all" and if one power supply is down then I know the power is out.]]> http://www.dslreports.com/forum/remark,22625359 Sun, 28 Jun 2009 19:58:36 EDT Re: Power loss notification by e-mail http://www.dslreports.com/forum/remark,22624473 TomS_ : If your UPS is half decent you should be able to connect it to the network, and poll certain OID(s) via SNMP to determine the state of the mains supply.

Or you may be able to use a script to "screen scrape" its web interface to pull out information if SNMP is not available, or the information is not easily locatable within SNMP.

I use both methods with some of my gear.

Otherwise, the canary idea is pretty much fool proof. If you can no longer ping it theres only a very limited number of things that can be wrong.]]> http://www.dslreports.com/forum/remark,22624473 Sun, 28 Jun 2009 15:59:29 EDT Re: Power loss notification by e-mail http://www.dslreports.com/forum/remark,22558176 public :

a ups monitoring pakage. look here »www.mikrotik.com/testdocs/ros/3.0/ha/ups.php
you can also send a mail ore sms via script if a ups alarm is detected.
Thats how i do it ...]]> http://www.dslreports.com/forum/remark,22557837 Tue, 16 Jun 2009 00:58:35 EDT Re: Power loss notification by e-mail http://www.dslreports.com/forum/remark,22557717 mejimbo :

We use something called a "Canary". It is a simple router, switch, or WiFi AP that you run at a site and you don't provide it with battery backup.

Ping it, until it quits and you know that there is no power at that site, if you can still ping the stuff on backup power.

We have a winner! So simple, but yet I didn't think of it... We already have a monitoring system that pings the network, adding this device will be easy. I try to make things to complicated sometimes. Thanks!]]> http://www.dslreports.com/forum/remark,22557717 Tue, 16 Jun 2009 00:20:00 EDT Re: Power loss notification by e-mail http://www.dslreports.com/forum/remark,22557624 prairiesky : I bought one, but it's been sitting on my shelf. It's called IP Power
They have a few different models. The one I purchased has 8 outputs and 8 inputs. It reads them and can email you upon a change.
I was going to take a 5V or so transformer plug it into the non UPS side. Then plug the device into the back up side. When the power goes out, that 5V goes to 0 and sends you an email. CAn be made pretty cheap, roughly 100 bucks plus you then have some controls through it to aswell as access through a web browser]]> http://www.dslreports.com/forum/remark,22557624 Mon, 15 Jun 2009 23:58:18 EDT Re: Power loss notification by e-mail http://www.dslreports.com/forum/remark,22557500 anon : ... all day at the base of a tower makes AnonDog AnOldDog...

It can be very basic, plug into a standard 110 power outlet and a network jack, configure the mail setting and when the power goes out send me an e-mail. Of course the network will continue to work when the power goes out "for a limited time" on batteries. This device could have it's on battery or a second AC plug "hooked to UPS bank" for power to send the message.

Does this exist? I want cheap and easy, nothing fancy.
