I actually have most of this with Nagios. We are monitoring over 400 nodes with over 1200 services. I set up a soap perl script to create a ticket in our Numara Footprints support database. From there we use footprints escalations to email after 15minutes of downtime. and again after 1 hour. It will also email when the ticket is closed(host is back up). This allows us to do complex associates of users(say, bill gets all email issues, tom gets all issues at this location, etc). It also allows us to do some very complex reports and graphs using the footprints interface.

NASA Can't Pay for Killer Asteroid Hunt 398

Posted by Hemos on Tuesday March 06, 2007 @12:11PM from the anyone-raid-the-coffee-fund-money dept.

CGISecurity.com writes "NASA officials say the space agency is capable of finding nearly all the asteroids that might pose a devastating hit to Earth, but there isn't enough money to pay for the task so it won't get done. 'We know what to do, we just don't have the money,' said Simon 'Pete' Worden, director of NASA's Ames Research Center." But hey, it's just the potential end of the world, so nothing much to worry about there.

Submission + - Black Holes Discovered as Source of Gamma Rays

Objects like the Milky Way's central supermassive object (Sagittarius A*) are now suspected to be the culprit but since these are widely believed to be a black holes, little is known and skepticism is high that even gamma radiation could escape them. All that has been observed is gamma rays seem to coming from black holes. To test this theory, two scientists created a computer model and found that intense gravity near the event horizon caused protons to fling outward at near light speeds where some would randomly make it beyond 10 light years of the black hole after thousands of years. Once they are sufficiently far away, these super high-energy protons would collide with low-energy protons to form pions which decay into gamma radiation emanating in all directions from the collision. If their simulation holds to be accurate and survives the skepticism of the community, the source of some gamma rays that were believed to all be remnants of the big bang could instead be signals from just outside black holes. Not only does a rapidly rotating Wolf-Rayet star collapsing into a black hole cause narrow streams of gamma radiation but apparently they continue to emit them long after their formation."
