I’ve written a couple of plugins for the Mars Network Monitor, Mars is a small java application that allows you to monitor certain types of web-services (http/https/jdbc etc) and trigger alerts via emai/popup etc when a service cannot be contacted.
A couple of years ago I wrote a plugin to allow the notification of a problem to be sent via Jabber which was added to the release.
The new plugins are for notification of problems via AOL instant message or SMS message. A couple of people have asked for copies of the source on the Mars discussion forum so I have made them available here.
As with the Jabber stuff last year I’m happy for them to be included in the core Mars framework if they fit into the projects goals.
