I’ve released a plugin, out of my latest project, that will notify you by SMS when there are errors on your server. It is the same idea as Jamis Buck’s excellent Exception Notifier plugin, but specially designed for SMS in the following ways:

• Messages are much shorter, making them more suitable for cell phones
• Messages are throttled so you don’t get too many
• It can be extended with alternative gateways

You can use it with both US-style email gateways, as well is Clickatell, a for-money gateway that can send to European-based cell phones. If you write other gateways, or have changes to the email one, which I haven’t actually tested in real use.

To install simply say:

script/plugin source http://svn.pinds.com/rails/plugins
script/plugin install exception_textable

See the README for more details.

Enjoy!
