[Xymon] State of the art SMS alerting?

[Mark Felder]

Our solution was to send the alerts to a script that formatted a message
nicely and uses the Pushover.net API. Pushover sends push notifications
to one or several mobile phones. This doesn't help if the internet is
down, but we're an ISP and have other ways of knowing if that specific
scenario were to happen.

We used to use the email-to-SMS gateways offered by providers but it's
foolish if email is down and we also found that those gateways were very
unreliable.
