SQL App for Watchful
This App works with the Watchful service and lets you build simple SQL select query to check for custom values. If a new value has been found, you will be notified by email and an entry placed in your log files at watchful.net.
In addition, you can configure the notifications to be notfied based on a reference value, or if no reference value has been supplied the notification will be based on the previous check.
Simply install this App using the standard Joomla installer on every site that requires content notification, publish the app in the plugin manager. Be sure the site(s) on which you install this app has been added to your Watchful Dashboard and properly validated.
