+**MonitoLite** is a very simple monitoring tool developed in Perl. It supports : 
+ * **ping monitoring**: sends a `ping` command to the specified host. Raises an alert if the host is down
+ * **http monitoring**: gets the provided URL and raises an alert if the URL returns an error. Optionally you may specify a string to search on the page using the `param` database field. It raises an alert if the specified text could not be found on the page.
  
+ In case of an alert, the script sends an email notifications to the specified contacts (one or many). 
+ The script also sends a recovery email notification when the alert is over.
+
 It uses a SQL backend for handling the tasks and the status of the tasks. 
 Tested on MySQL only.
