My database server has some issues, that's why Drupal displays this message to every visitor:
"Unable to connect to database server
If you still have to install Drupal, proceed to the installation page.
If you have already finished installed Drupal, this either means that the username and password information in your settings.php file is incorrect or that we can't connect to the MySQL database server. This could mean your hosting provider's database server is down.
The MySQL error was: Too many connections.
Currently, the username is * and the database server is localhost.
* Are you sure you have the correct username and password?
* Are you sure that you have typed the correct hostname?
* Are you sure that the database server is running?
For more help, see the Installation and upgrading handbook. If you are unsure what these terms mean you should probably contact your hosting provider."
How to change this "public" message to something like "Site has some problems"?
Is there a reporting module that sends an email to the admin if the site has some serious issues like database not reachable?
