Jeffro Posted March 25, 2011 Share Posted March 25, 2011 I have a couple hundred websites that I run a php/mysql script on. Every couple weeks, I manually visit every site to ensure it's up and running. Without fail, there's always one or two that have a message indicating the database has crashed. I run some pretty big cron jobs on them every night.. so it just happens. Can someone recommend a way that I could poll all of my mysql databases and somehow email/alert me when one goes down? Thoughts? Thank you. Quote Link to comment https://forums.phpfreaks.com/topic/231703-email-script-to-check-for-a-downed-database/ Share on other sites More sharing options...
blacknight Posted March 31, 2011 Share Posted March 31, 2011 something like this? <?php echo '<html><head></head><body>'; //check function $messages = 'Database check Return<br> '; function chk_db( $dbhost, $dbname, $dbuser, $dbpass, $prefix='' ) { global $messages; $prefix = $prefix; $dbname = $dbname; if( empty($dbpass) ) { $link_id = @mysql_connect($dbhost, $dbuser); } else { $link_id = @mysql_connect($dbhost, $dbuser, $dbpass); } @mysql_query("SET NAMES 'utf8'"); if( (is_resource($link_id)) && (!is_null($link_id)) && ($dbname != '') ) { if( !@mysql_select_db($dbname, $link_id) ) { @mysql_close($link_id); $table = '( <span style="color:ff0000">DB named '.$dbname.' failed to connect</span> )'; } $messages .= '<span style="color:99ff33">DB '.$dbhost.' Connected '.$table.'</span><br>'; } else { $messages .= '<span style="color:ff0000">DB '.$dbhost.' ('.$dbname.') failed to connect</span><br>'; } return true; } # # now creat an array with the mysql info # for all the databases you need to check... # $array = array( array( 'dbhost' => 'localhost', 'dbuser' => 'root', 'dbname' => 'wowroster', 'dbpass' => '', 'prefix' => '', ), array( 'dbhost' => 'localhost', 'dbuser' => 'root', 'dbname' => 'avg', 'dbpass' => '', 'prefix' => '', ), array( 'dbhost' => 'localhost2', 'dbuser' => 'XXX2', 'dbname' => 'XXXXX2', 'dbpass' => '', 'prefix' => 'blah_2', ), array( 'dbhost' => 'localhost3', 'dbuser' => 'XXX3', 'dbname' => 'XXXXX3', 'dbpass' => '', 'prefix' => 'blah_3', ), ); # # then loop the array to check the databases # and set it so that if one returns false we get a warning... # foreach ($array as $host => $h) { $x = chk_db( $h['dbhost'], $h['dbname'], $h['dbuser'], $h['dbpass'], $h['prefix']); } echo $messages; $message = wordwrap($messages, 70); // Send mail('caffeinated@example.com', 'Db Status', $message); this prints it to the screen and emails a copy as well... also will say if the database in the host is active or not... hope this helps...

Jeffro Posted April 4, 2011 Author Share Posted April 4, 2011 Thanks for the script! It looks promising. I'll give it a go later in the week and see if it does trick. Much appreciated!
