Mail your Errors during development without Nagios/Ossec

stdInMailer.php

<?php

// during development you can simply have all Error mentions in your logs (presumably you are logging properly?) mailed to you.
// in production you may be using OSSEC/Nagios etc, but this is a quick win for dev.

// to run, you would do something like
// tail -f /var/log/messages |grep Error | php /home/sites/poc/stdInMailer.php

$fp = fopen("php://stdin","r");

while ($line = stream_get_line($fp,65535,"\n"))
{
    // output as if normal tail were in flow
    echo $line."\n";
    // send the mail
    mail('[email protected]', 'Dev Container Error Mail', $line);
}
fclose($fp);

// alternatively you can do this inline...

tail -f /var/log/messages | grep Error | php -R 'mail("[email protected]", "Dev Container Error Mail", $argn);'

// take your pick.
