Set your Error Document directive: http://httpd.apache.org/docs/2.0/mod/core.html#errordocument ErrorDocument 404 /place/mailer.php ErrorDocument 406 /place/mailer.php ErrorDocument 500 /place/mailer.php ErrorDocument 501 /place/mailer.phpIn mailer.php, or whatever scripting language you chose to use, you will have code that sends an email. I would be careful, this can get a little out of hand, and you will get a lot of emails.
I may be inclined to do something like this: (pseudo code) no_mail_arr = array('google', 'bing', etc etc etc) if (user_agent not in array) $message = the headers + the page name + the url + the agent + referrer mail(someone@xxxxxxxxxxx 'error on page $page', $message) end ifIn reality, I think it would be better to just set up a custom logging directive, and log any http you desire, to a special log, with all the data you need. Run that log through any good stats software, and you will be much better off.

Please advise on how can we monitor HTTP Error Codes on a web server and then send an email alert upon errors.The HTTP Error Codes we need alerts on are 404,406,500 and 501 errorsWe do not want to monitor it for a particular site, but serverwide. So we need to find some way to pull the details from apache error log ( /etc/httpd/logs/error_log
