monitoring 500 error

[pradhanparas]

How does one monitors apache 500 error and Internal server errors. I can check if apache is on or off but not sure how to monitor 500 and similar errors when the port 80 is up and running.

How do you guys handle this?

-Thanks

I´ve not done this specific case myself yet but you could create a script that runs a curl towards your page and parse the http response code, then just print/echo it in the end of the script.

Then add a row in your agentd conf file:
UserParameter=http.status,/path/to/script/check_status.php

Add item in Zabbix.
Item type: Zabbix Agent
Key: http.status

Sample curl test in php (I´ve verified the code):

#!/usr/bin/php
<?php
$url = "http://www.yoursite.net/index.php";

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url );
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($curl);

if(empty($result))
{
  // fatal error, log error
}
else
{
  $info = curl_getinfo($curl);
  curl_close($curl);

  if(empty($info['http_code']))
  {
     // no http response code received, log error
  }
  else
  {
     // http responce code received.
     echo $info['http_code'];
  }
}
?>

With the response code you can easily produce triggers.
This should get you started with the task.
