Health Check Page

This page will explain how to make a health check page where HAProxy is used to check the status for each one of our platforms.

Ruby on Rails/Mongrel

Copy mongrel_health_check.rb (attached below) into your server or svn
Add "config_script: /path/to/file" to /etc/mongrel_cluster/mongrel_cluster.yml
Set OPT_HEALTH_CHECK_URI to "/mongrel-status"

Tomcat

Create a file named health_check.jsp in your application with the following contents.

<HTML>
 <HEAD>
  <TITLE>Hello World</TITLE>
 </HEAD>
 <BODY>
  <H1>Hello World</H1>
  Today is: <%= new java.util.Date().toString() %>
 </BODY>
</HTML>

Set OPT_HEALTH_CHECK_URI to "/health_check.jsp"

PHP

Create a file named health_check.php in your application with the following contents.
```
<?php
phpinfo():
?>
```
Set OPT_HEALTH_CHECK_URI to "/health_check.php"

HAProxy

If your sit'e permissions allow it, you can simply add 'haproxy-status' to your domain to check the status of HAProxy.
ex: http://www.mysite.com/haproxy-status
