Monitoring WebServer behind Reverse Proxy

Do you have an HTTP monitor configured? If not, you can configure one to perform an application layer check of the web servers. A typical send string would be:

 

 

GET /path/to/file HTTP\1.1\r\nHost: \r\nConnection: close\r\n

 

 

The receive string should be content that is only found when the application is up and responding correctly. As Deb pointed out recently, you shouldn't use 200 as this is often found in the Date header. HTTP would also be a bad option as it's included when the application sends any HTTP response code.
