How to monitor TOMCAT AJP port

I'm not sure how or why the deployment guide would suggest an HTTP test for AJP. They must be assuming an HTTP server front-end, I suppose?

I think you should create a new TCP test using the ping command from the AJP specification. You would transmit and expect the following hexadecimal-formatted data:

Transmit (AJP ping): \x12\x34\x00\x01\x0A

Expected response (AJP pong): \x41\x42\x00\x01\x09

I hope this proves helpful.
