How to monitor TOMCAT AJP port

 

The setp up we have: HTTPS Request > Web server (APACHE)> Firewall>F5 Load Balancer> Application server (TOMCAT> UROUTER Middleware service) > Database (Oracle). I would like to configure Monitors for Application Pool (TOMCAT). This document (http://www.f5.com/pdf/deployment-guides/tomcat-dg.pdf) suggest to use this string (GET /bookstore/healtcheck.jsp HTTP/1.0\r\n\r\n). However, we do not have an option to use JSP file on Application (TOMCAT) server. Are there any otherways to Monitor TOMCAT (AJP)? Thank you.

    The details in the guide are simply examples, simply change the request URI (from /bookstore/healtcheck.jsp) to something valid in your environment.

    Thanks for your suggestion. This is an Application server and listening on TOMCAT AJP port so none of the GET command works for valid URL. i.e http://FQDN:TMOCATAJPPORT/test/test.com

    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.
