Monitoing a Reverse Proxy and Weblogic Servers

We have Reverse proxy that intercepts requests.

 

 

we must monitor that the webserver is receiving requests and that the weblogic portal server is receiving requests. If either of them in the pair fail the monitor should redirect to the other pair.

 

 

This is important because the webserver can be up and running and properly reverse proxy to the WLP server, but if the WLP server is not accepting requests properly we don't want to forward requests there. (if we are only monitoring Webserver and it passes, but the WLP server is down it will continue to fail for users).

 

 

Oppositely, if the monitor is only checking WLP and not the reverse proxy, it could pass because WLP is running but the Sun Webserver is down giving users a 404).

 

 

Can I accomplish this with an Irule or is this a simple configuration?

    Depends on which pieces you're load balancing.

     

     

    Sounds like you're load balancing the webserver tier only of a silo configuration (each webserver fronts a specific portal instance, webserver + portal pair = silo).

     

     

    If that's the case, then you'll just want to create a monitor that reaches through the web tier to retrieve some content that only a successful query to the portal server could retrieve. That way, if either the webserver or the portal server are not responding as expected, the webserver would be marked DOWN and the other webserver/portal silo would get the traffic.
