I have the below problem and need your suggesstion.

Problem :

My application is deployed in Websphere with 3 JVM instance( 3 ports).
I need to monitor the application in all 3 ports and if one goes down, i need to get alert.Goes down means, if the port is not accessible in any port or if the HTTP request (clickng hyperlink/button click) takes more time to reach other page via any port.

a) for checking the the application availabilty , i can check the http response status code 200.
b) but if the request takes longer to get response, it is a problem.
so, i need to know the response time for the http request made.
Based on this, if it is greater than certain seconds, i can set alerts.

How to get this response time for any http request we make ? any api in java or any other ideas . Kindly share.

If this was my problem I would use HttpClient to create a Java application that could poll the servers and track the response time.
HttpClient is part of the Apache Commons open source project.

It is sorta covered in the JavaRanch Style Guide.
