David Jencks updated GERONIMO-4021:
-----------------------------------

    Fix Version/s:     (was: 2.2)
                   Wish List

I don't see anyone implementing this for 2.2.

If we base the monitoring group on muliticast pings then we could only query servers we were pinged by recently.

> Whenever the monitoring plugin attempts to monitor a server that is offline/doesn't exist, it takes way too long to load the page. We need to reduce this timeout period.
> I suggest that we add a parameter for the admin to set as the "timeout period" somewhere in the portlet. By default, we can choose to have this timeout parameter be set to 5000 milliseconds. 
> We can use the InetAddress class to call isReachable(int timeout) to see if the server is online.
