Our goal is to determine an overall "global" state for several subcomponent servers. Then we can let the user perform global operations that depend on that state. The difficulty is that we have a stateless system in the portlets that manage the servers, so we don't know what the last request to the servers was. We also allow users to interact with the servers via a command line, or through multiple portlets at the same time, so there could be things going on that we don't have control of from the portlet. Therefore we need to be able to determine the global state from the current states of the servers alone.
