To start with we would like to monitor a subset of the information that is available from the Enterprise Manager console, such as a list of the instances (infrastructure, midtier(s)) and the oracle home for each instance, as well as the components deployed on each instance (http server, oid, j2ee applications) and optionally their cpu and memory usage.
We are also learning the HQ architecture and have deployed a very simple oas plug-in based on the oracle database server plug-in. So far all it does is check for the existence of the app server using the /etc/oratab home directories and the presence of a j2ee sub-directory. One question that we have regarding this is that our oas plug-in tests out ok using the command-line "-m discover" switch, but since we're new to HQ we're not sure how to have HQ invoke the runtime auto-discovery on it's own so the oas server is added to the list available in the dashboard. Any help on configuring this would be greatly appreciated.
