Availability Metric definition

Question

What metric type/data do I need to define to have Oracle use it for it's "availability metric"? I've defined a simple target, but OEM can't find it's availability status. It reports "Availability metric not found for target ...."
Do I have to name it something specific, or is this a OEM configuration issue?

[oracle@oem ~]$ emcli add_mp_to_mpa
Error: The command name "add_mp_to_mpa" is not a recognized command.Oracle homeis set to OMS. Maybe that's the issue?
Well, my issue with the guide is, that I'm not totally sure on creating a report within OEM. I tried and it totally blew up on me. What would be really nice is an end-to-end example. Doesn't matter if it's "just" an OS command that's going to be interpreted; but the examples in the guide are incoherent and not related. And some are incomplete. It makes it hard to learn/understand. The missing reference manual doesn't make it better.
I know of the DTDs (why is Oracle still using DTDs and not using Schemas?) - however they don't explain COMPUTE_EXPR for instance (ie the expression language). And there's a lot of "holes" in explaining the different attributes and contexts. However, I've found the DTDs helpful through XML Spy because it will control what I can type where. Less error prune that way (I know, JDeveloper should be able to do that too, but it's too much work setting JDeveloper up for this stuff - and I don't even think JDeveloper will support DTDs at all to manage XML files).
I'm glad I have the latest version; but as you see I still seem to be quite lost ;) I've looked many times and I cannot find the section that talks about "availability" metrics?
I understand we can't have examples for everything - but a cohisive example through the guide would help. And a reference manual that goes into details with each attribute/element. If the DTD would have been complete there, it should be fairly easy to get the initial version going?
