Hi, all.
This is Austin.
I've been trying to understand how the inventory in agent works.
As far as I understand, an inventory is a graph, and the agent sends the
graph to the hawkular server with some kind of format. Such that the
hawkular server can answer queries with the data that the agent sends.
I have a few of questions:
1. What are the various protocols for(dmr, jmx, platform)?
2. And there's Resource and ResourceType, each of them holds a graph,
what's the relation between them? Are they isomorphic and each node of
ResouceType annotates the corresponding Resource node?
Thanks!

Hey,
1. What are the various protocols for(dmr, jmx, platform)?
That is mostly on how to obtain the data. Dmr is some
Wildlfy-internal protocol, that is detyped and can be
accessed from external with some sort of rest-api.
Jmx are the java management extensions and can be
used to talk to remote java vms and obtain management
information from there.
2. And there's Resource and ResourceType, each of them holds a
graph,
what's the relation between them? Are they isomorphic and each node of
ResouceType annotates the corresponding Resource node?
No. It is rather the relation of class (=ResourceType) and
its instantiated object (=Resource). Check e.g. the Datasources
where you have one ResourceType "DataSource" and multiple
datasources of this type like HawkularDS and KeycloakDS

Yes, the various protocols are ways how the Agent is able to both
discover resources and also collect metrics about them.

Many thanks to Heiko for giving such a clear example of classes and objects
and Peter for elaboration. :)

In case you haven't found it already, hawkular.org contains a little bit
of documentation on various types of entities inventory understands and
how they are organized:
