Whether we embed C* in -services or in another distro, either way, we have a problem.
I'm sure all of us have seen this at one time or another :)
It seems if I restart the server, …
[View More]most times (not all) I no longer see these errors. I have no idea if this is just going to cause problems in alerts, or if there are other problems we'll see. But I see lots of these kinds of errors:

I see several of these inventory warnings in my agent itests - all my tests pass, so its not causing any problems that I can see. But just wanted to point it out. Seems to happen at startup?

List of endpoints in components
by Lukas Krejci
Due to a bug in the listing of endpoints in inventory (something I never
really paid attention to, because it seemed like this was autogenerated from
Resteasy metadata) I started thinking about what is actually returned from
that endpoint.
The format is somewhat spartan:
[{"uri": "...", "methods": ["GET", "POST", ...]}, ...]
Now during the build, all the Hawkular components use something much more
complete and elaborate - the swagger.json - which we use to generate the API
documentation …
[View More]for hawkular.org.
I think it would be much better if the endpoint listing actually returned the
swagger.json instead of the above format lacking much of the information
available in swagger.
What do you think?
This would obviously break the current users but would be much more helpful
for API consumers given the richness of the swagger format and the amount of
information we include.
