The capture agent can merge settings defined in the local configuration manager
properties file with one hosted remotely. You have not configured a URL
specifying the remote configuration, so you get this WARN in the logs. This
isn't a problem. In fact, we should probably reduce that message from a WARN
to an INFO, since putting all of the configuration values in the local
configuration is perfectly legitimate, and this is the default configuration.
The fact that the matterhorn-capture-agent-impl bundle displays as "active" is
a good sign, it means that it started successfully.

The logs on the capture agents should provide you with more details. If you
want to increase the logging level, you can do so by changing
log4j.logger.org.opencastproject=INFO to log4j.logger.org.opencastproject=DEBUG
in $FELIX/conf/services/org.ops4j.pax.logging.properties

I definitely do not recommend taking this approach. If the debug logging is
still not sufficient to figure out what's happening, two tools come to mind to
help: wireshark, and the eclipse debugger. But I really think this is solvable
without diving that deep.
