You can see in the console only warnings and errors logged by SCR by just setting the "equinox.ds.print" property to "true" and "equinox.ds.debug" to "false". You will see errors that occur in the activities of SCR like processing component descriptions, calling activate/deactivate and bind/unbind methods of components, etc. You will probably not see error in case any service reference is not resolved unless it is caused by a bad component description.
Your suggestion about console commads interacting with SCR is very interesting and might help a user to investigate problems with his/her components. But unfortunately there are no console commands for that purpose. Can you please open a bug about that?

It's worth noting that the flags didn't seem to be in the latest official release (3.3.2). I had downloaded the 3.4M6a milestone build, though, and got the output you described. Regarding that output, though, I still wasn't able to easily detect the kind of error I frequently run into. The scenario is generally like: Service A references many services (B, C, and D, etc.) all with 1..1 cardinality. Somewhere along the way I figure out that Service A is not activating, but I have no idea which reference is not being resolved (Let's say it's B). So, what I notice are statements like "DEBUG ## Resolver.resolveEligible(): reference 'Service B' of component 'Service A' is not resolved" that show up in many places as the Resolver attempts to do its work. However, these messages are at a DEBUG level, and there are a lot of them. Additionally, I suppose you could say that B may be just about to be introduced, so it's not really concerning that it doesn't exist yet. At any rate, there's a lot of noise to sort through to try to understand why Service A is not present. So I am wondering if you have any other suggestions for how to quickly identify this kind of problem? Might there be console commands that can interact with the SCR to list services that are left unactivated due to unresolved references? If not, would it be a plausible thing for me to write?

If you turn on only the equinox.ds.debug property, the debug messages will be sent only to the LogService if available.

Is there debug output from the SCR that I could be taking advantage of to help this process? If so, what combination of bundles and settings are required to see it?
