gnocchi-statsd errors out ugly when lacking config

[Chris Dent]

If you try to start gnocchi-statsd without config settings it will produce confusions exceptions (for instance since it has no resource id there will be an exception from sqla).

The conf settings that statsd wants are:

                'resource_id',
                'user_id',
                'project_id',
                'archive_policy_name',
                'flush_delay',

None of these have defaults. flush_delay could presumably have a default.

We should probably error out with a nice message when there are no defaults for the rest of them so that the initiator has some idea of what to do to fix the problem.

You can set them to mandatory=True with oslo.config. I think I did that but it forced people to configure that even if they were not using statsd.

[Chris Dent (cdent)]

Yeah, I think it is going to have to be in the statsd code itself: pseudo:

if resource_id is None:
    send a friendly message
if something else is None:
   send some other friendly message
