I wonder if it's worth leaving a changelog note on this as an improvement to the DB engine.

Does the mount_accessor not work for identifying the backend? That is included in the logs but maybe it isn't as human friendly?

EDIT: mount_accessor would not help to identify what database config and role failed rotation

[fairclothjm]

Should we initialize the logger with hclog.With() https://github.com/hashicorp/go-hclog/blob/f7ed9e449c8dc3102bfcb86a8bda2855e07645b8/logger.go#L190 so that all logs are consistent and we don't have to worry about missing this if we add log lines in the future?

@calvn - Thanks, will add the changelog entry.

@fairclothjm - Good idea. Let me see on the logger.

@fairclothjm - Change to use hclog.With() in e544f01. Good suggestion, that cleaned up nicely.
