During the last trainings a few questions popped up which were not be answered by the documentation:

• If a conflicting transaction (wsrep_retry_autocommit) is happening, is one of the counters wsrep_local_bf_aborts and wsrep_local_cert_failures increased or not?
• If yes: Which one?
• If no: Feature request: Counter for how many retries we had since server restart.
