As a side note, MongoDB offers a "capped collection" mechanism with the semantics that you can insert rows at will, and it rolls around automatically by replacing oldest entries with the newest ones. This tends to be a very convenient way to do structured logging, both on the writing and on the reading side. Using that as a general rsyslog might be unwise, as there are a number of details to get right and the volume may get wild depending on the application, but at least for the juju implementation itself it might be quite convenient. Imagine being able to ask "please tell me the output of the last run of the db-relation-joined hook on unit db/3".
