Log Room Converations caching & access

We have a Log Room Conversations option enabled on one of the older openfire servers (still 3.7.1). I do not see anywhere how long those are cached for or can’t figure out how to access them. We also have a Monitoring Service plugin installed although it is a bit old (1.2.0).

I saw in my search that the logs are probably in the local MySQL db but not sure how to connect to it since it is running on a linux server. Aslo, even if I connect to the DB, how to I view the logs (provided there isn’t a default purge setting someplace)?
