Now positive exactly what you are asking here. do you mean you need to know where the edb and log files are for the databases in your Dag? If so, run get-mailboxdatabase -Identity <name of Database> | fl. Look for edbfilepath and logfolderpath.  You don't need to specify the server in this, only the name of the Database since all copies of a database in a Dag need to use the same paths on each server. If you are trying to see where Circular logging is enabled, use the EAC/EMS depending on the version of Exchange

does circular logging run every minute
Jeff GloverSr. Systems AdministratorCommented:
Circular logging is not a service per se but how the database treats log files. If you have it enabled, when the log file drives run out of space, it starts overwriting the oldest ones. If you are backing up your database somehow, then a full or incremental backup should commit the log files and truncate them. If you aren't, then you would need circular logging enabled or you will run out of space and dismount the database. However, my personal recommendation from experience is to backup the database if possible. Methods such as lagged copies for Fault tolerance need higher amounts of attention.
  Best practice is to put the logs and databases on different drives if possible. If you leave them on the C: drive where the end up by default if you don't specify a location, then you can easily run your server out of space.
