This message is used to report information about the logging subsystem.
Note:
• The reported maximum log size will be smaller than that originally specified in LOG-
CREATE due to logging and filestore implementation overheads.
• Log entries are compressed in a variable length fashion, so it may be difficult to predict
log space usage with any precision.
• There may be times when the receiver does not have an accurate time (e.g. if the week
number is not yet known), in which case some entries will not have a timestamp. This
may result in the oldest/newest entry time values not taking account of these entries.
