That's something that we may be able to sort out, so, yes, perhaps this
is an option that might work...

A lot of data may be written every day, but a daily check should still
find the disk close to being full, relatively speaking, if there is a
risk of filling up the disk. As in, one issue on the system in question
is that it has log files that can grow by a few gigabytes every day, but
that's still not a lot compared to the total disk space. (The logs are
subject to rotation, but problems may occur because new logs file are
larger than the ones "rotated out". And we want to keep log data for as
log as we can.)
So, yeah, maybe we can work with logwatch. Looking at an old root
mailbox file, I don't see any "direct" warnings related to disk space,
but I do find a number of lines like
Warning: Audit daemon is low on disk space for logging: 1 times
Do you expect something in the "Disk Space Begin" ... "Disk Space End"
section, too?
