Ah, good catch.

Just check that the daemon is running and log/database files exist.  For a
non-broken system, the sqlite database will just contain a few empty tables and
the logs will just notify you that the various monitors are active:

    $ herd status rasdaemon
    $ pgrep -a rasdaemon
    $ cat /var/log/rasdaemon
    $ sqlite3 /var/lib/rasdaemon/ras-mc_event.db

I honestly don't know a lot about RAS, yet, so that's the extent of what I can
easily probe.
