Correct. A node that crashed quickly (or where earlyoom killed something - I am looking at you, https://tracker.ceph.com/issues/48673 https://tracker.ceph.com/issues/48673) is visible only as a monitoring alert that goes away by itself, because all Ceph daemons are configured to be restarted after a crash by default. A slow/swapping node, on the other hand, leads to customer or end user complaints.
