+`object-reconstructor.partition.delete.count.<device>`  A count of partitions on <device> which were
+                                                        reconstructed and synced to another node because they

+                                                        per-device to allow for "quiescence detection" for
+                                                        object reconstruction activity on each device.
+`object-reconstructor.partition.delete.timing`          Timing data for partitions reconstructed and synced to
+                                                        another node because they didn't belong on this node.
+                                                        This metric is not tracked per device.
+`object-reconstructor.partition.update.count.<device>`  A count of partitions on <device> which were
+                                                        reconstructed and synced to another node, but also
+                                                        belong on this node. As with delete.count, this metric
+                                                        is tracked per-device.
+`object-reconstructor.partition.update.timing`          Timing data for partitions reconstructed which also
+                                                        belong on this node. This metric is not tracked

+`object-reconstructor.suffix.hashes`                    Count of suffix directories whose hash (of filenames)
+                                                        was recalculated.
