259 $ swift-dispersion-report --container-only
260 Queried 2621 containers for dispersion reporting, 17s, 0 retries
261 100.00% of container copies found (7863 of 7863)
262 Sample represents 1.00% of the container partition space
263
264 $ swift-dispersion-report --object-only
265 Queried 2619 objects for dispersion reporting, 7s, 0 retries
266 100.00% of object copies found (7857 of 7857)
267 Sample represents 1.00% of the object partition space
