CRIU generates a set of stats-<type> files that contain statistics about how dump/restore went. These files are in google-protocol-buffers format, just like the images are, and can be viewed using the criu show -f [FILE] command.
Dump/Pre-dump stats
These are in stats-dump file. Fields are:
freezing_time- Time it took criu to freeze the process tree
frozen_time- Time tasks were in frozen state
memdump_time- Time criu spent grabbing required pages out of processes. This time does not include the next time
memwrite_time- Time criu spend transferring memory pages into image files (locally or on page-server)
All the above times are in microseconds.
pages_scanned- The number of pages criu looked at to decide whether or not to dump them
pages_skipped_parent- The number of pages criu skipped due to they were found in parent images (read about memory changes tracking)
pages_written- The total number of pages criu put into image files
