Added optional container restore statistics
This adds the parameter '--print-stats' to 'podman container restore'. With '--print-stats' Podman will measure how long Podman itself, the OCI runtime and CRIU requires to restore a checkpoint and print out these information. CRIU already creates process restore statistics which are just read in addition to the added measurements. In contrast to just printing out the ID of the restored container, Podman will now print out JSON: # podman container restore --latest --print-stats { "podman_restore_duration": 305871, "container_statistics": [ { "Id": "47b02e1d474b5d5fe917825e91ac653efa757c91e5a81a368d771a78f6b5ed20", "runtime_restore_duration": 140614, "criu_statistics": { "forking_time": 5, "restore_time": 67672, "pages_restored": 14 } } ] } The output contains 'podman_restore_duration' which contains the number of microseconds Podman required to restore the checkpoint. The output also includes 'runtime_restore_duration' which is the time the runtime needed to restore that specific container. Each container also includes 'criu_statistics' which displays the timing information collected by CRIU. Signed-off-by: Adrian Reber <areber@redhat.com>
