Options
| Name, shorthand | Default | Description |
|---|---|---|

Parent command
| Command | Description |

| docker system | Manage Docker |
Related commands
| Command | Description |
|---|---|
| docker system df | Show docker disk usage |
| docker system events | Get real time events from the server |
| docker system info | Display system-wide information |
| docker system prune | Remove unused data |
Extended description
Get event information from the Docker daemon. Information can include historical information and real-time information.
Docker containers will report the following events:
attach, commit, copy, create, destroy, detach, die, exec_create, exec_detach, exec_start, export, kill, oom, pause, rename, resize, restart, start, stop, top, unpause, update
Docker images report the following events:
delete, import, load, pull, push, save, tag, untag
Docker volumes report the following events:
create, mount, unmount, destroy
Docker networks report the following events:
create, connect, disconnect, destroy
OPTIONS
The --since and --until parameters can be Unix timestamps, date formatted
timestamps, or Go duration strings (e.g. 10m, 1h30m) computed
relative to the client machine’s time. If you do not provide the --since option,
the command returns only new and/or live events. Supported formats for date
formatted time stamps include RFC3339Nano, RFC3339, 2006-01-02T15:04:05,
2006-01-02T15:04:05.999999999, 2006-01-02Z07:00, and 2006-01-02. The local
timezone on the client will be used if you do not provide either a Z or a
+-00:00 timezone offset at the end of the timestamp. When providing Unix
timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
fraction of a second no more than nine digits long.
EXAMPLES
Listening for Docker events
After running docker events a container 786d698004576 is started and stopped (The container name has been shortened in the output below):
# docker events
2015-01-28T20:21:31.000000000-08:00 59211849bc10: (from whenry/testimage:latest) start
2015-01-28T20:21:31.000000000-08:00 59211849bc10: (from whenry/testimage:latest) die
2015-01-28T20:21:32.000000000-08:00 59211849bc10: (from whenry/testimage:latest) stop
Listening for events since a given date
Again the output container IDs have been shortened for the purposes of this document:
# docker events --since '2015-01-28'
2015-01-28T20:25:38.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) create

2015-01-28T20:25:39.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) start
2015-01-28T20:25:40.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) die
2015-01-28T20:25:42.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) stop
2015-01-28T20:25:45.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) start
2015-01-28T20:25:45.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) die
2015-01-28T20:25:46.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) stop
The following example outputs all events that were generated in the last 3 minutes, relative to the current time on the client machine:
# docker events --since '3m'
2015-05-12T11:51:30.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) die
2015-05-12T15:52:12.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) stop
2015-05-12T15:53:45.999999999Z07:00 7805c1d35632: (from redis:2.8) die
2015-05-12T15:54:03.999999999Z07:00 7805c1d35632: (from redis:2.8) stop
If you do not provide the –since option, the command returns only new and/or live events.
