d058e63ad3 remove images with size 0 
To narrow the list of volumes to be shown in munin, all the small
volumes with size "0B" are not shown.
As size 0B is not relevant as volumesize, this these volumes add no
additional information.

c633ff00ea docker_: ignore contains which are not running 
Some containers may be in "restarting" state.  We should ignore these.

Thanks, ogmueller!

51af0be02b docker_: sanitize value container names 
docker_ plugin sanitized container names when printing config but
not values which led to a disparity resulting in no data on graphs
for all containers whose names are subject to sanitization. (#1212)

7ac850853d Plugin docker_: reduce permissions of plugin 
root privileges are not required for sending queries to the docker socket.
Instead the group "docker" should be sufficient.

Additionally replace /var/run with /run (following updates of FHS).

109144ded5 [docker_] Get CPU count from os.cpu_count() everywhere 
Docker-py and os.cpu_count() disagree on the count, leading to data
going beyond the scale of the graph. As Docker-py seems to have dummy
CPU data in the stats, we instead always rely on Python's CPU count.

[plugin/docker_] Improvements to docker_ plugin (#1094) 
* Add support for docker_network
* Actually show non running containers counts
* Show intermediate and dangling images counts
* Add warnings on dangling images and dead containers
* Fully support autoconf and suggest
* Add graph_total to the status (thereby making the containers graph
  redundant), CPU and Memory graphs
* Show most graphs as AREASTACK, this allows to get a clearer view of
  both individual and total use
* Use LINESTACK1 to work around munin-contrib/munin#1343
* Include all containers in CPU/Memory/Network config, so data from
  non-running containers is still displayed
* Sprinkle some info and extinfo
* Add ClientWrapper around docker module, providing caching and sorting
* Reverse-engineer author list from git log

9e2b918229 Added env to exclude containers from cpu/memory docker graphs 
It maybe desirable to not generate stats for ephemeral containers.
This commit adds an env variable EXCLUDE_CONTAINER_NAME which is a regex, if it matches
then the container is excluded from the cpu and memory graphs.

fcd2af7b07 Improved docker_ performance when getting CPU/Memory stats 
Added parallel processing using python's muliprocessing module
to fork a new process each for each docker container when gathering
stats.

This vastly improves performance since using a for loop the script
blocks until the stats are returned.
