kaihen 07e747a1e8 Fix for docker_containers 2021-07-22 13:58:03 +02:00
Lars Kruse c633ff00ea docker_: ignore contains which are not running 
Some containers may be in "restarting" state.  We should ignore these.

Thanks, ogmueller!

Closes: #1209

Daniel Neugebauer 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)

Lars Kruse 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).

Olivier Mehani 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

Rowan Wookey 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.

Rowan Wookey 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.
