Resource usage collected from `docker stats` API\nand sent to graphite installation.\n\nThis plugin treats containers as tasks that run as parts of apps.\nTo set an application name, you should set label `collectd_docker_app`\nor env variable `COLLECTD_DOCKER_APP` to the application name.\n\nYou can also set the application name by setting `COLLECTD_DOCKER_APP_ENV`\nto point to the environment variable to use for the app name.\nFor example, marathon sets `MARATHON_APP_ID` and by setting\n`COLLECTD_DOCKER_APP_ENV` to `MARATHON_APP_ID` you would get the\nmarathon app id. In this case it is also useful\nto set `COLLECTD_DOCKER_APP_ENV_TRIM_PREFIX` to trim prefix since\nstring `.` is limited by 63 characters.\n\nTo set a task name,you should set label `collectd_docker_task`\nor env variable `COLLECTD_DOCKER_TASK` to the task name. Task name\nis optional and only useful when you can run several instances of\nthe same application on the same host. With task name you could\nsee metrics of individual containers.\n\nAlternatively, you could tell this plugin where task id is located\nby setting `collectd_docker_task_label` label pointing to\nthe other label name or `COLLECTD_DOCKER_TASK_ENV` env var pointing to\nthe other env variable. For example, mesos sets `MESOS_TASK_ID`\nand by setting `COLLECTD_DOCKER_TASK_ENV` to `MESOS_TASK_ID` you\nwould get task id from mesos. In this case it is also useful\nto set `COLLECTD_DOCKER_TASK_ENV_TRIM_PREFIX` to trim prefix since\nstring `.` is limited by 63 characters.\n\nContainers can be added and removed on the fly, no need to restart collectd.\n\n## Reported metrics\n\nMetric names look line this:\n\n```\ncollectd..docker_stats....\n```\n\nGauges:\n\n* CPU\n * `cpu.user`\n * `cpu.system`\n * `cpu.total`\n\n* Memory overview\n * `memory.limit`\n * `memory.max`\n * `memory.usage`\n\n* Memory breakdown\n * `memory.active_anon`\n * `memory.active_file`\n * `memory.cache`\n * `memory.inactive_anon`\n * `memory.inactive_file`\n * `memory.mapped_file`\n * `memory.pg_fault`\n * `memory.pg_in`\n * `memory.pg_out`\n * `memory.rss`\n * `memory.rss_huge`\n * `memory.unevictable`\n * `memory.writeback`\n\n* Network (bridge mode only)\n * `net.rx_bytes`\n * `net.rx_dropped`\n * `net.rx_errors`\n * `net.rx_packets`\n * `net.tx_bytes`\n * `net.tx_dropped`\n * `net.tx_errors`\n * `net.tx_packets`\n\n## Grafana dashboard\n\nGrafana 2 [dashboard](grafana2.json) is included.\n\n![screenshot](https://github.com/bobrik/collectd-docker/raw/master/screenshot.png)\n\n#### Graphite metrics extracted from the dashboard\n\n* CPU usage per second\n\n```\naliasByNode(scaleToSeconds(nonNegativeDerivative(collectd.$host.docker_stats.$app.$task.gauge.cpu.total), 1), 3, 4, 1)\n```\n\n* Memory limit\n\n```\nalias(averageSeries(collectd.$host.docker_stats.$app.$task.gauge.memory.limit), 'limit')\n```\n\n* Memory usage\n\n```\naliasByNode(collectd.$host.docker_stats.$app.$task.gauge.memory.usage, 3, 4, 1)\n```\n\n* Network bytes per second tx\n\n```\naliasByNode(scaleToSeconds(nonNegativeDerivative(collectd.$host.docker_stats.$app.$task.gauge.net.tx_bytes), 1), 3, 4, 1, 7)\n```\n\n* Network bytes per second rx\n\n```\naliasByNode(scaleToSeconds(nonNegativeDerivative(collectd.$host.docker_stats.$app.$task.gauge.net.rx_bytes), 1), 3, 4, 1, 7)\n```\n\n* Network packets per second tx\n\n```\naliasByNode(scaleToSeconds(nonNegativeDerivative(collectd.$host.docker_stats.$app.$task.gauge.net.tx_packets), 1), 3, 4, 1, 7)\n```\n\n* Network packets per second rx\n\n```\naliasByNode(scaleToSeconds(nonNegativeDerivative(collectd.$host.docker_stats.$app.$task.gauge.net.rx_packets), 1), 3, 4, 1, 7)\n```\n\n## Running\n\nMinimal command:\n\n```\ndocker run -d -v /var/run/docker.sock:/var/run/docker.sock \\\n -e GRAPHITE_HOST= -e COLLECTD_HOST= \\\n bobrik/collectd-docker\n```\n\n### Environment variables\n\n* `COLLECTD_HOST` - host to use in metric name, defaults to `MESOS_HOST` if defined.\n* `COLLECTD_INTERVAL` - metric update interval in seconds, defaults to `10`.\n* `GRAPHITE_HOST` - host where carbon is listening for data.\n* `GRAPHITE_PORT` - port where carbon is listening for data, `2003` by default.\n* `GRAPHITE_PREFIX` - prefix for metrics in graphite, `collectd.` by default.\n\nNote that this docker image is very minimal and libc inside does not\nsupport `search` directive in `/etc/resolv.conf`. You have to supply\nfull hostname in `GRAPHITE_HOST` that can be resolved with nameserver.\n\n## License\n\nMIT\n","has_starred","hub_user","immutable_tags_settings",{"_71":11,"_72":73},"enabled","rules",[74],".*","is_automated","permissions",{"_78":17,"_79":11,"_80":11},"read","write","admin","user","storage_size",90640367,"orgData","recentTags",[87],{"_88":40,"_89":90,"_91":92,"_93":94,"_95":96,"_46":114,"_115":90,"_116":29,"_117":52,"_53":118,"_119":120,"_121":105,"_122":114,"_123":62,"_124":17},"content_type","creator",42865,"full_size",90634205,"id",2559110,"images",[97],{"_98":99,"_100":101,"_102":103,"_104":105,"_106":107,"_108":103,"_109":103,"_110":-5,"_111":112,"_59":62,"_113":-5},"architecture","amd64","digest","sha256:b77c3407692c3894ecfa81ac8d89658326d48018d859b01fbda653da33a0bff2","features","","last_pulled","2026-09-20T03:39:57.844215081Z","last_pushed","2016-04-06T15:01:51Z","os","os_features","os_version","size",90634237,"variant","2016-04-06T15:01:50.741016Z","last_updater","last_updater_username","media_type","latest","repository",621807,"tag_last_pulled","tag_last_pushed","tag_status","v2","sbxKitMetadata","isPotentialSpam","isHubSbxKitsEnabled","displaySecurityMetadata","tagAttestations","tagsHaveAttestations",[],"routes/_layout.r.$namespace.$reponame.tags",{"_34":134,"_141":142,"_130":151,"_152":11},{"_36":135,"_38":136,"_41":42,"_43":44,"_45":11,"_46":47,"_48":49,"_50":137,"_53":31,"_28":29,"_54":55,"_56":-5,"_57":58,"_59":60,"_61":62,"_63":-5,"_64":58,"_65":66,"_67":11,"_68":29,"_69":138,"_75":17,"_76":140,"_81":29,"_82":83},[],[40],[52],{"_71":11,"_72":139},[74],{"_78":17,"_79":11,"_80":11},"tags",{"_143":60,"_144":-5,"_145":-5,"_146":147},"count","next","previous","results",[148],{"_88":40,"_89":90,"_91":92,"_93":94,"_95":149,"_46":114,"_115":90,"_116":29,"_117":52,"_53":118,"_119":120,"_121":105,"_122":114,"_123":62,"_124":17},[150],{"_98":99,"_100":101,"_102":103,"_104":105,"_106":107,"_108":103,"_109":103,"_110":-5,"_111":112,"_59":62,"_113":-5},[],"canDeleteTags","actionData","errors"]
