inutano/dmc-setup repository overview

⁠Docker metrics collector

⁠Prerequisites

• docker-compose (version 3)

⁠How it works

docker-compose up runs four containers named elk, dmc-setup, telegraf, and fluentd. dmc-setup creates index mapping on specified Elasticsearch endpoint. telegraf watches containers running on the same host except for elk, fluentd, and itself, then output ./log/telegraf/metrics.json. fluentd send metrics.json to Elasticsearch server using tail -f method. Collected metrics data can be visualized via http://localhost:5601 by Kibana.

⁠Get Started

⁠Launch Elasticserach/Telegraf/Fluentd on the same host

$ git clone https://github.com/inutano/docker-metrics-collector
$ cd docker-metrics-collector
$ docker-compose up &

and you're ready to collect resource usage from docker container execution!

⁠Send metrics data to an external Elasticsearch server

Use shell environment variable to set hostname and port of Elasticsearch.

$ git clone https://github.com/inutano/docker-metrics-collector
$ cd docker-metrics-collector
$ export ES_HOST=<your Elasticsearch endpoint>
$ export ES_PORT=<your Elasticsearch port number>
$ docker-compose up telegraf &
