Docker Monitor

Send Docker statistics to logstash. This can be used in combination with a kibana container to view the metrics reported by the container. Requires running an external elasticsearch container.

Running the container

You can run the container by linking an elasticsearch container

sudo docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 elasticsearch

sudo docker run -d --link elasticsearch:elasticsearch --volume /var/run/docker.sock:/var/run/docker.sock sbrnetmarketing/docker-monitor

Or you can run the container by adding the elasticsearch environment variables

sudo docker run -d --env ELASTICSEARCH_PORT_9200_TCP_ADDR=<es_host> --env ELASTICSEARCH_PORT_9200_TCP_PORT=<es_port> --volume /var/run/docker.sock:/var/run/docker.sock sbrnetmarketing/docker-monitor

If you want to run the container with a different logstash config

sudo docker run -d --link elasticsearch:elasticsearch --volume /var/run/docker.sock:/var/run/docker.sock --volume <logstash_config>:/usr/src/app/docker-monitor.conf sbrnetmarketing/docker-monitor
