StatsD + Graphite + Grafana 2 + Kamon Dashboards

This image contains a sensible default configuration of StatsD, Graphite and Grafana, and comes bundled with a example dashboard that gives you the basic metrics currently collected by Kamon for both Actors and Traces. There are two ways for using this image:

Using the Docker Index

This image is published under Kamon's repository on the Docker Hub and all you need as a prerequisite is having Docker installed on your machine. The container exposes the following ports:

• 80: the Grafana web interface.
• 81: the Graphite web port
• 8125: the StatsD port.
• 8126: the StatsD administrative port.

To start a container with this image you just need to run the following command:

docker run \
  --detach \
   --publish=80:80 \
   --publish=81:81 \
   --publish=8125:8125/udp \
   --publish=8126:8126 \
   --name kamon-grafana-dashboard \
   kamon/grafana_graphite

If you already have services running on your host that are using any of these ports, you may wish to map the container ports to whatever you want by changing left side number in the --publish parameters. You can omit ports you do not plan to use. Find more details about mapping ports in the Docker documentation on Binding container ports to the host and Legacy container links.

Building the image yourself

The Dockerfile and supporting configuration files are available in our Github repository. This comes specially handy if you want to change any of the StatsD, Graphite or Grafana settings, or simply if you want to know how tha image was built. The repo also has build and start scripts to make your workflow more pleasant.

Using the Dashboards

Once your container is running all you need to do is:

• open your browser pointing to the host/port you just published
• login with the default username (admin) and password (admin)
• configure a new datasource to point at the Graphite metric data (URL - http://localhost:8000) and replace the default Grafana test datasource for your graphs
• then play with the dashboard at your wish...

Making your data last

There are several ways of using Docker volumes to persist the settings and databases of the docker-grafana-graphite container. Here is an example script that will create directories on your host and mount them into the Docker container, allowing graphite and grafana to persist data and settings between runs of the container.

mkdir kamon-grafana-service
cd kamon-grafana-service
mkdir -p data/whisper
mkdir -p data/elasticsearch
mkdir -p data/grafana
mkdir -p log/graphite
mkdir -p log/graphite/webapp
mkdir -p log/elasticsearch
chmod -R 777 *

docker run \
  --detach \
   --publish=80:80 \
   --publish=81:81 \
   --publish=8125:8125/udp \
   --publish=8126:8126 \
   --name kamon-grafana-dashboard \
   --volume=$(pwd)/data/whisper:/opt/graphite/storage/whisper \
   --volume=$(pwd)/data/elasticsearch:/var/lib/elasticsearch \
   --volume=$(pwd)/data/grafana:/opt/grafana/data \
   --volume=$(pwd)/log/graphite:/opt/graphite/storage/log \
   --volume=$(pwd)/log/elasticsearch:/var/log/elasticsearch \
   kamon/grafana_graphite

Now go explore!

We hope that you have a lot of fun with this image and that it serves it's purpose of making your life easier. This should give you an idea of how the dashboard looks like when receiving data from one of our toy applications:
