Grafana reporting

The following command allow you to run a fresh grafana server :

docker run -i -p 3000:3000 grafana/grafana

Once running, you need to set up an ElasticSearch data-source :

• select proxy mode
• Select version 2.x of ElasticSearch
• make the URL point your ES node
• Specify the index name. By default, it should be :

[james-metrics-]YYYY-MM

Import the different dashboards in this directory.

You then need to enable reporting through ElasticSearch. Modify your James ElasticSearch configuration file accordingly. To help you doing this, you can take a look to GitHub. Note that you need to run a guice/cassandra version of James.
