Graphite & Statsd can be complex to setup. This image will have you running & collecting stats in just a few minutes.

• Proxy Graphite's Django admin behind Nginx

docker run -d\
 --name graphite\
 --restart=always\
 -p 80:80\
 -p 2003-2004:2003-2004\
 -p 2023-2024:2023-2024\
 -p 8125:8125/udp\
 -p 8126:8126\
 hopsoft/graphite-statsd

This starts a Docker container named: graphite

That's it, you're done ... almost.

• Nginx - reverse proxies the graphite dashboard
• Graphite - front-end dashboard
• Carbon - back-end
• Statsd - UDP based back-end proxy

Built using Phusion's base image.

• All Graphite related processes are run as daemons & monitored with runit.
• Includes additional services such as logrotate.

Let's fake some stats with a random counter to prove things are working.

while true; do echo -n "example:$((RANDOM % 100))|c" | nc -w 1 -u localhost 8125; done

Open Graphite in a browser.

• http://localhost/dashboard
• http://localhost/render?from=-10mins&until=now&target=stats.example

Update the default Django admin user account. The default is insecure.

• username: root
• password: root
• email: [email protected]

First login at: http://localhost/account/login Then update the root user's profile at: http://localhost/admin/auth/user/1/

Read up on Graphite's post-install tasks. Focus on the storage-schemas.conf.

1. Stop the container docker stop graphite.
2. Find the configuration files on the host by inspecting the container docker inspect graphite.
3. Update the desired config files.
4. Restart the container docker start graphite.

Note: If you change settings in /opt/graphite/conf/storage-schemas.conf be sure to delete the old whisper files under /opt/graphite/storage/whisper/.

Important: Ensure your Statsd flush interval is at least as long as the highest-resolution retention. For example, if /opt/statsd/config.js looks like this.

flushInterval: 10000

Ensure that storage-schemas.conf retentions are no finer grained than 10 seconds.

[all]
pattern = .*
retentions = 5s:12h # WRONG
retentions = 10s:12h # OK
retentions = 60s:12h # OK

A management interface (default on port 8126) allows you to manage statsd & retrieve stats.

# show all current counters
echo counters | nc localhost 8126

More info & additional commands.

You may find it useful to mount explicit volumes so configs & data can be managed from a known location on the host.

Simply specify the desired volumes when starting the container.

docker run -d\
 --name graphite\
 --restart=always\
 -v /path/to/graphite/configs:/opt/graphite/conf\
 -v /path/to/graphite/data:/opt/graphite/storage\
 -v /path/to/statsd:/opt/statsd\
 hopsoft/graphite-statsd

Note: The container will initialize properly if you mount empty volumes at /opt/graphite, /opt/graphite/conf, /opt/graphite/storage, or /opt/statsd
