Docker Image for Graphite & Statsd

Get Graphite & Statsd running instantly

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

Quick Start

docker run -d\
 --name graphite\
 --restart=always\
 -p 80:80\
 -p 81:81\
 -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.

Includes the following components

• Nginx - reverse proxies the graphite dashboard
• Graphite - front-end dashboard
• Carbon - back-end
• Statsd - UDP based back-end proxy
• Grafana - front-end dashboard (more refined than Graphite)

Mapped Ports

By default, statsd listens on the UDP port 8125. If you want it to listen on the TCP port 8125 instead, you can set the environment variable STATSD_INTERFACE to tcp when running the container.

Mounted Volumes

Base Image

Built using Phusion's base image.

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

Start Using Graphite & Statsd

Send Some Stats

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 127.0.0.1 8125; done

Visualize the Data

Open Graphite in a browser.

• http://localhost:81/dashboard
• http://localhost:81/render?from=-10mins&until=now&target=stats.example

Secure the Django Admin

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

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

First login at: http://localhost:81/account/login Then update the root user's profile at: http://localhost:81/admin/auth/user/1/

Change the Configuration

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

Statsd Admin Management Interface

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.

Secure Grafana

Update the default Grafana admin account. The default is insecure.

• username: admin
• password: admin
• email: admin@localhost

First login at: http://localhost Then update the admin user's profile at: http://localhost/admin/users/edit/1

Connect Grafana to Graphite

Visit http://localhost/datasources/new Then configure the Graphite data source with the URL http://localhost:81

A Note on Volumes

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

Memcached config

If you want Graphite to use an existing Memcached server, set the following environment variables:

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\
 -e "MEMCACHE_HOST=127.0.0.1:11211"\  # Memcached host(s) comma delimited
 -e "CACHE_DURATION=60"\              # in seconds
