docker-junos-datadog

Docker container to convert Juniper Telemetry streaming data into Datadog The contaimer is designed to work in pair with the datadog container⁠

How does it works

Juniper devices are able to stream statistics periodically to a collector. Various format are supported : UDP/TCP, JSON or GPB

This project support

• JSON over UDP send by QFX5100 (analyticsd)

2 Containers per device are needed to convert the Juniper format and send it to datadog

• Juniper container running Fluentd that will accept Juniper Format and convert it into Statsd
• Datadog container running the datadog agent that accept Statsd as input, this container is provided by datadog⁠

This repo explain how to :

• Configure QFX5100 to stream data
• Create the Juniper container
• Configure the datadog container

Deployment Guideline

Each Juniper device require 2 containers to send data to datadog.
Because container are lightweight and flexible there are multiple possible deployment scenario :

• Containers running on each Juniper device inside a Guest VM that support Docker⁠,
• Containers for all devices deployed on a central server, each device will send data to a different port.

Juniper Container

The Juniper container is running Fluentd with 2 specifics plugins

• Input plugin that accept JSON over UDP send by QFX5100 available here⁠
• Output Plugin to send Statsd format inspired from https://github.com/fakechris/fluent-plugin-statsd⁠

Both containers are available on Docker cloud :

• datadog/docker-dd-agent
• juniper/junos-dogstatsd

Installation Guide

How to configure Juniper devices

A configuration example is provided for QFX5100 inside juniper_templates directory⁠

Start the Datadog Container

docker run -d --name dd_qfx5100 -e API_KEY={your_api_key_here} -h "{device_hostname}"  datadog/docker-dd-agent dogstatsd

Start the Juniper Container

docker run --link dd_qfx5100:dogstatsd -p 51020:51020/udp -d juniper/junos-dogstatsd /sbin/my_init

TODO

• Add instruction to have multiple QFX supported on the same server
• Add ansible playbook to automate deployment
