This repo is a fork of coinbase/watchdog. Please refer to the upstream repo with issues or for new versions.

Coinbase Watchdog

A Datadog codification framework.

The goal of Coinbase Watchdog is to make users lives easier by monitoring Datadog components and ensuring their consistency with data stored in git repository.

Coinbase Watchdog operates in two different ways:

  • Code driven: Users can make a change to component configuration and submit a pull request. Once merged, Coinbase Watchdog will automatically call the Datadog API to update with latest change.
  • UI driven: Coinbase Watchdog will monitor Datadog components for changes. If a change is detected (between actual component and data stored in git) a new pull request will be created. If the pull request was closed, Coinbase Watchdog will restore the component from git, discarding the change.

Quick guide

  • Create config files in watchdog-resources repository under config folder. This folder may contain an arbitrary number of sub folders. This gives users ability to organize the configuration hierarchy for their best needs. Config must be in yaml format and have a .yaml file extension.

Example config file

# cat ./config/infra/sre/components.yaml
meta:
    team: infra/sre

dashboards:
    - 954604

monitors:
    - 6065878

How to setup Coinbase Watchdog from scratch

  • Create a github app, follow the guide on github.com
    • Give permission to read/write to Pull Requests
    • Generate a new RSA private key in github UI.
  • Generate an rsa-ssh key from github app private RSA key: ssh-keygen -y -f <private.key>
    • Add the generated public rsa-ssh key to github repo, where config and data will be stored under Settings -> Deploy Keys. Make sure to check Allow write access. This will grant Coinbase Watchdog permissions to push changes to remote branch and open PRs.
