Chihuahua

chihuahua

Chihuahua は Datadog monitors を管理するツールです.

Caution

  • Datadog monitors を YAML DSL で管理してみる試みです
  • Monitor Name や Monitor Tags で絞り込んで任意の Monitor のみ抽出して管理出来る筈です
  • 基本的には codenize-tools/barkdog を使いましょう

Installation

Add this line to your application's Gemfile:

gem 'chihuahua'

And then execute:

$ bundle

Or install it yourself as:

$ gem install chihuahua

Usage

export DATADOG_API_KEY=...
export DATADOG_APP_KEY=...

bundle exec chihuahua init
bundle exec chihuahua export --project=your_project_name --tags=project:foo,stage:production --dry-run
bundle exec chihuahua export --project=your_project_name --tags=project:foo,stage:production
vi ./monitors/your_project_name/monitors.yml
bundle exec chihuahua apply --project=your_project_name --dry-run
bundle exec chihuahua apply --project=your_project_name

Help

$ bundle exec chihuahua --help
Commands:
  chihuahua apply           # Monitor 設定を apply する
  chihuahua export          # Monitor 設定を export する
  chihuahua help [COMMAND]  # Describe available commands or one specific command
  chihuahua init            # Project の Root ディレクトリ(./monitors)を作成する.
