artillery-plugin-datadog

NPM Version Build Status Downloads Stats

Artillery plugin that reports load test results to Datadog.

The plugin uses datadog-metrics to submit Artillery metrics to Datadog over HTTPS and does not require a StatsD server (Datadog Agent). An alternative to this is artillery-plugin-statsd which uses StatsD.

Usage

  • Install this plugin and Artillery (npm install artillery artillery-plugin-datadog)
  • Create a configuration file for Artillery. Specify Datadog as the plugin to use.
# skynet.yaml
config:
  target: https://skynet.org
  phases:
    - duration: 3
      arrivalRate: 15
      name: "First stage"
  plugins:
    datadog:
      # Custom hostname (leave blank if not desired)
      host: ''
      # Custom metric prefix (defaults to 'artillery.')
      prefix: 'artillery.'
      # Additional tags for all metrics
      tags:
        - 'mode:test'
scenarios:
  - flow:
      - get:
          url: /status

Run artillery and specify Datadog API key as an environment variable.

$ DATADOG_API_KEY=xxxxxxxxxxxx artillery run skynet.yaml

  • artillery.scenarioDuration.max: Max scenario duration
  • artillery.scenarioDuration.median: Median scenario duration
  • artillery.scenarioDuration.p95: 95th percentile scenario duration
