rollops-plugin-datadog

A Rollops metric-provider plugin backed by Datadog. It resolves a Datadog metrics query to a single scalar so rollout analysis can gate a canary on Datadog metrics, the way it does on Prometheus.

How it works

Rollops calls the plugin's query_metric tool with a Datadog metrics query. The plugin queries Datadog's /api/v1/query endpoint over a lookback window (default 5m) and returns the most recent point of the first series. Wire those values into a CEL condition in the analysis block:

analysis:
  provider: datadog
  plugin: ~/.rollops/plugins/datadog
  sha256: <pin>
  metrics:
    - name: errorRate
      query: "avg:trace.http.request.errors{service:checkout}.as_rate()"
    - name: p99
      query: "p99:trace.http.request.duration{service:checkout}"
  condition: "errorRate < 0.05 && p99 < 0.8"
  count: 3
  interval: 30s

Configuration

Credentials come from the plugin's own environment, never from the Rollops target spec (which carries only the query string):

Env var	Required	Default	Description
DD_API_URL	no	https://api.datadoghq.com	Use the EU site if applicable
DD_API_KEY	yes	—	Datadog API key
DD_APP_KEY	yes	—	Datadog application key
DD_WINDOW	no	5m	Lookback window (Go duration)
