Subscription Editor

A browser-based editor to browse CloudWatch namespaces, select metrics and dimensions, set sensitivity thresholds, generate or schedule reports, and manage maintenance windows. It's secured with Cognito authentication. A single subscription can monitor all matching resources independently.

Capabilities

  • Split-panel layout with keyboard navigation.
  • Preview metric data before subscribing (Shift+click = 24h, Ctrl+click = OpenSearch cross-account).
  • Learned baseline visualization with per-day-of-week sparklines.
  • Version history with JSON diff and one-click rollback.
  • Clone, enable/disable all, and double-click toggle.
  • Deep-link support (?sub=id) for anomaly email links.
  • Session expiry detection with a 60-second keepalive ping.
  • Timezone selector with local time display throughout (detection stays in UTC).
  • Local change management: stage edits and commit with Save, revert with Undo, inspect with Diff.

Wildcard subscriptions

Use regex wildcards in dimension values to monitor every matching resource independently — each gets its own baseline. For example, {"DeliveryStreamName": ".*"} covers all current and future streams with a single subscription.

A dedicated Subscription Editor Guide (PDF) is distributed with the product covering fields, preview, discovery, maintenance, and reports.
