Telemetry Aggregator

Telemetry Aggregator

When you activate

• Powers dashboard/ rendering
• Powers /portfolio-pulse skill
• User asks: "give me numbers across all products", "what's the total MRR?", "total errors today?"

What you produce

A normalized telemetry payload — usable by the dashboard's renderer or any downstream agent:

{
  "as_of": "2026-05-19T14:32:00Z",
  "totals": {
    "mrr_usd": 0,
    "paying_customers": 0,
    "active_users_7d": 0,
    "errors_24h": 0,
    "search_impressions_7d": 0
  },
  "products": [
    {
      "slug": "linkedup",
      "stage": "mvp",
      "metrics": {
        "mrr_usd": 0,
        "paying_customers": 0,
        "active_users_7d": 0,
        "signups_7d": 0,
        "errors_24h": 0,
        "top_queries_7d": [{"query": "...", "clicks": 0, "impressions": 0, "position": 0}],
        "health_score": 0.0
      },
      "connectors_status": {
        "stripe": "connected | not_connected | error",
        "posthog": "connected | not_connected | error",
        "sentry": "connected | not_connected | error",
        "gsc": "connected | not_connected | error"
      }
    }
  ]
}

Protocol

1. Read all products/*/product.config.json.
2. For each product, for each connector listed, call the connector with the credentials referenced.
3. Handle errors gracefully — a missing connector returns not_connected, an erroring one returns error with a brief reason in the dashboard, not a crash.
4. Compute the composite health_score per product:

   health = w_retention * D7_retention + w_revenue * MRR_growth + w_errors * (1 - error_rate_normalized)
   

   weights default: 0.4 / 0.3 / 0.3. Tune per product type.
5. Cache results for 5 minutes (don't hammer the APIs).

Connectors

All in dashboard/lib/connectors/:

• stripe.ts — fetchStripeMetrics(account_id)
• posthog.ts — fetchPostHogMetrics(project_id)
• sentry.ts — fetchSentryMetrics(org, project)
• gsc.ts — fetchGSCMetrics(property)
• plausible.ts — fetchPlausibleMetrics(domain)
• ga4.ts — fetchGA4Metrics(measurement_id)

Each returns a normalized shape: { status: 'ok' | 'error', data?: {...}, error?: string }.

Sources

• stack/analytics-stack.md (for the connector list)
• dashboard/lib/connectors/*.ts (the actual implementations)

What you don't do

• Don't fail the whole aggregation because one connector errors. Return partial data.
• Don't store secrets in product.config.json — only references.
• Don't call connectors more often than every 5 minutes per product.
