  "account": "When assessing the best backend for custom notification metrics, begin by defining three event types: accepted, attempted, and terminal. Accepted signifies the application taking ownership, attempted represents a provider call, and terminal denotes delivered, permanently failed, or exhausted based on the service's policy. Retries increment the attempt count but never mark work as accepted.\n\nTo ensure cost attribution, avoid labels that provide answers to future questions. Instead, use coarse cost_bucket labels, such as a contracted support tier or internal business unit, and keep the mapping from customer to bucket in the source system. This approach reduces retention complexity and mitigates the risk of identifying individuals.\n\nConsider dimensions like channel, queue, message class, tenant cost bucket, provider class, region, and outcome when building your dashboard. Personal data, such as customer email addresses and ticket IDs, should reside in controlled logs or traces, not metric labels.\n\nWhen comparing cloud and self-hosted APIs, conduct a procurement test using identical synthetic workloads with no personal data. Record evidence regarding cardinality, query behavior, operational burden, and cost. Test both steady and retry-storm workloads to evaluate the systems' handling of retries and potential failures.\n\nChoose a backend that aligns with your team's capabilities and the operational requirements of your notification service. No single backend can eliminate all trade-offs, but careful consideration of the outlined factors will guide you toward the most suitable solution for your specific needs.",
  "summary": "A notification metric is cheap only when it can answer who created the work, which delivery stage failed, and who owns the retry. Choose the backend after fixing that attribution model. For a customer-support notification service, I would compare four paths with the same bounded dataset: CloudWatch, Grafana Cloud's free offering, PostHog, and a small self-hosted metrics API. The winner is the…",
