Grafana
Grafana Cloud is our observability home for Fly logs, metrics, and dashboards—org-wide signal without self-hosted AWS VMs.
It pairs with Sentry for errors; Grafana shows the longer story across services and tiers.
Where to sign in
| URL | Use it? | |
|---|---|---|
| Grafana Cloud (current) | https://brytebridge.grafana.net/ |
Yes — logs (Loki), metrics (Prometheus), dashboards |
| AWS self-hosted (legacy) | https://brytebridge.grafana.net/ (retired stack) |
No — we operated Grafana, Loki, and Prometheus on AWS instances; that path is being turned off in favor of Grafana Cloud above |
If you still have bookmarks or dashboards from the old AWS-hosted stack, move your day-to-day work to Grafana Cloud at the same workspace URL. New Fly log and metric pipelines land in Cloud, not on the old VMs.
Grafana Cloud is where we watch the health of our running systems—logs, metrics, and dashboards in one managed place instead of babysitting observability servers on AWS.
We are moving observability off self-managed AWS instances and onto Grafana Cloud, which gives us enterprise-grade retention and search without running Loki, Prometheus, and Grafana VMs ourselves.
What lives in Grafana Cloud
Section titled “What lives in Grafana Cloud”Grafana Cloud is not one tool—it is three roles that work together:
| Piece | What it does | Plain English |
|---|---|---|
| Loki | Log storage and search | “What did the app print?” — stdout/stderr from Fly apps, searchable over time |
| Prometheus | Metrics storage | “Is it healthy and how busy is it?” — scrapes from each app’s /metrics and fleet collectors |
| Grafana | Dashboards and exploration | “Show me the story” — charts, panels, and investigations across logs and metrics |
Logs → Loki. Health numbers → Prometheus. Viewing → Grafana.
Moving off AWS for observability
Historically, teams ran log and metrics stacks on AWS instances (agents, forwarders, disks to manage). That work is consolidating into Grafana Cloud:
- Fly org log shippers send every app’s logs to Grafana Cloud—no per-repo log pipeline.
- Org fleet monitor apps scrape
/healthand/metricsand push Prometheus data to Grafana Cloud. - API teams write normal logs and expose standard endpoints; platform owns the pipes into Grafana.
See [Fly.io](/fly/) for what each application must provide (/health, /metrics, stdout logging).
Staging
Staging Fly org → own shipper + scraper → Grafana Cloud (staging data)
UAT
UAT Fly org → own shipper + scraper → Grafana Cloud (UAT data)
Production
Production Fly org → own shipper + scraper → Grafana Cloud (production data)
Tiers stay separated in Fly and in observability—staging logs do not mix with production dashboards by accident.
What API teams do (and do not do)
Section titled “What API teams do (and do not do)”You do:
- Log to stdout / stderr (normal application logging).
- Expose
/healthand/metrics(Prometheus format) on every Fly API. - Use
prom-clientandnstatson Node services (see Fly.io standards).
You do not:
- Stand up your own Loki, Prometheus, or Grafana on AWS for a single API.
- Wire per-app log agents or custom “send logs to S3 then grep” paths for routine deploys.
- Manage Grafana Cloud org credentials in application repos (platform operates the collectors).
Sentry + Grafana (developing)
Section titled “Sentry + Grafana (developing)”We use two complementary layers:
| Layer | Best for |
|---|---|
| Grafana Cloud | Trends, logs, CPU/memory/request rates, fleet health, “what happened around 2:14 PM?” |
| Sentry | User-impacting errors, releases, stack traces, “this deploy broke checkout” |
Cross-linking and alerting between Grafana and Sentry is on the roadmap—e.g. alert when error rates in Sentry correlate with metric spikes in Grafana, or route the right on-call signal to the right channel. Standards for those rules will be documented here as we turn them on.
Until then: Grafana for operations and logs; Sentry for errors and go-live sign-off.
