Each service is an independent unit of work. Pyroscope applies to all 8 services. Faro applies to the 5 services with browser-facing frontends.

Each service has separate issues for code changes and Helm chart changes.

Total estimated effort: ~27h (includes infrastructure validation) Prerequisite: Phase 2 complete; Pyroscope and Alloy faro.receiver deployed to dev

Issue: Deploy Grafana Pyroscope

Labels: phase-3 infrastructure profiling Estimated Effort: ~1.5 days

Issue: Phase 3 Infrastructure Validation (dev only)

Estimated Effort: ~½ day

Description

Validate that Pyroscope and Alloy's Faro receiver are correctly deployed and accepting data in ca7f8f-dev before beginning per-service Phase 3 onboarding. This is the go/no-go gate for Phase 3 service work.

Unlike Phase 1, there is no synthetic profiling data generator equivalent to telemetrygen. Pyroscope is validated via health check and API reachability. The Faro receiver is validated by sending a test payload directly to Alloy — no browser or instrumented service required. Per-service data flow validation is covered by each service's acceptance criteria.

Requirements

  • Confirm Pyroscope is running and healthy in ca7f8f-dev (query the /ready endpoint)
  • Confirm Pyroscope is reachable from within the namespace (e.g. from a debug pod)
  • Send a minimal test payload to Alloy's Faro receiver endpoint (http://alloy:12347/collect) and confirm it is accepted (HTTP 200)
  • Confirm the test Faro payload appears as a log entry in Loki (dev)
  • Resolve any RBAC, network policy, or Alloy pipeline issues before proceeding

Expected Outcome

Pyroscope is running and reachable from within ca7f8f-dev. Alloy's Faro receiver is accepting payloads and routing them to Loki. The infrastructure is confirmed ready for per-service Phase 3 onboarding.

Acceptance Criteria

  • Pyroscope /ready endpoint returns healthy in ca7f8f-dev
  • Pyroscope reachable from within the namespace on its configured port
  • Alloy faro.receiver accepts a test POST to /collect without error
  • Test Faro payload visible as a log entry in Grafana → Loki (dev)
  • Any network policy or RBAC issues identified and resolved
