Health Endpoints

Strait exposes two health endpoints for infrastructure orchestration:

Liveness: `GET /health`

Returns 200 if the process is alive. Use as Kubernetes liveness probe.

Readiness: `GET /health/ready`

Returns 200 when all dependencies are ready. Returns 503 with details when not ready.

{
  "ready": false,
  "checks": {
    "database": "ok",
    "redis": "unavailable"
  }
}

The health check system uses a component registry (apps/strait/internal/health/registry.go) where subsystems register their health check functions.

Kubernetes Configuration

livenessProbe:
  httpGet:
    path: /health
    port: 8080
  initialDelaySeconds: 5
  periodSeconds: 10

readinessProbe:
  httpGet:
    path: /health/ready
    port: 8080
  initialDelaySeconds: 10
  periodSeconds: 5
  failureThreshold: 6

Prometheus Metrics

Metrics exposed at GET /metrics:

Metric	Type	Description
`strait_run_transitions_total`	Counter	FSM state transitions (by from_status, to_status)
`strait_dispatch_duration_seconds`	Histogram	HTTP dispatch latency (by job_id, outcome)
`strait_dequeue_duration_seconds`	Histogram	Queue polling latency
`strait_worker_pool_active`	Gauge	Active worker goroutines
`strait_worker_pool_queued`	Gauge	Tasks waiting in pool buffer
`strait_analytics_query_duration_seconds`	Histogram	Analytics query latency (by period_hours)
`strait_bulk_operations_total`	Counter	Bulk trigger/cancel operations
`strait_bulk_items_processed_total`	Counter	Items processed in bulk operations
`strait_bulk_child_cancellations_total`	Counter	Cascading child run cancellations
`strait_webhook_retry_attempts_total`	Counter	Webhook delivery retry attempts

Monitoring Assets

Use the monitoring assets in packages/monitoring/ as a baseline:

grafana-authz-rbac-dashboard.json
alerts-authz-rbac.yaml

Core Signals

HTTP authz failures (401, 403)
Permission cache hits/misses/evictions
RBAC control-plane mutation rate
Audit event insert errors
Webhook delivery failures
Worker pool utilization
Database connection pool saturation
Analytics query latency spikes
Bulk operation failure rate

Recommended SLO Checks

403 rate remains near baseline after RBAC or policy changes
Permission cache hit ratio >= 0.80 under normal load
Audit event write error rate = 0
Webhook terminal failure rate stays within agreed threshold
Health endpoint responds within 1s
Worker pool active/capacity ratio < 0.9
Analytics query p95 < 2s
Bulk cancel success rate >= 99%
