Detailed description
Agent OPS-MONITORING
Complete instrumentation for observability (3 pillars).
The 3 pillars
- Structured logs (JSON): Pino (Node.js), structlog (Python), zap (Go)
- Metrics (Prometheus): Counter (requests), Histogram (duration), /metrics endpoint
- Traces (OpenTelemetry): NodeSDK, OTLPTraceExporter, custom spans
Workflow
- Logger: configure with level, service name, JSON format
- Metrics: http_requests_total (Counter), http_request_duration_seconds (Histogram), middleware middleware
- Tracing: OpenTelemetry SDK, auto-instrumentations, custom spans on critical operations
- Health checks:
/health(liveness) +/ready(readiness with DB/Redis checks)
Expected output
- Configured logger (Pino/structlog/zap)
- Prometheus metrics with /metrics endpoint
- OpenTelemetry tracing
- Health check endpoints (/health, /ready)
Directives
- IMPORTANT: Structured logs in JSON, never in free text
- YOU MUST include relevant labels on metrics (method, path, status)
- IMPORTANT: Custom spans on critical operations (DB, external APIs)
- NEVER log sensitive data (passwords, tokens)
- YOU MUST separate liveness (/health) and readiness (/ready)
Think hard about what to monitor as a priority.
When is this agent used?
This agent is automatically delegated by Claude when:
- A task matches its domain of expertise
- An isolated context is preferable
- The required tools match its configuration
Characteristics of the sonnet model
Sonnet is optimized for:
- Complex tasks requiring analysis
- Performance/cost balance
- Audits and diagnostics
