monitoring-observability

SKILL.md

Comprehensive monitoring setup with metrics collection, log aggregation, alerting, and health checks.

Covers Prometheus for metrics instrumentation, Grafana dashboards for visualization, and structured logging with Winston for log aggregation

Includes pre-built alert rules for high error rates, slow response times, pod failures, and resource saturation

Provides advanced health check endpoints that test database, cache, and external API dependencies with latency tracking

Implements the four golden signals framework: latency percentiles, request volume, error rates, and resource utilization

Monitoring & Observability

When to use this skill

Before Production Deployment: Essential monitoring system setup

Performance Issues: Identify bottlenecks

Incident Response: Quick root cause identification

SLA Compliance: Track availability/response times

Instructions

Step 1: Metrics Collection (Prometheus)

Application Instrumentation (Node.js):

import express from 'express';
import promClient from 'prom-client';
