# MaintainX Observability ## Overview Implement metrics, structured logging, and alerting for MaintainX integrations to ensure reliability and rapid issue detection. ## Prerequisites - MaintainX integration deployed - Node.js 18+ - Monitoring platform (Prometheus/Grafana, Datadog, or CloudWatch) ## Instructions ### Step 1: Prometheus Metrics ```typescript // src/observability/metrics.ts import { Counter, Histogram, Gauge, Registry } from 'prom-client'; const register = new Registry(); export const metrics = { apiRequests: new Counter({ name: 'maintainx_api_requests_total', help: 'Total MaintainX API requests', labelNames: ['method', 'endpoint', 'status'], registers: [register], }), apiLatency: new Histogram({ name: 'maintainx_api_latency_seconds', help: 'MaintainX API request latency', labelNames: ['method', 'endpoint'], buckets: [0.1, 0.25, 0.5, 1, 2.5, 5, 10], registers: [register], }), rateLimitHits: new Counter({ name: 'maintainx_rate_limit_hits_total', help: 'Times rate limited by MaintainX API', registers: [register], }), workOrdersProcessed: new Counter({ name: 'maintainx_work_orders_processed_total', help: 'Work orders processed', labelNames: ['action', 'status'], registers: [register], }), syncLag: new Gauge({ name: 'maintainx_sync_lag_seconds', help: 'Seconds since last successful sync', registers: [register], }), }; export { register }; ``` ### Step 2: Instr...
