Introduce logging, monitoring, and alerts with New Relic — host monitoring, NRQL, APM for Node.js, Winston logs, percentiles, and why teams also learn open-source stacks.
Logging, Monitoring & Alerts
Understand logging, monitoring metrics, alerts, dashboards, and status pages — the foundation before any observability tool.
Monitoring Services Overview
Compare paid SaaS tools (CloudWatch, Datadog, New Relic) with self-hosted Prometheus + Grafana + Loki.
New Relic Host Setup
Install the New Relic agent on a machine, explore host entities, and run a CPU stress experiment to see live metrics.
Dashboards, Alerts & NRQL
Build New Relic dashboards, create alert policies with notifications, and query metrics with NRQL.
New Relic APM for Node.js
Instrument an Express app with the New Relic Node agent, generate traffic with loadtest, and explore the APM dashboard.
Application Logs with Winston
Forward Node.js logs to New Relic with Winston and NEW_RELIC_APPLICATION_LOGGING_FORWARDING_ENABLED, then alert on error spikes.
Percentiles, On-Call & Open Source
Why p95/p99 beat averages for latency, a look at infrastructure and status/on-call tools, and the path to Prometheus + Grafana.
