Monitoring, And Visualizing your Node.JS server with Open Source tools
summary
Tracks concrete Node.js metrics — process memory usage, average response time, CPU and error counts — and sends them into InfluxDB via the open source telegraf plugin and the JavaScript client. Uses the prebuilt Node.js Monitoring Template, demonstrates writing points with timestamps, warns to create read/write tokens and call client.close, and notes there are ~400 telegraf plugins. Shows visualization options (Influx dashboards, Grafana, Plotly) and lightweight tools for ad hoc analysis like ClinicJS and express-status-monitor.
