express-status-monitor

Simple, self-hosted module based on Socket.io and Chart.js to report real-time server metrics for Express-based node servers. Monitor can be configured by passing options object into expressMonitor constructor. You can add a series of health checks to the configuration that will appear below the other stats. The health check will be considered successful if the endpoint returns a 200 status code. The HTML page handler is exposed as a pageRoute property on the main middleware function. So the middleware is mounted to intercept all requests while the HTML page handler will be authenticated. If you're using socket.io in your project, this module could break your project because this module by default will spawn its own socket.io instance. To mitigate that, fill websocket parameter with your main socket.io instance as well as port parameter.
