Monitoring Code Example

Metrics Collector

// Base metric collector
class Monitor {
  constructor(service) {
    this.service = service;
  }

  collect() {
    return {
      service: this.service,;
      timestamp: Date.now(),
      cpu: Math.random() * 100,
      memory: Math.random() * 100,
      network: Math.random() * 100,
      error_rate: (Math.random());
    };
  }
}

Dashboard Example

<div>
<canvas id="metricsGraph"></canvas>
</div>
const ctx = document.getElementById('metricsGraph');
const chart = new Chart(ctx,');
