Integration Guide

Adding Metrics to Server

To integrate the monitoring system into the MCP server:

// In src/server.ts or src/index.ts
 
import { TelemetryCollector } from './monitoring/index.js';
import { DGXMetrics } from './monitoring/index.js';
 
// Initialize telemetry
const telemetry = new TelemetryCollector(logger);
const metrics = new DGXMetrics();
 
// Record requests
const timer = telemetry.startRequest('list_resources');
try {
  // ... handle request ...
  timer(); // Records success
} catch (error) {
  telemetry.recordRequest('list_resources', timer.elapsed(), 'error');
}
 
// Record tool execution
const toolStart = Date.now();
try {
  const result = await executeTool(name, args);
  telemetry.recordToolExecution(name, Date.now() - toolStart, 'success');
} catch (error) {
  telemetry.recordToolExecution(name, Date.now() - toolStart, 'error');
}
 
// Export metrics endpoint (if using HTTP)
app.get('/metrics', (req, res) => {
  res.set('Content-Type', 'text/plain');
  res.send(metrics.export());
});

GPU Metrics Collection

// In hardware detection code
import { DGXMetrics } from './monitoring/index.js';
 
const metrics = new DGXMetrics();
 
// After detecting GPU stats
for (const gpu of gpuList) {
  metrics.setGPUMetrics(gpu.index, {
    temperature: gpu.temperature,
    utilization: gpu.utilizationGpu,
    memoryUsed: gpu.memoryUsed,
    memoryTotal: gpu.memoryTotal,
    powerUsage: gpu.powerDraw,
  });
}
