Monitoring Your App with Performance Monitor

You can't improve what you can't measure. Performance Monitor gives you the instrumentation to understand where your application spends time.

Install the SDK

npm install @nexatech/monitor
# or
pip install nexatech-monitor

Initialize

import { Monitor } from '@nexatech/monitor';

Monitor.init({
  dsn: process.env.NEXATECH_MONITOR_DSN,
  tracing: true,
  sampleRate: 0.1, // trace 10% of requests
});

Custom spans

const span = Monitor.startSpan('db.query', { table: 'users' });
const result = await db.query('SELECT ...');
span.finish();

Alerts

Set a p95 latency alert in 30 seconds through the dashboard: Navigate to Alerts → New Alert → Latency p95 → threshold 500ms → Slack notification.
