How Does Prometheus Work?

woman focused on Prometheus Integration

The Prometheus server gathers metrics from various sources, including your servers and other monitoring targets, by periodically fetching data from their metric endpoints using HTTP requests, following a predefined schedule. When dealing with transient or short-lived jobs that can't be regularly polled for metrics, Prometheus offers a Push gateway solution. 

This intermediary server allows monitoring targets to send their metrics before they terminate. For our case, we stick to the implementation using the Prometheus pull method.

Prometheus also offers powerful querying capabilities through PromQL (Prometheus Query Language). This functional query language enables the real-time selection and aggregation of time series data.

NextJS Prometheus Integration For Enhanced Performance Monitoring

woman learning about Prometheus Integration

The Nextjs Prometheus package offers a streamlined way to integrate Prometheus with Next.js applications to enhance overall observability. This package essentially modifies Next.js modules responsible for server-side rendering (SSR) operations, such as:

  • getServerSideProps
  • Middleware
  • API routes

Key Features of Nextjs Prometheus

Monkey-Patching

This clever technique tweaks Next.js internals without disturbing the original framework, effectively providing insights into application performance.

SSR Metrics

It effectively tracks metrics associated with server-side rendering, particularly crucial for applications leaning heavily on SSR for performance and SEO.

Compatibility

The Nextjs Prometheus package requires Next.js version 12.0.9 or later, with specific guidelines for middleware utilization.

Setting Up Prometheus with Next.js

Install the Package

To kickstart the integration, add Nextjs Prometheus to your project:

bash
npm install Nextjs Prometheus

Modify package.json

Update your start script to include Prometheus instrumentation:

json
"start": "NODE_OPTIONS='--require nextjs-prometheus' next start"

Wrap Your SSR Functions

Utilize a higher-order function (HOF) to wrap your getServerSideProps functions for tracking metrics. Here’s an example:

javascript
// withPrometheusMetrics.js
function withPrometheusMetrics(getServerSidePropsFunction) {
    return async function (context) {
        const start = process.hrtime();
        const result = await getServerSidePropsFunction(context);
        const diff = process.hrtime(start);
        const duration = diff[0] * 1e3 + diff[1] / 1e6; // Convert to milliseconds
        getServerSidePropsCounter.inc();
        getServerSidePropsHistogram.observe(duration);
        return result;
    };
}

Implement in Your Pages

javascript
// pages/yourPage.js
import withPrometheusMetrics from '../withPrometheusMetrics';

export async function getServerSideProps(context) {
    // Your original logic
}

export default withPrometheusMetrics(getServerSideProps);

Alternative Approaches to Prometheus NextJS Integration

If you opt not to use monkey-patching, another way to integrate Prometheus is by utilizing the prom-client library directly. This approach involves creating an API route to expose metrics, providing you with an additional level of flexibility in handling performance data.

Create an API Route

javascript
// pages/api/metrics.js
import { register, collectDefaultMetrics } from 'prom-client';

collectDefaultMetrics();

export default async function handler(req, res) {
    res.setHeader('Content-Type', register.contentType);
    res.end(await register.metrics());
}

Configure Prometheus

Ensure your Prometheus server scrapes metrics from your Next.js app by configuring prometheus.yml accordingly:

text
scrape_configs:
  - job_name: 'nextjs-app'
    metrics_path: '/api/metrics'
    static_configs:
      - targets: ['localhost:3000']

Integrating Prometheus with Next.js is a powerful strategy for thoroughly monitoring your application. Whether you choose the Nextjs Prometheus package for effortless SSR instrumentation or prefer to implement customized metrics collection using prom-client, both methods offer valuable insights into your application's performance and behavior.
