Prometheus OTel Go Example

Overview

This repository provides a Go application instrumented with OpenTelemetry for collecting and exporting metrics to Prometheus. The metrics can then be visualized using any Prometheus-compatible monitoring tool, such as Grafana.

Prerequisites

Go installed (version 1.22 or later)
Docker and Docker Compose installed

Setup

Clone the repository:

git clone https://github.com/Rishabh3321/otel-prom-go-example.git

Start the application and Prometheus:

cd otel-go-example
docker-compose up -d

Accessing Metrics

Prometheus:

Open your web browser and navigate to http://localhost:9090.
Use the query language to explore and visualize the collected metrics.

Customization

Metrics: Modify the main.go file to add or remove metrics as needed.
Exporters: Adjust the OpenTelemetry configuration in the Dockerfile to use different exporters (e.g., Jaeger, Zipkin).
Prometheus Configuration: Customize the prometheus.yml file to configure Prometheus' behavior.
