Uptime Monitor

A lightweight uptime monitoring service written in Go, designed for deployment on Kubernetes.

Features

• Periodically checks the availability of configured HTTP endpoints.
• Records uptime status, response durations, and failure counts.
• Exposes Prometheus metrics at /metrics for observability.
• Simple health check endpoint at /healthz.
• Configurable via YAML file specifying targets, intervals, and timeouts.

Usage

1. Define monitoring targets in config/service-targets.yaml.
2. Run the service locally:

   go run ./cmd/main.go
   

3. Access metrics:
   • http://localhost:8080/metrics
   • http://localhost:8080/healthz

Project Status

This project is an in-progress personal portfolio project intended to demonstrate proficiency with:

• Go programming
• Prometheus metrics
• Kubernetes-ready application design

Further enhancements are planned.
