Go-based uptime monitor for HTTP services with multi-channel alerts on unexpected status codes.

Problem

Services can fail quietly — teams need lightweight checks and alerts when HTTP responses leave the expected range.

Approach

Built a Golang daemon configured via JSON per service: intervals, timeouts, status expectations, and pluggable loggers/notifiers.

Impact

Open-source tool for continuous health checks with per-service logging and alert channels.

About

A Golang health checker that polls configured web services and notifies you when HTTP status codes leave the expected set.

Features

  • Multiple services from JSON configs under services/
  • Loggers per service (and multiple loggers per service)
  • Timeout configuration
  • HTTP status code verification

How to run

Copy service.example.json, configure your endpoints, then run the OS binary. It runs in the background and checks each service on its every interval.
