UP — dhanur.me status monitor

Real-time service health dashboard for all dhanur.me services. Written in Go, zero external dependencies, deployed on Render.

Architecture

• Backend: Pure Go standard library (net/http, log/slog, sync). No frameworks.
• Health checks: Concurrent goroutines probe every service every 30 seconds.
• History: 90 data points per service (~45 min rolling window), stored in-memory.
• API: GET /api/status → JSON snapshot; GET /api/health → self-health.
• Frontend: Single embedded HTML file served at /, auto-refreshes every 30 s.

Adding / Editing Services

Create a services.json file next to the binary:

[
  {
    "name":        "my-service",
    "displayName": "My Service",
    "url":         "https://my-service.dhanur.me/api/health",
    "homepageUrl": "https://my-service.dhanur.me",
    "icon":        "fa-solid fa-server",
    "category":    "Core"
  }
]

If services.json is absent the compiled-in defaults are used (authy, tasks, linkr, dhanur.me).

Running locally

go run .
# open http://localhost:8080

Render deployment

The render.yaml in this repo configures a Go web service. Just connect the GitHub repo in the Render dashboard and it deploys automatically on every push to main.

Set up.dhanur.me as the custom domain for the service in Render.
