About this Mod

A mod that lets you know when your sites are down during the game.

How does it work?

You add a list of your sites to the configuration in advance and set the frequency of checks. While you are in the world, the check will occur with a periodic frequency. If one or more sites are unavailable, you will receive a notification in the chat, accompanied by a characteristic sound

Setting up

After the first launch, a config folder will appear in your game folder, and in it - a mc-uptime.json file. This is where the setting up takes place. Here is an example of how to add your site there:

{
  "sites" : [
    {
      "id" : "Your Site Name",
      "url" : "https://example.com"
    }
  ],
  "cooldown" : 60
}

You can add more sites, their number is unlimited:

{
  "sites" : [
    {
      "id" : "Some Site",
      "url" : "https://example.com"
    },
    {
      "id" : "YouTube",
      "url" : "https://youtube.com"
    },
    {
      "id" : "Your Second Site",
      "url" : "https://ur-second-site.net"
    }
  ],
  "cooldown" : 120
}

cooldown - time between checks in seconds.
Please note that increasing the number of sites increases the overall time required for verification.

Frequently Asked Questions

MC Uptime server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.4). You can switch loaders with one click in the panel.

Is MC Uptime compatible with fabric?

MC Uptime officially supports fabric for Minecraft 1.21.4. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with MC Uptime – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if MC Uptime consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
