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.

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.

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.
