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.
