Confused on Formatting

I am trying to wrap my head around how it pulls the data but have not been able to figure it out, lets say I want to pull the shard name and uptime stats from this code, how can that be done? If I can figure that out then I would be good on the rest.

{
  "server": {
    "name": "Name",
    "host": "127.0.0.1",
    "port": 7057,
    "os": "Microsoft Windows NT 10.0.17763.0",
    "net": "4.0.30319.42000",
    "core": "RunUO",
    "assembly": "ServUO",
    "assembly_version": "0.5.8002.30674"
  },
  "stats": {
    "uptime": "3.17:18:38.6457664",
    "uptime_stamp": 321518.6457664,
    "uptime_peak": "3.17:18:38.6460000",
    "uptime_peak_stamp": 321518.646,
    "online": 1,
    "online_max": 1,
    "online_peak": 1,
    "unique": 1,
    "unique_max": 1,
    "unique_peak": 1,
    "items": 149729,
    "items_max": 149729,
    "items_peak": 149729,
    "mobiles": 3527,
    "mobiles_max": 3527,
    "mobiles_peak": 3527,
    "guilds": 0,
    "guilds_max": 0,
    "guilds_peak": 0,
    "memory": 408354992,
    "memory_max": 411494912,
    "memory_peak": 411494912
  }
}

This is what I was testing and it didn’t work:

{subloop-array:stats:-1}
{stats.uptime}
{stats.uptime_stamp}
{stats.uptime_peak}
{/subloop-array:stats}
