      Retours :

      • Stat : Les statistiques du serveur récupérées.

      let resp = await conn.stats();
      console.log("CPU usage:", resp.data.cpuUsage);
      console.log("Memory usage:", resp.data.memUsage);
      console.log("Expiration date:", resp.data.expiredDate);
      console.log("CPU cores:", resp.data["cpuCores"]),
      console.log("Company:", resp.data["company"]),
      console.log("Server type:", resp.data["serverType"]),
      console.log("Version:", resp.data["version"]);
      

      CPU usage: 12.503961
      Memory usage: 10356.265625
      Expiration date: Thu Dec 26 23:59:59 2024
