本节为您介绍如何使用Connection对象的方法检查数据库服务器统计信息。

stats()

获取数据库服务器的统计信息。

参数：

• RequestConfig（可选）：请求配置。

返回值：

• Stat：获取到的服务器统计信息。

  let password = "***";
  let connPool = new ConnectionPool(hosts, username, password);

  // 建立与数据库的连接
  let conn = await connPool.getActive();

  // 配置请求
  let requestConfig = <RequestType.RequestConfig>{
    useMaster: true,
  };

  // 服务器信息
  let resp = await conn.stats();

  console.log("Memory usage:", resp.data.memUsage);
  console.log("Expiration date:", resp.data.expiredDate);
