Temporary Alternative临时替代方案¶
The Node.js team is currently working on rewriting the logger. Node.js团队目前正在重写记录器。In the meantime, you can output monitor events using the following snippet:同时，您可以使用以下代码段输出监控器事件：
const uri = "mongodb+srv://<user>:<password>@<cluster-url>?writeConcern=majority";
const client = new MongoClient(uri, { monitorCommands:true });
client.on('commandStarted', (event) => console.debug(event));
client.on('commandSucceeded', (event) => console.debug(event));
client.on('commandFailed', (event) => console.debug(event));
