Logging
On this page
This version of the documentation is archived and no longer supported. View the current documentation to learn how to upgrade your version of the Node.js driver.
Important
The driver doesn't use the logger in versions 4.0 and later. Attempting to use prior logger settings in this version won't print anything in the log.
Instead, see our monitoring guides:
Temporary Alternative
The Node.js team is currently working on rewriting the logger. In the meantime, you can output monitor events using the following snippet:
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));
