AppSignal Logging gives you 360-degree insights into your application's performance. To help give you those insights, we wanted to ensure our logging solution allowed you to send AppSignal your logs your way. You can now use Winston transport to send your Node.js application's logs directly to AppSignal and take advantage of having access to all of your application's performance logs and metrics in one place.
