The wrapper you put around your Lambda event handler instruments your code so that asynchronous messages are sent to IOPipe each time your code makes an action. This data is recorded and cataloged to enable a variety of reports and alerts. With Node.js, you can review the IOPipe package located at https://www.npmjs.com/package/@iopipe/iopipe. The source code can be found in this book's GitHub repository at https://github.com/iopipe/iopipe-js.

As an Advanced AWS Technology Partner, and as a DevOps competency holder, IOPipe's architecture, which naturally runs on AWS, has been audited for best practices around security and reliability, so you can rest assured that the data being emitted by your lambda functions is safe and secure.

We will study some more functions in the following subsections:

• Metrics dashboards
• Alerting
• Profiling
