How to do Structured Logging and Custom Metrics in your Serverless Applications?

Most of AWS services emit basic metrics to Cloudwatch. It is a good practice in distributed application to add additional metrics including business and operational ones to understand how the application is doing.
Structured logging means having a consistent log format and structure - so then we can query the logs easily. This is also related to a central logging system. It is important to have all your logs in one place, it can be Cloudwatch or any other 3rd Party system. I will be talking about cloudwatch logs as it is the one that comes with AWS, but there are many tools out there.
Embedded metric library is a an implementation of the Cloudwatch embedded metric format, that is available for many clients.

very useful ❤️

Glad you think so!

Everything this video shows didn't work for me until I turned on 'CloudWatch Lambda Insights', part of 'Enhanced Monitoring' config of the lambda function. Dunno why posting custom metrics would have to be tied to that.

Great content! Reading the documentation on embedded metrics did not help me at all, your video though just made it click.
