Function metrics, easier AWS credential setup, and Lambda versioning in Serverless Framework v1.3

We're proud to release the Serverless Framework v1.3.0 today.

Highlights of 1.3.0

Let's take a look at the highlights of this release. You can find a list with all the updates in the changelog.

Function Metrics

Ever wondered how your functions are performing? The new serverless metrics allows you to see all the function metrics, such as invocations, throttles, errors, and duration, at a glance.

Just type

serverless metrics --function myFunction

to see the metrics of the last 24h for your function myFunction.

You can even specify the timeframe you want to see for the metrics with the startTime and endTime options.

For example,

serverless metrics --function myFunction --startTime 2016-11-28 --endTime 2016-12-02

will show you all the metrics between Nov. 28th and Dec. 2nd.

You can read more about the new metrics functionality in the documentation.

AWS Credentials Setup

Setting up credentials should be streamlined in the overall Serverless experience. V1.3 adds a new command called serverless config credentials that helps you setup your AWS credentials on your local machine.

This example will setup the default AWS profile with the provided key and secret:

serverless config credentials --provider aws --key someKey --secret someSecret

No need to configure the credentials file through the aws-cli anymore.

You can read more about the new config functionality in the documentation.

Lambda Versioning

Serverless now supports automatic Lambda versioning with the help of the built-in Lambda versions AWS provides.

Keeping a history of all of your deployed Lambda functions is an important feature. AWS will now use your Lambda version in the logs, as well. This makes it way easier to track down bugs.

You don't need to change anything. Just deploy your service as usual and Serverless will version your Lambda functions from now on.

Refactorings and Bug Fixes

We've also fixed a bunch of bugs (thanks for bringing them up!), and have continued our process of codebase refactorings so that it's easier for new contributors to get on board.

Next Steps

We've already started filling in the next milestones. Check out the 1.4 milestone to see what you can expect in two weeks.

We hope that you have fun with the new release! Let us know if you have any questions or feedback in our Forum or GitHub Issues.

Using Semver

Note that we're using strict Semver for our Serverless Framework versioning. This way you'll know when we introduce major features or breaking changes.
