⚠️ Bare minimum code to explore Amazon CloudWatch Embedded Metrics with Ruby. Any and all help welcome to raise the quality of our implementation.

Enhancing workload observability using Amazon CloudWatch Embedded Metric Format

Pulled from these two projects using the Embedded Metric Format Specification as a reference guide.

• Node: https://github.com/awslabs/aws-embedded-metrics-node
• Python: https://github.com/awslabs/aws-embedded-metrics-python

However, unlike these projects, we differ in the following ways. Again, contributions are very much welcome if you want to see more or change this.

• Initial focus on Lambda. No other sinks.
• As such, no default Dimensions or Configuraiton for:
  • LogGroupName
  • LogStreamName
  • ServiceName
  • ServiceType

Add this line to your application's Gemfile:

gem 'aws-embedded-metrics-customink'

Simple configuration.

Aws::Embedded::Metrics.configure do |c|
  c.namespace = 'MyApplication'
end

Usage is in a scope block. All metrics are flushed afterward

Aws::Embedded::Metrics.logger do |metrics|
  metrics.put_dimension 'SomeDimension', 'SomeDimensionValue'
  metrics.set_property  'EventKey', 'some/s3/path'
  metrics.put_metric    'Processor', 232, 'Milliseconds'
  metrics.put_metric    'Total', 4008, 'Milliseconds'
end

After checking out the repo, run bin/setup to install dependencies. Then, run bin/test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
