Puma::NewRelic

This is a Puma plugin for NewRelic custom metrics. It will sample the Puma stats and create a custom metric for NewRelic. You can view the information in the NewRelic insights or in NewRelic One.

Add this line to your application's Gemfile:

gem 'puma-newrelic'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install puma-newrelic

• Install the gem
• Add plugin 'new_relic_stats' to your puma.rb
• Create a dashboard on the NewRelic insights or NewRelic One

NQRL example:

SELECT rate(average(newrelic.timeslice.value), 1 minute) 
FROM Metric 
WHERE appName ='My App Name' 
WITH METRIC_FORMAT 'Custom/Puma/pool_capacity' 
TIMESERIES FACET `host` LIMIT 10 SINCE 1800 seconds ago

common: &default_settings
    puma:
      sample_rate: 15
      keys:
        - backlog
        - running
        - pool_capacity
        - max_threads

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec 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.
