0.13.1: Fix Ruby 2.x compatibility

Fixed

• Compatibility with Ruby 2.x, broken in 0.13.0 due to differences of keywords handling in Ruby 2.x for case when method has arguments with default values. [@Envek]

0.13.0: Limit metrics to specific adapters, optional tags for counters

Added

• Ability to limit some metrics to specific adapters. #37 by [@Keallar] and [@Envek]

  Yabeda.configure do
    group :cloud do
      adapter :newrelic, :datadog
  
      counter :foo
    end
  
    counter :bar, adapter: :prometheus
  end

• Multiple expectations in RSpec matchers. [@Envek]

  expect { whatever }.to increment_yabeda_counter(:my_counter).with(
    { tag: "foo" } => 1,
    { tag: "bar" } => (be >= 42),
  )

Changed

• Don't require to provide tags for counters and histograms, use empty tags ({}) by default. See discussion at #26. [@Envek]

  Yabeda.foo.increment
  # same as
  Yabeda.foo.increment({}, by: 1)

Fixed

• Railtie loading to prevent calling methods that have not yet been defined. #38 by [@bibendi].

0.12.0: Summary metric type

Added

• Summary metric type (mostly for Prometheus adapter).

0.11.0: Test adapter and RSpec matchers

Added

• RSpec matchers increment_yabeda_counter, update_yabeda_gauge, and measure_yabeda_histogram for convenient testing. #25 by [@Envek][]
• Automatic setup of RSpec on require "yabeda/rspec"
• Special test adapter that collects metric changes in memory

0.10.1: Fix compatibility with anyway_config 1.x on Ruby older than 2.5

Fixed

• Compatibility with anyway_config 1.x gem (which is automatically used on older Rubies, older then minimal Ruby 2.5 for anyway_config 2.x)

0.10.0: Debug mode and histograms measuring block runtime

Added

• Ability to pass a block to Yabeda::Histogram#measure to automatically measure its runtime in seconds using monotonic time.
• Debug mode that will enable some additional metrics to help debug performance issues with your usage of Yabeda (or Yabeda itself). Use environment variable YABEDA_DEBUG to enable it or call Yabeda.debug!.
• Debugging histogram yabeda_collect_duration that measures duration of every collect block, as they are used for collecting metrics of application state and usually makes some potentially slow queries to databases, network requests, etc.

Changed

• Adapters now should use method Yabeda.collect! instead of manual calling of every collector block.

0.9.0: Ability to add default tags only for a specific group

Added

• Ability to set global metric tags only for a specific group #19 by [@liaden]

0.8.0: Automatic configuration on Rails (moved from yabeda-rails)

Added

• Added railtie to automatically configure Yabeda on Rails: moved from yabeda-rails gem. @Envek

0.7.0: increment and decrement convenience methods for gauges

Added

• #increment and #decrement convenience methods for Yabeda::Gauge. #13 by @dsalahutdinov
• Ability to use custom step in #increment and #decrement for gauges. @Envek

Fixed

• Account for default tags in Yabeda::Metric#get. @Envek

0.6.2: Fix compatibility with yabeda-puma-plugin

Fixed

• Compatibility with plugins (like yabeda-puma-plugin) that for some reason configures itself after Yabeda configuration was already applied by Yabeda.configure! (was broken in 0.6.0). @Envek
