Unreleased

0.13.1 - 2024-10-11

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 - 2024-10-02

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 - 2023-07-28

Added

  • Summary metric type (mostly for Prometheus adapter).

0.11.0 - 2021-09-25

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 - 2021-08-30

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 - 2021-07-21

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 - 2021-05-07

Added

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

0.8.0 - 2020-08-21

Added

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

0.7.0 - 2020-08-07

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 - 2020-08-04

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

0.6.1 - 2020-07-16

Fixed

0.6.0 - 2020-07-15

Added

  • Yabeda.with_tags to redefine default tags for limited amount of time–for all metrics measured during a block execution. @Envek

Fixed

  • Default tags were not sent to adapters for metrics declared before default_tag declaration. @Envek

0.5.0 - 2020-01-29

Added

  • Ability to specify aggregation policy for metrics collected from multiple process and exposed via single endpoint. @Envek

    For now it is only used by yabeda-prometheus when official Prometheus client is configured to use file storage for metrics.

0.4.0 - 2020-01-28

Changed

  • Configuration of gem was changed from synchronous (at the moment when configure block was executed) to postponed (only on configure! method call). @Envek

    This should allow to fix problems when metrics from gems are registered too early, before required changes to the monitoring system clients.

0.3.0 - 2020-01-15

Added

  • Ability to specify default tag which value will be automatically added to all metrics. #7 by @asusikov.

0.2.0 - 2020-01-14

Added

  • Ability to specify an optional list of allowed tags as an option to metric declaration. @Envek

    Some monitoring systems clients (like official prometheus client for Ruby) require to declare all possible metric labels upfront.

0.1.3 - 2018-12-18

Added

  • Block-based DSL for defining groups and metrics. @DmitryTsepelev

0.1.2 - 2018-10-25

Fixed

0.1.1 - 2018-10-17

Changed

  • Renamed evil-metrics gem to yabeda. @Envek

0.1.0 - 2018-10-03

  • Initial release of evil-metrics gem. @Envek
