Fix build on ARM64 Linux and other improvements

Added

• Add activate_if_environment helper for Appsignal.configure. Avoid having to add conditionals to your configuration file and use the activate_if_environment helper to specify for which environments AppSignal should become active. AppSignal will automatically detect the environment and activate itself it the environment matches one of the listed environments.

  Ruby

  # Before
  Appsignal.configure do |config|
    config.active = Rails.env.production? || Rails.env.staging?
  end
   
  # After
  Appsignal.configure do |config|
    # Activate for one environment
    config.activate_if_environment(:production)
   
    # Activate for multiple environments
    config.activate_if_environment(:production, :staging)
  end

• Add a hostname AppSignal tag automatically, based on the OpenTelemetry host.name resource attribute. (Beta only)

• Add incident error count metric for enriched OpenTelemetry traces. (Beta only)

• Set the app revision config option for Scalingo deploys automatically. If the CONTAINER_VERSION system environment variable is present, it will use used to set the revision config option automatically. Overwrite it's value by configuring the revision config option for your application.

Changed

• Ignore the Rails healthcheck endpoint (Rails::HealthController#show) by default for Rails apps.

  If the ignore_actions option is set in the config/appsignal.yml file, the default is overwritten. If the APPSIGNAL_IGNORE_ACTIONS environment variable is set, the default is overwritten. When using the Appsignal.configure helper, add more actions to the default like so:

  Ruby

  # config/appsignal.rb
  Appsignal.configure do |config|
    # Add more actions to ignore
    config.ignore_actions << "My action"
  end

  To overwrite the default using the Appsignal.configure helper, do either of the following:

  Ruby

  # config/appsignal.rb
  Appsignal.configure do |config|
    # Overwrite the default value, ignoring all actions ignored by default
    config.ignore_actions = ["My action"]
   
    # To only remove the healtcheck endpoint
    config.ignore_actions.delete("Rails::HealthController#show")
  end

Fixed

• Fix an issue where the extension fails to build on ARM64 Linux.
