Note: This is a version of the opentelemetry-instrumentation-grape v0.1.4 gem modified to run on Ruby 2.6 and up. This has been given the version number v0.0.1.4.
This version of the gem requires the opentelemetry-instrumentation-rack v0.23.4 that was modified to run on Ruby 2.6, versioned v0.22.23.4. This modded gem can be found at https://github.com/LoyalSphere/opentelemetry-instrumentation-rack-ruby2.6-experimental
The Grape instrumentation is a community-maintained instrumentation for Grape, a REST-like API framework for Ruby.
It relies on the Grape built-in support for ActiveSupport::Notifications
(more info here) and the OpenTelemetry Rack instrumentation.
It currently supports the following events:
endpoint_run.grape
endpoint_render.grape
endpoint_run_filters.grape
format_response.grape
Install the gem using:
gem install opentelemetry-instrumentation-grape
Or, if you use bundler, include opentelemetry-instrumentation-grape
in your Gemfile
.
To use the instrumentation, call use
with the name of the instrumentation:
OpenTelemetry::SDK.configure do |c|
c.use 'OpenTelemetry::Instrumentation::Grape'
end
Grape is "designed to run on Rack or complement existing web application frameworks such as Rails and Sinatra". As a result, this instrumentation uses the Rack instrumentation and modifies the Rack spans, modifying the span name and adding Grape attributes and events. It is recommended to use it along with Rails and/or Sinatra instrumentations, if any of these frameworks are being used.
Alternatively, you can also call use_all
to install all the available instrumentation.
OpenTelemetry::SDK.configure do |c|
c.use_all
end
Indicate if any events should not produce spans.
- Accepted values:
:endpoint_render
,:endpoint_run_filters
,:format_response
. - Defaults to
[]
(no ignored events).
Example:
OpenTelemetry::SDK.configure do |c|
c.use 'OpenTelemetry::Instrumentation::Grape', { ignored_events: [:endpoint_run_filters] }
end
Note that the endpoint_run
event cannot be ignored. If you need to disable the instrumentation, set :enabled
to false
:
OpenTelemetry::SDK.configure do |c|
config = { 'OpenTelemetry::Instrumentation::Grape' => { enabled: false } }
c.use_all(config)
end
Example usage can be seen in the ./example/trace_demonstration.rb
