Sequel::Instrumentation

This gem provides OpenTracing instrumentation for Sequel using Dataset and Database extensions.

Add this line to your application's Gemfile:

gem 'signalfx-sequel-instrumentation'

And then execute:

$ bundle

Or install it yourself as:

$ gem install signalfx-sequel-instrumentation

require 'sequel/instrumentation'

Sequel::Instrumentation.instrument(tracer: OpenTracing.global_tracer)

Optional argument:

• tracer: used to set a custom tracer. Default: OpenTracing.global_tracer

Each span generated by the instrumentation will have the following tags:

• component: ruby-sequel
• span.kind: client
• db.type: the database driver type. For example, mysql2
• db.statement: the SQL statement being executed

When possible, the db.instance tag will also be populated with the database name.

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