OpenTelemetry Mysql2 Instrumentation

The OpenTelemetry Mysql2 Ruby gem is a community maintained instrumentation for Mysql2.

How do I get started?

Install the gem using:

gem install opentelemetry-instrumentation-mysql2

Or, if you use bundler, include opentelemetry-instrumentation-mysql2 in your Gemfile.

Usage

To use the instrumentation, call use with the name of the instrumentation:

OpenTelemetry::SDK.configure do |c|
  c.use 'OpenTelemetry::Instrumentation::Mysql2'
end

Alternatively, you can also call use_all to install all the available instrumentation.

OpenTelemetry::SDK.configure do |c|
  c.use_all
end

The mysql2 instrumentation allows the user to supply additional attributes via the with_attributes method. This makes it possible to supply additional attributes on mysql2 spans. Attributes supplied in with_attributes supersede those automatically generated within mysql2's automatic instrumentation. If you supply a db.statement attribute in with_attributes, this library's :db_statement configuration will not be applied.

require 'opentelemetry/instrumentation/mysql2'

client = Mysql2::Client.new(:host => "localhost", :username => "root")
OpenTelemetry::Instrumentation::Mysql2.with_attributes('pizzatoppings' => 'mushrooms') do
  client.query("SELECT 1")
end

Configuration options

OpenTelemetry::SDK.configure do |c|
  c.use 'OpenTelemetry::Instrumentation::Mysql2', {
    # The obfuscation of SQL in the db.statement attribute is enabled by default.
    # To disable, set db_statement to :include; to omit the query completely, set db_statement to :omit
    db_statement: :include,
  }
end

Examples

An example of usage can be seen in example/mysql2.rb.
