Mysql2::Metrics

Instrument mysql2 queries.

Add this line to your application's Gemfile:

gem 'mysql2-metrics'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mysql2-metrics

Just require mysql2/metrics in addition to mysql2, ans use mysql2 as usual.

require 'mysql2'
require 'mysql2-metrics'

client = Mysql2::Client.new(:host => "localhost", :username => "root", :database => "test")
results = client.query("CREATE TABLE IF NOT EXISTS test (id INT)")

This will output a measured time to STDOUT as:

time:2014-11-02T01:38:25+09:00  query:CREATE TABLE IF NOT EXISTS test (id INT)  elapsed:0.000299591

where elapsed is the elapsed time in second.
