test_fnmetric.rb

require "rubygems"
require "bundler/setup"

require "fnordmetric"

FnordMetric.options = {
  :redis_url => 'redis://:s3cr3t@127.0.0.1:6379/10'
}

FnordMetric.namespace :myapp do

  # render a timeseries graph
  widget 'Sales',
    :title => "Sales per Minute",
    :gauges => [:sales_per_minute],
    :type => :timeline,
    :width => 100,
    :autoupdate => 1

end

FnordMetric.standalone

Sinatra gives me the error message:

Redis::CommandError at /myapp
ERR operation not permitted

Same here. Have you been able to get fnord working with authentication?
