FiveRuns Dash recipe for ActiveRecord¶ ↑

Provides a Ruby API to push metrics from applications using ActiveRecord to the FiveRuns Dash service, dash.fiveruns.com, currently in beta.

You’ll need a Dash account before using this library.

This library is released as a gem from the official repository at github.com/fiveruns/dash-activerecord

sudo gem install fiveruns-dash-activerecord --source http://gems.github.com

Metrics in this recipe require a ‘total_time’ option be provided when the recipe is added; this option should indicate the metric to use when calculating % of utilization:

• For web applications, this is probably the total time of a request (ie, request_time)

• For daemons, this is likely a processing cycle (eg, proc_time)

Known issue: The metric name is not currently namespaced by recipe URL; although collision is unlikely, if your ‘total_time’ setting is for a metric that’s present in more than one recipe, you may encounter problems.

Note: The metric selected must be ‘marked’, ie:

recipe.time :response_time, :method => 'Request#dispatch_action',
                            :mark => true

Example:

other_recipe.add_recipe :activerecord,
                        :url => 'http://dash.fiveruns.com',
                        :total_time => 'response_time'

See the Dash Ruby support pages support.fiveruns.com/faqs/dash/ruby for more information on how to use this library.
