FiveRuns Dash recipe for DataMapper

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

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

Installation

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

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

Compatibility

Currently only DataObject adapters are supported.

Configuration

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 issues: 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 :datamapper,
                          :url => 'http://dash.fiveruns.com',
                          :total_time => 'response_time'
