Description

Dashing widget to display a Jenkins build status and build progress

The widget is based on the meter-widget which is default in the Dashing installation

The widget can also see the progress of a "pre-build", i.e if you have a job triggering the actual build you want to define, you can configure this job in the jenkins_build.rb as a prebuild.

For more information, please see Coding Like a tosser

Installation

Put the files jenkins_build.coffee, jenkins_build.html and jenkins_build.scss goes in the /widget/jenkins_build directory and the jenkins_build.rb in the /jobs directory

Otherwise you can install this plugin typing:

dashing install GIST_ID

Usage (jenkins_build.rb)

Change the JENKINS_URI to your correct uri for Jenkins, eg.:

JENKINS_URI = URI.parse("http://ci.yourserver.com")

Add jenkins credential (if required) in JENKINS_AUTH, eg.:

JENKINS_AUTH = {
  'name' => 'username',
  'password' => 'password'
}

Put all the jobnames and pre job names in the job_mapping, eg.:

job_mapping = {
  'job1' => { :job => 'Job Name 1'},
  'job2' => { :job => 'Job Name 2', :pre_job => 'Job Name 3'},
}

Put the following in your dashingboard.erb file to show the status:

<li data-row="1" data-col="1" data-sizex="1" data-sizey="1">
  <div data-id="job1" data-view="JenkinsBuild" data-title="Build title" data-description="A little description of build" data-min="0" data-max="100"></div>
</li>

Multiple jobs can add in dashboard repeating the snippet and changing data-id in accord with job name specified in job_mapping. Widget support title and description via data attributes, this attributest can be omitted if you do not like to display this information.

    $(@node).fadeOut().css('background-color', @get('bgColor')).fadeIn()
    meter.attr("data-bgcolor", meter.css("background-color"))
    meter.attr("data-fgcolor", meter.css("color"))
    meter.knob()

  onData: (data) ->
    if data.currentResult isnt data.lastResult
      $(@node).fadeOut().css('background-color', @get('bgColor')).fadeIn()

Hi guys, can anyone suggest how to show recent 10 changes in a specific job in jenkins to dashing

Internet Archive link to the "Coding like a tosser" page: https://web.archive.org/web/20141021233221/http://steintoretosse.wordpress.com:80/2013/04/05/jenkins-build-status-widget-for-dashing/

Hey, great job it helps alot!
The only problem is that our jenkins is pretty busy and gets overwhelmed by the number of requests. We shortened your code a bit so we now have one request per job but the problem is still the same.
Is there a way to get information for multiple jobs out of a single request?
