cc_dashboard - Aggregates the build status of projects from multiple CruiseControl servers on to a single "dashboard" web page
cc_dashboard will combine the build status of projects from multiple CruiseControl servers (actually, from any Continuous Integration server that exposes build status information using the "cctray xml format" - see below) on to a single "dashboard" web page.
cc_dashboard is a Rails 3.2 application. It has been tested against Ruby 1.9.3, but because it is very, very simple it should run under earlier versions of 1.9. (Rails 3.1 dropped support for Ruby 1.8.7.)
As the number of Rails projects I was using increased I was then forced to split them amongst multiple CruiseControl.rb servers to improve build times. However, I now had the problem of monitoring multiple CruiseControl.rb servers. So the answer was to aggregate all the build status using cc_dashboard!
Why did I write it in Rails? Because I was working with a large number of Rails projects at the time and had the Rails infrastructure in place to host cc_dashboard!
(Another approach to this problem could have been to use continuous integration servers that support master/multiple slaves configurations like Jenkins, but it wasn't an options at the time.)
Assuming you have the base Rails gems installed (no database needed):
Install ruby 1.9.2 or later and bundler
Unpack the cc_dashboard zip/tar
Create a config/cc_dashboard_config.rb file with a list servers from which to fetch "cctray xml format" (see below) feeds. You can use config/cc_dashboard_config.rb.example as a template
Install the dependent gems by doing a bundle install
Start the cc_dashboard Rails server by running the start.sh script
Point your web browser at the application root. e.g.
To stop the cc_dashboard Rails server run the stop.sh script.
Note to Rails gurus: The start.sh and stop.sh scripts use Unicorn, but if you like you can use Webrick (e.g. "rails server -p 3332 -e production"), or Thin, or you can deploy behind Passenger, or use whatever server you like. You can also bind to whatever TCP port you like.
cc_dashboard has support for changing the look, or "skin", of its dashboard page.
Available skins are:
- doom - yep, the original first-person shooter Doom
- hudson - some images borrowed from the Hudson continuous integration server
- iskin - all things Apple and the cult of Steve Jobs
- kitten - aaawww, how cute :)
- minimal - a very, very basic skin if you don't appreciate art
- nightmare - primarily Nightmare on Elm Street, but throw in some other horror schlock from Jason vs Freddy, Chucky, etc
- spaceinvaders - yep, the arcade classic
- worldcup - a.k.a. soccer
You choose the skin by setting the DashboardConfig.skin value in the config/cc_dashboard_config.rb configuration file. You can also choose the skin per-HTTP-request by adding a "?skin=SKIN" to the end of the URL (e.g. "?skin=hudson").
To make the dahsboard a little less boring you can add some "bling". Built-in blings are:
- cheezburger - a random image from the Cheezburger Network
- chucknorris - Chuck Norris is the ultimate programmer!
You choose the bling by setting the DashboardConfig.bling value in the config/cc_dashboard_config.rb configuration file. You can also choose the bling per-HTTP-request by adding a "?bling=BLING" to the end of the URL (e.g. "?bling=cheezburger").
cc_dashboard can play sounds to alert you when:
- a build breaks
- a build is still broken
- a build was broken but is now fixed
Available tracks are:
- aliens - sound bites from the classic "Aliens" movie. Game over!
- itrack - some wisdom from Steve Jobs
- nightmare - sound bites from the schlock horror movies like Nightmare on Elm Street and Saw
- simpsons - sound bites from the animated "satirical parody of a middle class American lifestyle" sitcom. Doh!
- south_park - safe for work sound bites from the cartoon that kicks ass!
You choose the track by setting the DashboardConfig.track value in the config/cc_dashboard_config.rb configuration file, or leave the configuration commented out to disable sounds. You can also choose the track per-HTTP-request by adding a "?track=TRACK" to the end of the URL (e.g. "?track=aliens").
NOTE: Tracks will only work on browsers that support the HTML5 audio and storage APIs. WAVs seem to be the most widely supported cross-browser audio format.
It can be helpful to get a reminder for upcoming important events of the day, such as the Daily Standup. cc_dashboard can be configured to display a clock and an audible alarm - either a text-to-speech mesage (see note on speak.js) or a '24' digital clock 'plink' sound - to help remind you of these events.
See the DashboardConfig.alarm section in the config/cc_dashboard_config.rb configuration file for examples. More than one alarm can be configured.
NOTE: Alarms will only work on browsers that support HTML 5 audio and @font-family.
You can display a number of widgets - which can show all sorts of useful information such as the weather forecast - at the bottom right of the dashboard.
- weather_clock - Displays the current time and weather forecast. The browser's geo location is determined using the Yahoo! PlaceFinder API and the forecast is fetched every hour from the Yahoo! Weather RSS Feed.
See the DashboardConfig.widgets section in the config/cc_dashboard_config.rb configuration file for examples.
"cctray xml format"
Originally developed for CruiseControl.NET, the "cctray xml format" is an RSS-like way of exposing the build status of projects. This format has caught on and is now supported by a number of continuous integration servers:
- CruiseControl.rb - http://cc.rb.servername:3333/XmlStatusReport.aspx
- CruiseControl - http://cc.java.servername:8080/cctray.xml
- CruiseControl.NET - http://cc.net.servername/XmlStatusReport.aspx
- Jenkins - http://jenkins.servername:8080/cc.xml
- Hudson - http://hudson.servername:8080/cc.xml
- Travis CI - http://travis-ci.org/ownername/repositoryname/cc.xml
- Bamboo - https://build.springsource.org/rss/createAllBuildsRssFeed.action?feedType=rssAll&os_authType=basic (NOTE: Bamboo does not output build status in cctray format, but instead has its own RSS format - see below)
See Multiple Project Summary Reporting Standard for details of the cctray XML feed format (or see a copy of this doco in the next section below). This doco is mostly correct, the only difference i've seen "in the wild" are:
- An additional "Pending" activity
- An additional "Unknown" status. I've seen Unknown reported by CruiseControl.rb when project builds are serialized ("Configuration.serialize_builds = true" set in .cruise/site_config.rb) and one build is waiting for another build to finish. I've seen Unknown reported by Hudson when a project is disabled.
btw, cctray is a .NET application that sits in your Windows system tray and can alert you via popups or sounds when a project build is successful or fails. It is available as part of a CruiseControl.NET release.
ccmenu is a cctray equivalent for the Mac.
Bamboo RSS feed
Bamboo does not output build status in cctray format, but it is a common enough CI server that it was a no brainer to add support for.
Bamboo has its own proprietary RSS format, an example of which can be viewed here. An important difference to note between the Bamboo RSS feed and a cctray feed is that the Bamboo RSS feed outputs the status of the last, say, 20 builds (it's configurable) and not the current status of all configured projects. This means that if a particular project does not build for a long time that project may "drop out" of the RSS feed until it builds again. Bummer, but that's the way it is.
Multiple Project Summary Reporting Standard
NOTE: This is a copy of Multiple Project Summary Reporting Standard which I include here because that wiki often seems to be down.
Various Continuous Integration monitoring / reporting tools exist. Examples are:
These tools work by polling Continuous Integration servers for summary information and presenting it appropriately to users.
If a Continuous Integration server can offer a standard summary format, and a reporting tool can consume the same, then we get interoperability between reporting tools and CI Servers.
Summary information will be available as a plain XML string retrievable through an http GET request.
The format of the XML will be as follows:
A single node, the document root, which contains 0 or many node.
Each may have the following attributes:
<tbody> <tr> <th> name </th> <th> description </th> <th> type </th> <th> required </th> </tr> <tr> <td> name </td> <td> The name of the project </td> <td> string </td> <td> yes </td> </tr> <tr> <td> activity </td> <td> The current state of the project </td> <td> string enum : Sleeping, Building, CheckingModifications <br clear="all" /> </td> <td> yes </td> </tr> <tr> <td> lastBuildStatus </td> <td> A brief description of the last build </td> <td> string enum : Success, Failure, Exception, Unknown </td> <td> yes </td> </tr> <tr> <td> lastBuildLabel </td> <td> A referential name for the last build </td> <td> string </td> <td> no </td> </tr> <tr> <td> lastBuildTime </td> <td> When the last build occurred </td> <td> DateTime </td> <td> yes </td> </tr> <tr> <td> nextBuildTime </td> <td> When the next build is scheduled to occur (or when the next check to see whether a build should be performed is scheduled to occur) </td> <td> DateTime </td> <td> no </td> </tr> <tr> <td> webUrl </td> <td> A URL for where more detail can be found about this project </td> <td> string (URL) </td> <td> yes </td> </tr> </tbody>
Clients that consume this XML should not rely on any optional attribute being present, and should degrade their functionality gracefully.

CruiseControl.rb cctray times in the wrong timezone bug
CruiseControl.rb versions 1.4.0 and 1.3.0 (and probably earlier versions) incorrectly report local server time as UTC in the cctray feeds. To fix change the following method in lib/time_formatter.rb
def round_trip_local(time) time.strftime('%Y-%m-%dT%H:%M:%S.0000000-00:00') # yyyy'-'MM'-'dd'T'HH':'mm':'ss.fffffffK) end
def round_trip_local(time) time.xmlschema end
cc_dashboard has been tested successfully against Chrome 17.0, Firefox 11, Internet Explorer 7 and Internet Explorer 8.
cc_dashboard does not render correctly using Internet Explorer 6 and I have no intention of supporting IE6 :)
