What is Galicaster Dashboard ?Galicaster Dashboard is a web-based solution to monitor and manage large fleets of Capture Agents. Galicaster Dashboard takes advantage of the Opencast Matterhorn capture agent API, so any agent implementing it can be accessed by the Dashboard, including Galicaster and the standard capture agent. Its main features are:
First Alpha version - now available!The first demo version of Galicaster Dashboard is already available! Please follow the installation instructions to try it in your system. View modesGalicaster Dashboard provides two views: a panel view to monitor your agents providing auto-refreshed screenshots and basic data, and a calendar view, where the recording schedule can be easily checked and modified. In both cases, the agents on the screen can be filtered according to different criteria, so that only the relevant information is displayed. Panel ViewThe panel view is aimed to monitor the agents in your installation. Agents can be filtered by their status or their upcoming events, and also hidden at will. Screenshots are refreshed automatically. The panel view has two layouts:
Mosaic layoutFrom the mosaic view we can see the agent status with a preview (screenshot) of their UI. The following actions are available by pressing on the different buttons on the screen:
Table layoutThe table layout provides a more detailed collection of information including: duration of the last recording, next recording, free disk space, audio and video feedback, etc. There are also shortcuts to a detailed view of the agent's screen and tools to review the agent configuration, logs and access via ssh (coming soon!). Agent ViewThe agent view displays a screenshot of the agent's interface (updated automatically), and a table with useful information including the current loaded profile. There are also shortcuts to other tools available also in the table layout. Calendar ViewThe calendar provides an interface to browse and review the recordings in your capture agents. |

Installation instructions
External dependencies
Most of the functionalities in the Dashboard will work out-of-the-box, but the screenshot extraction has an external dependency with GStreamer. Additionally, the command-line utility gst-launch and the "good" and "bad" plugins must be installed. Versions above 0.10.29 are proven to work. Older releases may or may not work.
GStreamer in CentOS CentOS includes a very old version of GStreamer in its official repository, which will not work for Galicaster Dashboard. In this case, we recommend using the Matterhorn RPM repository kindly provided by the University of Osnabrück. |
Bundle installation
The Dashboard is packaged as a Matterhorn bundle, so it can be easily deployed in any Matterhorn installation. Since it depends on certain Matterhorn services to work, it must be installed in the admin server. In the following steps, ${MH_SRC} denotes the directory where the Matterhorn source code is, and ${FELIX_HOME} the directory where the Felix instance is installed (for Matterhorn versions under or equal to 1.3).
- Download the tarball and uncompress it in your ${MH_SRC}/modules directory. If you use a shell, this can be done by:
wget http://webfiler.teltek.es/webfiler/galicaster/GalicasterDashboard-alpha.tgz
tar -C ${MH_SRC}/modules GalicasterDashboard-alpha.tgz - Make sure your current Matterhorn version matches the one in the Dashboard pom.xml file:
- Check your exact Matterhorn version by examining the first <version> tag within the ${MH_SRC}/pom.xml file.
- Substitute that value in the <matterhorn.version> tags within the Dashboard pom.xml file.
- You can do this in one step by running the following command from within the ${MH_SRC}/modules/galicaster-dashboard directory (the one you have just clone'd from git):
cd ${MH_SRC}/modules/galicaster-dashboard
sed -i "/<matterhorn.version>[^>]+<\/matterhorn.version>/s//<matterhorn.version>$(grep -m 1 "<version>" ../../pom.xml | cut -d'>' -f2 | cut -d'<' -f1)<\/matterhorn.version>/" pom.xml
- Compile the bundles with Maven:
- 1.3 and earlier:
cd ${MH_SRC}/modules/galicaster-dashboard
mvn clean install -DdeployTo=${FELIX_HOME}/matterhorn - 1.4 and above:
cd ${MH_SRC}/modules/galicaster-dashboard
mvn clean install -DdeployTo=${MH_SRC}
- 1.3 and earlier:
- If maven returns with no errors, the Dashboard should be available at:
http://your-server-url/dashboard/index.html.
Configuration
The Dashboard service configuration file should be located in $MH_ROOT/etc/services/org.galicaster.dashboard.DashboardService.properties. It will not exist the first time you use the Dashboard, but the service will work correctly even if the file does not exist. Therefore, you may create the file only if you need to specify some of the configuration properties allowed by the service.
Those properties are:
- agent.<agent_name>.vnc.password: This property sets up the password required to establish a VNC connection with the agent <agent_name>.
- default.vnc.password: This property sets up a global password, which is only used when a certain agent's password is not explicitly defined.
The following example illustrates how the properties defined above are used:
When the Dashboard needs to establish a VNC connection with the agent GC-example, the password used will be, in that order:
- If defined, the value of agent.GC-example.vnc.password.
- If defined, the value of default.vnc.password.
- No password will be used.
