B.14.2 Activating the HP Insight CMU GUI
The HP Insight CMU GUI runs on the HP Insight CMU client and can be launched two ways:
•
Through the client web browser by connecting to the HP Insight CMU management server
•
By copying the HP Insight CMU GUI Java file onto the client
Launching the HP Insight CMU GUI using a web browser
The HP Insight CMU GUI is a Java application that can be downloaded from the web server running
on the HP Insight CMU management node by using Webstart. Using the HP Insight CMU client
web browser, the HP Insight CMU GUI can be accessed remotely and launched automatically on
the client workstation. This capability enables access to the HP Insight CMU GUI from any
workstation.
HP Insight CMU automatically starts a minimal web server on port 80 of the management node
that serves only the HP Insight CMU website. If an HTTP service is already running on this port on
the management node, then the HP Insight CMU web service does not run. If you want to use a
different port number, then edit the environment variable CMU_THTTPD_PORT in the /opt/cmu/
etc/cmuserver.conf
file.
To launch the HP Insight CMU GUI:
1. Start a web browser on the HP Insight CMU client and then enter:
http://cmu-management-node-ip-addr
2. From the main menu of the HP Insight CMU v7.1 website, click Launch Cluster Management
Utility GUI.
Launching the HP Insight CMU directly from the Java file
You can run the HP Insight CMU GUI directly from the Java file cmugui.jar. This file is in the
/opt/cmu/bin
directory on the management node. Copy the file anywhere on the GUI client
node.
To launch the client:
•
On Windows operating systems: double-click the copied cmugui.jar file on the GUI client
workstation.
•
On Linux operating systems: Run the java -jar cmugui.jar command from the directory
where you copied the file on the GUI client workstation.
NOTE: If you launch the GUI through a secure ssh tunnel on a Linux workstation, (secure) appears
on the top bar of the GUI window.
