Introducing EAS Cluster Management
and New Convenience
in the Lutris Management Console
By Chip Bancroft, Lutris Technologies Engineer
The best part of working on the second version of a software product
is that you get to tune it, incorporate feedback from the first version
and add those features that you wished you'd had time for with version
1.0. So, this article is about the improvements made to LMC to make it
more effective and comprehensive in its network awareness as well as simply
make it a smoother experience in general.
In general, there are three categories of improvements, ranging from
start-up conveniences to more profound network monitoring and management.
- New convenience server preferences
- Streamlined login/connection
- Cluster view and management
Server preferences
Menu select "Edit | Preferences..." and open the Server tab.
Click on the image to the right to see a large version. There are a number
of handy preferences.
- Automatically discover servers when LMC starts (default)
- Automatically start local server when LMC starts
- Automatically stop local server when LMC stops
- Specify a default username/password that populates the login dialog
- Indicate your preference for long or short host names.
- Automatically login to local server using specified username/password
- Automatically open a log channel view into the EAS log after login
You can now undeploy multiple components at a time by <ctrl><click>
to select multiple components. Then press the "Undeploy" button.
Cluster View
There is an new Cluster view capability that gives you the ability to
operate on multiple servers at one time by either selecting the cluster
you are in or by <ctrl><click>ing to select multiple servers.
You can "Refresh the MBean tree for all" or "Login to all",
"Logoff from all", and "Shutdown all". During Login,
a login dialog prompts for a username and password that are used to attempt
to login to all selected servers.
Other Features and Behaviors
Windows Desktop Interaction
On Windows, you can drag and drop from the desktop/folder deployable
objects. Try selecting multiple apps and drop them on a selected cluster/hosts
and they will all get deployed to all servers in the cluster or all servers
selected.
MBeans are no longer automatically fetched when
you login to a server.
This enables you to login and open EAS log views on multiple servers
without having to fetch all of their MBeans (time/resource saver). Using
the new server preference, and the ability to operate on multiple servers,
you can login into multiple servers and have their EAS log view automatically
opened.
MBean Convenience
Save frequently used MBeans in the Toolbox. Double clicking on them will
display a login dialog if necessary and open the MBean without having
to fetch all the MBeans in the tree. The server that the MBean is associated
with must be discovered before attempting to open the MBean.
Custom Logs of Cluster servers
The image to the right shows one of the extensive logging features, making
it possible to define and then monitor custom logs the local or remote
EAS server or servers.
