Admon Main Menu


The menu is a tree-like view on the left hand side and the associated windows will open on double-click.
The following sections will give a short overview of the different items.


Metadata Nodes


The menu item "Metadata Nodes" contains an overview page, as well as a dedicated page for each metadata node in the system.
The overview shows basic information, the status of all nodes and the total number of metadata requests in the system.
The page for a specific metadata node shows some general information on the node itself, the status of the node and the number of work requests to this node.


Storage Nodes


Like the meta nodes menu, the menu item "Storage Nodes" also consists of an overview page, as well as a dedicated page for each storage node in the system.
Values which can be retrieved on these pages include the general status information, as well as disk space usage and data throughput.
For disk performance, four values are displayed. While the read and write graphs are very exact (measured every second), they are also very erratic. The averaged graphs are better suited to identify a tendency. These graphs are always an average of the last 30 values. You can easily hide each throughput line by disabling the appropriate checkbox under the graphic.

Note that only the 10 min history view is based on the exact one second interval. The other history views are based on more coarse-grained (averaged) values.


Client statistics


The pages contains the client statistics for metadata operations (create, stat, ...) or the clients statistics for the storage operations (read, write, ...).


User statistics


The pages contains the user statistics for metadata operations (create, stat, ...) or the user statistics for the storage operations (read, write, ...).

Management


The management pages contain elements for administrative tasks. The page "Known Problems" is designed as a quick overview of the system's health. All problems related to the status of the nodes and their interconnection are listed here. The "Start/Stop Daemon" page allows start or stop all daemons and clients. The item "Log Files" opens a window which shows the log files of all daemons and clients.


FS Operations


The menu item "FS Operations"->"Stripe Settings" allows you to view and change the striping information in your file system. In BeeGFS, it is possible to define the chunk-size of data that will be written, as well as the number of storage targets, over which one file will typically be distributed. The corresponding information can be retrieved on this page. Furthermore, if you logged in with administrative privileges, the system will allow you to change these settings for each directory in the file system.

With the file browser you can browse through the global BeeGFS and retrieve information on the stored files. Please note, that although you are able to see directories and files, you will not be able to view the content.


Installation

The management pages contain elements for automation and simplification of the installation/uninstallation tasks. Please refer to the BeeGFS installation guide for a detailed description. Also the installation log file is available in this menu.



Admon Menu Bar


The menu bar contains options which are not required for the installation and the day by day administration.


Admon


The menu item "Change Settings" contains the configuration options of the GUI. Also the logout option and the close option for the GUI.


Administration


The options inside the menu item "User Settings" allow you to change the login passwords and to disable the password for the Information user. The effect of the latter is that users can view the web-frontend without being asked for a password. (The administrative account is not affected by this setting).

The menu item "Mail Settings" lets you define some values for e-Mail notifications by the software. If configured accordingly, an administrator can receive an e-Mail whenever a node in the system appears to be down.
These pages are only accessible by the user "Administrator".
