GUI: Batch Management of the Dialogs

In the state-of-the-art user interface, certain dialogs are managed alongside each other in batches. These batches are displayed in the header bar of the user interface. Using the mouse, the focus can be switched between these batches. The advantage is that frequently-used dialogs can be kept open and are thus immediately available in the administration. You can open a dialog in a new batch using the middle mouse key.

GUI: Useful Key Combinations

  • CTRL + F1: Administrator guide - CTRL + F9: Activate settings immediately - SHIFT + Tab: Switch through dialog batch - CTRL + SHIFT + F: Search - ESC: Close dialog

GUI: Search for forms

You can search for forms left-hand in the menu. The search result will be displayed in a batch dialog. You will be redirected to the form by klicking the search result.

GUI: Job Notifications

On the system, certain actions are executed in the background. To be able to see the exact status and progress of such background jobs, these are displayed in the administration interface without any delay. The right-upper corner of the Web administration shows whether any jobs are currently active in the background. Several jobs may be started simultaneously. The progress of a job is indicated in percent. Errors are highlighted in color.

GUI: System Information

Collax Server offer extensive possibilities to analyze the entire system. For this purpose, a lot of information is provided: from product information to the graphical presentation of the system load to detailed statistics. Product Information The left-hand side of the menu features some important basic information about the product, the current version, and the license status. Individual lines can be selected and copied with the mouse pointer. Current System Load The System Load section presents a graphical display of the current system load. More comprehensive and detailed statistical graphs can be accessed with a click. Statistics The statistical graphs show the CPU, RAM, hard disk, and network traffic load in the form of continuous performance curves.

GUI: Smart dialog guidance assists

During the configuration of the system, the smart dialog guidance assists you in certain configuration tasks. All needed parameters are queried under consideration of the context, and feedback is provided concerning any additional settings or actions.

You can filter search insied tables now.

GUI: Current system time

Collax Server offer extensive possibilities to analyze the entire system. The left-hand side of the menu features some important basic information about the product. This field displays the uptime since the last system boot and the average system load of the last minute, the last 5 minutes, and the last 15 minutes. From now on this field also displays the current system time in the local time zone.

CVE-2014-7186

CVE-2014-7187

V-Cube+: UPS-Service

In the dialog UPS-Service, the access permission can be set for the UPS administration service for networks. Access to the UPS service is useful if a UPS is connected to the local server and information on power failures is to be forwarded to other nodes in the network. Due to an error the permission could be removed under certain circumstances after an configuration activation. This lead to an error message User-agent timeout in the Web Administration interface. With this update this is fixed and a patch is being implemented.

Misc: Nagios Swap-Check

An erroneous nagios configuration was written and produced wrong warnings, when the server had less swap than RAM.
