Desktop Background Color

You can start several Desktop applications on a specific computer. To tell the difference between the applications and their respective views you can vary the background color of every Desktop. To change the Desktop application background color, set the Desktop property mz.gui.color.space.active.

The value can be any color of the following: blue, green, yellow, orange, red, darkblue, darkgreen, magenta, or darkred. For further information about Desktop properties, see Starting and Managing Desktop Client (4.2).

Dynamic Update

While a real-time workflow is being executed, you can change the value of the following parameters:

  • The Host and Port parameters of the TCP/IP agent

  • The NAS list of the Radius agent

To be able to dynamically update TCP/IP Host and Port parameters, you need to set them to either Default or Per Workflow in the Workflow Properties dialog box. See the figure The Workflow Table Tab in Workflow Table Tab (4.2).

To update, select Dynamic Update from the Edit menu. On the title bar of the monitor dialog-box, the text Dynamic Update followed by a number appears. It represents the number of times that you have updated the workflow configuration while running it, that is since the last time you started it.

Folders

Folders enable the user to categorize configurations, and simplify their maintenance and operation. Folders could for instance be created based on traffic type, decoding for a specific network element, as well as being based on geographic location etc.

Usage Engine includes a system folder named Default. This folder cannot be renamed nor removed.

Configuration Naming

Configuration names within a folder must be unique.

Some named items in the Usage Engine environment are used when constructing file names. To avoid potential conflicts in the file systems, Usage Engine converts the illegal characters when constructing the file names.

The following characters are considered to be legal. Any other character will result in a validation error.

  • a-z

  • A-Z

  • 0-9

  • - (dash)

  • _ (underscore)

Usage Engine has an internal key for every configuration. This key is used to identify the configuration. Renaming a configuration will not change this key. The key is constructed using the system name and the date when the configuration was created. You can view the generated key by selecting the Show Properties option in the right-click menu in the Configuration Navigator, as well as in the Configuration Browser and Configuration Tracer.

Date and Time Format Codes

In various places in Usage Engine, date formats are entered. The following list shows valid date and time format codes that can be combined with any characters that are not in the ranges of 'a'-'z' and 'A'-'Z'. For instance, characters such as ':', '.', ' ', '#' and '@' will appear in the resulting time even if they are not specified within single quotation marks.

The date syntax conforms to the Java class SimpleDateFormat. This section contains a summary only. For a full description see:

MIM

Some agents in a workflow need information from the workflow or other agents in order to operate. For instance, an agent that produces a file might need the source file name and the number of processed UDRs to be used in the outgoing file name. In order to satisfy these requirements,  Usage Engine uses a model called Meta Information Model (MIM) .

Agents may use MIM parameters to publish information during run-time that other agents may need to use. The MIM information is used in various parts of Usage Engine, for instance, when selecting which MIM resources to use in a file name.

Usage Engine uses Java Management Extensions (JMX) to monitor MIM tree attributes in running workflows. For more information, see Workflow Monitor (4.2).

MIM resources for each agent have their values assigned at any time, depending on type. For example, the Disk collection agent publishes the MIM resource Source Filename which is set at Begin Batch. The agent puts the name of the collected file in this resource before it starts collecting the file.

There are in total four types of MIMs:

MIM Type

Description

MIM Type

Description

Batch

Batch MIMs are dynamic values, populated during batch processing. An example of such a value is outbound UDRs.

Global

A global MIM value can be accessed at any time during the execution phase of a workflow. For instance, static values such as Agent Name.

Header

Header MIM values are populated when a batch is received for processing (an agent emits Begin Batch). For example Source Filename (published by the Disk collection agent).

Trailer

Trailer MIM values are populated after a batch is processed (an agent emits End Batch). An example of such a value is Target Filename (published by the Disk forwarding agent).

By default, all agents may publish the following MIM resources depending on their Input/Output data types.

MIM Browser

At places where access to MIM resources is used, the MIM Browser is utilized. You access the MIM Browser from the Analysis or Aggregation agent, by right-clicking in the APL Code area and selecting MIM Assistance....

The browser contains all MIM resources available in the workflow.

The available MIM resources are displayed, ordered in a tree structure. You can choose the MIM resource either by double-clicking the MIM resource, or by selecting it followed by Apply. Cancel dismisses the dialog. You can also search for a specific MIM resource using the filter text box at the top of the MIM Browser.

Locks

Configurations that you edit are locked so that they cannot be modified by other users. When you open a locked configuration, a message box appears with information about the user that has access and can edit it. To edit a locked, or read-only, configuration you can save a copy of it with a different name.

A locked configuration 

Locks are not persistent. If the system is restarted, all locks will be forgotten.

Encryption

A configuration in Usage Engine is persisted using XML and therefore more or less available in a readable form to any user, see Browser (4.2). Some configurations may be sensitive and possibly contain descriptions that are proprietary and must be protected. To protect such configurations, Usage Engine features the ability to encrypt configurations using a passphrase. A configuration is thereby only readable if the passphrase is known by the user. If the passphrase is lost, the configuration should be considered lost as well.

There are configurations that generate information to the system. For example, the Ultra format that renders UDRs. A user can have access to the UDRs without knowing the passphrase for the configuration source, by setting the user group execute permission. A user can also import a format or analysis package which has execute permission configured.

Encrypted configurations retain their encryption and passphrase across export and import. This means that to open a configuration that is imported from another system, you need its passphrase.

The Database profile and some of the agents can use passwords from External References. These can be encrypted, either using the default key, or using a crypto service keystore file. See Using Passwords in External References in External Reference (4.2) for further information.
