Log-Viewer

Log-Viewer is a tool for viewing and filtering of Valuemation log files. If enabled, Log-Viewer can be opened from the Settings menu in the Rich Client main menu bar.

The Log-Viewer window provides the following elements:

Connection Types:

One of 3 connection types can be selected:

• Local file

  This is the default type. The logfile is stored on the user's local machine. The location of the file is set either as absolute or relative path in the 'File' field.

• Through RMI

  When the Remote Method Invocation type is selected, two extra parameters are listed with file name. These are Server Host Name and Server Port. This connection provides means for invoking the methods of remote Java objects.

  Note: As this connection requires some other advanced settings of Valuemation, it is strongly recommended to contact USU support personnel to start using it.

• Through HTTP

  Http protocol is used to access the log file at the given url.

Filter Options:

It may be difficult to locate a specific message in a large log file. The Filter Options section can be used to filter the selection via the following attributes:

• Maximum Log Level

  Messages are logged at different severity log levels. 'Maximum Log Level' makes it possible to filter out messages with severity lower than the specified number.

• Select Module

  Only messages logged by the specified logging module will be displayed.

• From Date
• To Date

  Only messages logged within the specified time interval will be displayed.

Click the 'Apply' button in the upper right-hand corner of the window to apply the selected 'Connection Type' and 'Filter Options' on the list of log messages displayed in the bottom section of the window.

The list contains the following columns:

• Level

  The log level of the message

• Error Text

  Actual text of the log message

• Logging Module

  Logging Module which issued the message

• Date

  Date and time (timestamp) when the message was logged

Related buttons:

• Message Details

  For long messages, the button displays the whole in a separate window.

• Delete Log-File

  Clears all the messages and resets the log.
