IM Relationship Resolution Information Center, Version 4.2

Visualizer log files

The Visualizer has two types of log files available to assist users in troubleshooting Visualizer problems or messages: a local log file for each Visualizer client, and log files for the InfoSphere Application Server that hosts the Visualizer.

Visualizer client logging

You can configure the Visualizer to log errors, warnings, and informational messages that occur on your local Visualizer client. Each workstation contains one Visualizer client, so you can determine whether or not to log Visualizer messages by workstation.

By default, Visualizer client logging is turned off. You turn Visualizer logging on or off and select logging settings in the Configure Screen Preferences window on the Log Settings tab.

You determine the directory location of the Visualizer client log file when you turn Visualizer client logging on, by entering the name of the directory or by browsing to an existing directory. The default name of Visualizer client log files is visualizer.log. This file is a text file, that can be viewed using any text editor.

Messages append to the existing log file, until the maximum file size is reached. The maximum size for a Visualizer client log is 1 megabyte.
  • If the log file reaches the maximum file size, the system creates another Visualizer client log file in the configured directory location and begins logging messages to that log file.
  • Once the second log file reaches the maximum size limit, the system then automatically rotates message logging to the first log file, until it is full.

This automatic log file rotation continues each time the current log file reaches its file size limit. As the system rotates log files, it writes over the previous messages in that log file.

InfoSphere Application Service logging

The Visualizer relies on the InfoSphere Application Server to communicate with and connect to IBM Relationship Resolution. Web services events are logged in the application server log files, along with the Configuration Console and Web services events, which also rely on the InfoSphere Application Server.

The application server contains two primary log files that can be used to troubleshoot problems:
  • System messages, which are logged in the file named was_ee_SystemOut.log
  • System error messages, which are logged in the file named was_ee_SystemErr.log

These log files are located in the following directory:

installation_directory/logs/was_ee

InfoSphere Application Server log files are configured by a system administrator on the application server or through the IBM Relationship Resolution configuration utility.
