Log Viewer and Settings
The Log Viewer & Settings utility is available for a business administrator from the Business Administration Utilities page under Site 
.
.Clicking the Log Viewer and Settings, displays a page that has links to view and configure logs. These links provide a convenient way to get information about how your system is running from your browser instead of bringing up another program.
The following list describes how to use each of the links on the Log Viewer and Settings page:
• Clicking the Log Levels link presents a page from which you can display or set log levels for server manager, method server, or servlet engine loggers for current server processes. First select one or more processes and then browse for the logger.
• Clicking the Log Comment link presents a page where you can enter a comment that is then stored in server manager and method server logs. If your environment is set up as a cluster, the logs include logs stored on all nodes in a cluster.
Use this link to add log entries that can do things like demarcating the start and end of a load test or indicating when some configuration fix (such as a file permission fix) was made that did not require a server restart.
Essentially, this link allows an administrator to add a comment to the server logs. Consider adding comments when an important, known state change has occurred that the system itself would not detect and the addition of a comment in the logs could ease later troubleshooting or analysis.
• Clicking the Log File Viewer link presents a page from which you can search, list, and view server log files.
For details, see Using the Log File Viewer Page.
• Clicking the Persisted Log Events link presents a page from which you can browse recently persisted log events and view event details. By default, the Minimum Severity Level is set to WARN and the age of the listed events is from the last six hours. The level selected is the lowest level of events returned; therefore selecting WARN returns warning, error, and fatal events. Selecting OFF returns only log events whose level is OFF, which normally do not exist.
For details, see Using the Persisted Log Events Page .
• •Clicking the Log Event Histogram link presents a page from which you can decide on the age of the log events to display and select the Minimum Severity Level to include. Available error levels are listed in the order of severity, lowest (OFF) to highest (All). For example, using the default (WARN) level includes log events associated with the FATAL, ERROR, and WARN levels.
Clicking OK presents a histogram in tabular form that shows the list of events by logger name, level, and count.
