Monitoring System Log Messages with the J-Web Event Viewer

To monitor errors and events that occur on the device, select Monitor > Events and Alarms > View Events in the J-Web user interface.

Note: After you make changes to the configuration in this window, you must commit the changes immediately for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes (J-Web Procedure) for details about all commit options.

Note: When you use an HTTPS connection in the Microsoft Internet Explorer browser to save a report from this page in the J-Web interface, the error message "Internet Explorer was not able to open the Internet site" is displayed. This problem occurs because the Cache-Control: no cache HTTP header is added on the server side and Internet Explorer does not allow you to download the encrypted file with the Cache-Control: no cache HTTP header set in the response from the server.

As a workaround, refer to Microsoft Knowledge Base article 323308, which is available at this URL: http://support.microsoft.com/kb/323308. Also, you can alternatively use HTTP in the Internet Explorer browser or use HTTPS in the Mozilla Firefox browser to save a file from this page.

The View Events page displays the following information about each event:

Process—System process that generated the error or event.
Severity— A severity level indicates how seriously the triggering event affects routing platform functions. Only messages from the facility that are rated at that level or higher are logged. Possible severities and their corresponding color code are:
- Debug/Info/Notice (Green)—Indicates conditions that are not errors but are of interest or might warrant special handling.
- Warning (Yellow)—Indicates conditions that warrant monitoring.
- Error (Blue)—Indicates standard error conditions that generally have less serious consequences than errors in the emergency, alert, and critical levels.
- Critical (Pink)—Indicates critical conditions, such as hard drive errors.
- Alert (Orange)—Indicates conditions that require immediate correction, such as a corrupted system database.
- Emergency (Red)—Indicates system panic or other conditions that cause the routing platform to stop functioning.
Event ID—Unique ID of the error or event. The prefix on each code identifies the generating software process. The rest of the code indicates the specific event or error.
Event Description—Displays a more detailed explanation of the message.
Time—Time that the error or event occurred.
