<
logfile
> is the name of the log file to be created. If you installed the client on a different drive and
directory, make the appropriate substitutions. Optionally, piping output to “tee,” if you have it available,
allows you to see the logs on the console as well as logging the data into the file.
Be sure to use different log file names if you are running multiple clients on the same machine.
Using the Browser-based Client (Windows Only)
NOTE
After a problem occurs, prior to pointing the browser to the EPICenter server, it is recommended that you
clear all browser cache information, including disk cache, and close and re-open the browser.
If you are using the browser-based client, please try to duplicate the problem with the Java Console
enabled in Internet Explorer. Look at the Java Console window and copy/paste (using [Ctrl]+C and
[Ctrl]+V on Windows 2000/XP) the contents into a text file. If a problem occurs, Extreme Networks
customer support may require the Java Console output.
In addition, you can run the client in a debug mode in the browser:
1
Start the client with the URL
http://<host>:<port>/everest/debug
.
2 After you enter your login information, but before the main EPICenter page is displayed, a page with
debug settings is displayed.
3
Select
Info
for “Client Debug Level.”
4 Click Submit Query .
This enables more detailed information to be logged.
Enable the Java Console
To facilitate problem diagnosis, you can attempt to duplicate the problem with the Java Console enabled.
To enable the Java Console, do the following:
1 From the Windows Start menu, select Programs , then Java Plug-in Control Panel and launch the
Control Panel.
2 On the Basic page, click the Show Java Console check box.
3 Click Apply.
The next time you launch the EPICenter client, the Java Console will start automatically.
NOTE
Running with the Java Console displayed may reduce the performance of the EPICenter client.
There is limited space for Java Console messages; once the console log file is filled, no more messages will
be recorded. If you are trying to duplicate a problem, clear the Java Console log file periodically by clicking
the
Clear button at the bottom of the window.
You can close the Java Console by clicking the Close button at the bottom of the window. However, once
it is closed, it can only be restarted by closing and restarting the browser.
