The NoMachine Web Companion is a Java applet which displays information in the browser's Java console on the end-user's machine.

To increase the debug log level, edit:

- the nxapplet.html file

- and since v. 5.1.22, also the nxapplet.jnlp file.

These files are placed in the Document Root of the Web Server serving the Web Companion.

Look for the 'loglevel' parameter and set it to the appropriate value. For example:

<param name="loglevel" value="3" />

Accepted values are:

Log level: 0 -> PANIC, display only fatal errors.
Log level: 1 -> WARNING, display errors and warnings.
Log level: 2 -> TEST, display errors, warnings and information about main operations executed by the applet.
Log level: 3 -> DEBUG, display errors, warnings and specific information about operations executed by the applet.

Other values are not accepted and can cause exceptions (e.g. ArrayIndexOutOfBoundsException).
