[en] Enable Control Center and Web Printing tracing

[en] Problem

[en] You face problems with Control Center (on-premises installation) or Web Printing, which you can't resolve with the standard methods. Our development team can identify and resolve such issues by analyzing trace log files.

[en] Solution

[en] Tracing is not enabled by default. You can enable tracing for Control Center and Web Printing events by editing Control Center configuration files.

Nota

[en] Tracing can slow down your Control Center and Web Printing. Trace log files take disc space which can be critical if tracing is running for a longer time. After you reproduce the issue, disable the tracing.
