Minimum trace mask
Set the minimum trace mask to get an overview of errors and the most important events
on the installed software drivers. To do so, click ‘Tracing > Minimum Trace Mask’ or click
the corresponding button in the toolbar .
The minimum trace mask influences the settings for all installed adapters, drivers, and
services and changes all trace masks to a minimum level. The following messages are
displayed:
• General Logging: Records information on the startup or termination of the respective
driver.
• Fatal errors: Records fatal errors that prevent the respective driver from being started
or from working.
• Errors: Records general errors that are reported during startup or runtime and that
might be problematic or not.
Basic and extended trace masks for adapters, drivers, and services
If any problems occur during operation of the Diva Server adapter, set the basic level trace
mask to find the cause of a problem in a first step. If the basic level mask does not help
to locate the error, set the extended level trace mask to record further information.
You have to set the basic or extended trace masks for each adapter, service, or driver
separately. To select a trace mask, click ‘Tracing > Predefined Trace Mask’ and select the
required mask.
