By default, the Client logging level is set in a special utility.

You can change the logging level of the Client and restart it for changes to take effect. The next time the Client is started, the logging level will correspond to the new settings in the logging management utility (see Log Management Utility).

To change the logging level of the Client, do as follows:

1. Select  Settings -> Options -> Logging management (1-2).
2. Select the desired logging level (3). Levels are described in more detail here Configuring Logging Levels. 
3. Click Apply.

You can also delete all the Client logs. Please follow the steps below:

1. Click Clear client logs (4).
2. Click Apply.
