Enabling integration logging for the system
You enable integration logging for the system on the Statistics page in NexJ System Admin Console and specify the amount of time that logs are stored before being deleted.
For logs to be generated, you must enable integration logging for at least one channel in addition to the system. For information about enabling integration logging for individual channels, see Enabling integration logging for a channel.
One point that is not clear here is that enabling integration logging "for the system" doesn't actually result in any logs being generated by itself. Logs are only generated when integration logging has been enabled for the system and at least one channel. There is a directive line at the bottom starting with "Next, ..."
To enable integration logging for the system:
Next, enable integration logging for individual channels.
