Monitor setting in new a feature in Trident which allows the user to only log workflow/activity events to a file. These workflow/activity events are raised as part of the execution of a workflow. These events are logged in the predefined way and cannot be
customized based on the custom activities.
Coming back to your question <<I am wondering whether there is a way to let activities use Trident logging system in this version?
No. The latest version of the Trident also does not allow to use the Trident Logging mechanism in custom activities.
However, Tridentv1.2.1 being released to Open source community, it would be great if you can go ahead and add the functionality which is useful.
For any further help/concerns please feel free to start a new discussion thread.
