Each Build Project contains a Project Trigger Log which provides a history of trigger activity. Log entries are added when builds are triggered, or when triggers encounter errors.
To view the Project Trigger Log, navigate to the Build History page for the project, and then click on the Project Trigger Log tab.
Example Project Trigger Log
Project logs are persisted to disk and can be found in C:\ProgramData\VSoft\FBServer7\Logging\Projects
