Which Appian component is responsible for centralized logging?

The centralized logging in Appian is handled by the Application Server, which is responsible for managing the core functions of the Appian environment, including logging activity related to applications and processes. The Application Server collects and stores logs for various components, including the Process Engine and other features. This central logging capability allows developers and administrators to monitor system performance, diagnose issues, and maintain visibility into application behavior.

The Application Server's logging features facilitate troubleshooting by capturing detailed information about errors, warnings, and system events. This is essential for maintaining the overall health of the Appian environment, as it helps in auditing and ensuring compliance with operational standards.

Other components, while important in their own right, do not focus on centralized logging. The Web Server primarily handles HTTP requests and serves content to clients, the Search Server is responsible for managing search capabilities within the data stored in Appian, and the Process Engine executes business processes but does not provide centralized logging in the same manner as the Application Server. Thus, the Application Server is key in providing a comprehensive view of application activity through its logging functionalities.
