Process Manager

A valuable tool in almost every developer's toolkit is a system monitor. A system monitor shows a list of running processes, how much memory and CPU resources are consumed by each process, and has the ability to force processes to end. Task Manager on Windows and Activity Monitor on macOS are two examples of a system monitor.

OpenFin Process Manager is the system monitor for OpenFin processes.

  1. A list of all OpenFin platforms and OpenFin legacy applications.
  2. An expandable list of all OpenFin windows associated with that platform or application.

List of OpenFin platforms and OpenFin legacy applications

Process Manager displays a constantly updated list of platform and legacy application processes. Each platform application or legacy application in the list shows the OpenFin Runtime version, CPU and memory used, and the program ID.

When the mouse passes over a row in the list, additional information and controls are displayed.

If the row displays an OpenFin Platform or Platform application, the word "Platform" appears to the right of the process name. If the row displays an OpenFin legacy application, the word "Application" appears to the right of the process name.

Additional control buttons appear while the mouse is over the row.
