PlatformServiceContainer actions

The PlatformServices Container also provides three (right-click) actions, as shown below.

These actions are described as follows:

Send Thread Dump to Console
Causes that host’s platform daemon to have the station send a VM thread dump to its standard output (console), equivalent to the “Dump Threads” command in the platform Application Director view. Typically used only during troubleshooting.

NOTE: Apart from Application Director (platform access) to view station output, you can also view a “snapshot” of station output in a browser. Do this via the “stdout” link in the spy utility, at URL http://<hostIP>/ord?spy:/stdout
Request Garbage Collection
Causes the JVM running the station to perform garbage collection. This results in a “best effort” towards releasing unused objects and making more memory available on the “heap”. Note that current heap and memory statistics for any running station are available on the ResourceManager view of the station component.
Restart Station
Produces a popup confirmation dialog. Applies directly to any Niagara 4 station, whether running on a JACE controller or a Windows platform. It is equivalent to issuing a “Restart” command from the platform Application Director view (station is saved on its host, then restarted). Note that unlike in NiagaraAX, this does not result in a reboot of a JACE controller.

NOTE: Also, most child services under the PlatformServices Container have an available “Poll” action, which refreshes their property values. See “Platform service types” for a listing of possible child services.
