Event log and process control
Your automation software might consist out of several processes running in the background. These processes might want to print event log messages to a central instance. The user might want to view these messages either online or review old messages.
Also you might want to have a means to view and control those background processes. And you might want to have some kind of watchdog that automatically restarts processes when they are missing for some reason.
The above can be done with pcontrol which is a pvserver under directory pvbaddon/pcontrol in the pvbaddon package.
