WatchingDemon

Overview

WatchingDemon(WaD) performs like a Unix daemon, and monitors registered processes and restarts them in case of a crash. WaD has another process which monitor WaD itself, so works stably for a long time.
WaD can be operated remotely via UDP, and you can extend that functionality with plugins.

Documentation

Application User Manual

Process Monitor

WaD monitors registerd program execution, and analyses its lifecycle. If a process crashed or hanged, WaD kill the process and launch a new process.

To check process health, the following logics are implemented.

  • Process : Whether the process exists.
  • WindowMessage : Whether the GUI is responsive.
  • UDP : Whether UDP packets are being sent.

When the running process (Running) does not respond for a certain period (NotResponding), it is determined that it is not running(Stoped), and WaD terminate the process completely.

You can also set some parameters.

  • Period : Period of time when it is judged to have crashed.
  • Interval : Period from process termination request to restart.

and can set some GUI related parameters.

Packet Trigger

Some functions can be operated remotely via UDP. Other application send a UDP packet which include ID and Parameter, then WaD triggers the function according to them.
You can add triggers with plugins, and can enable/disable them. Some Triggers are implemented in default (Shutodown/Reboot PC, and so on).

If you copy a plugin DLL into “Plugin” folder, WaD automatically analyzes the DLL and gets Triggers from the plugin.

Intelligent Demon

WaD is paired up with another process : Intelligent Demon (InD). WaD and InD monitor each other. If one process crashes, other process terminates crashed process completely, and launches a new proecss.

InD is simple so is hard to crash. Due to such a mechanism, WaD is durable.

Configuration

WaD can be set to start monitoring at launching, and you can also set a listen port number of PacketTrigger.
