Sentinel Server Architecture
Sentinel Service (Watchdog)
Watchdog is a Sentinel Process that manages other Sentinel Processes. If a process other than
Watchdog stops, Watchdog will report this and will then restart that process.
If this service is stopped, it will stop all Sentinel processes on that machine. It executes and reports
health of other Sentinel processes. This process is launched by the “Sentinel” Windows Service or
the “sentinel” UNIX service.
