Someone correct me if I am wrong.
Watch Dog – Mini Watch Dogs.
Many company’s like lets say Blizzard Entertainment the makes of World of Warcraft. (this also applies to any type server) Have what we call watch dog running. This is a program that runs at the hardware level of the system. This program runs some diagnostics every so often to see if the OS is running properly and the system is responding. When the OS freezes or the system stops responding for any reason, watch dog figures this out and initiates a reboot at the hardware level. This in turn gets the Machine back up and running. (saving time, by not having to have someone go and reboot it manually) Which means getting people back to their game if something happes. For Dish Network Subs this means getting your Unit Back up and running and back to watching the programming we pay for.
My unit has a problem with OTA so it tends to reboot a lot more than it needs to Hence my mini watch dogs are at 15.
Kernel Panic.
This is a crash or error at the core of Software.
Mac Users- Ever get that screen that is shaded dark with a big square in the middle, with the picture of a power button that reads. Your Machine needs to be rebooted. Please hold down the power button for 3 seconds. This is a kernel panic, something happened that caused the machine to just halt.
Windows Users- Ever get a blue screen with righting that says to prevent damage to your system. The system has been halted or has stopped (something like this). That is a kernel panic.
If your kernel panic is at 0 This is a good thing.
AC PWR/HW WS CNT.
This I believe is how many times the received has lost power or been unplugged.
I have had my 622 2 months and have only unplugged it 2 times. Mine is at 2.
Boot Recoveries:
Boot ups gone wrong. (just and educated guess.)
The rest i dont know.
