Watchdog¶
Pantavisor also offers some configurable convenience to set up and ping the Linux Kernel watchdog.
Mode¶
The watchdog mode will determine when the watchdog is pinged by Pantavisor.
Disabled¶
In this mode, Pantavisor will never ping the watchdog.
Shutdown¶
This is the default mode. Pantavisor will start pinging the watchdog when a reboot or poweroff order is issued. This way, we make sure the device reboots in a shutdown freeze event.
Startup¶
This mode combines Pantavisor pinging the watchdog during initialization and shutdown. As the watchdog is activated with a ping, it is expected that a container will take that role during the device regular operation.
Always¶
In this mode, Pantavisor will ping the watchdog during all the device operation.
