Hi there,
ROS 6.43 added *) watchdog - added "ping-timeout" setting;
But this is undocumented. Please add documentation for this new setting explaining exactly how it works.
From what i know there's more to it. It doesn't restart after 1 failed ping, but requires a certain amount of failed pings within a time interval. This should be properly documented in the documentation and is not currently documented. See https://wiki.mikrotik.com/wiki/Manual:System/WatchdogAs i understand it goes with Ping Start After Boot, so when Watchdog happen it will be ping time out for 60s and then process will start over
It would not be correct for me to speculate about how a feature works. It should be documented.did you make a test? what your result say?
Thank you for the update.Somehow we have missed to update wiki Watchdog page, now this feature is documented.

It's still a little bit clunky.watch-address (IP; Default: none) The system will reboot, in case 6 sequential pings to the given IP address will fail. If set to none this feature is disabled. By default router will reboot every 6 minutes if watch-address is set and not reachable.
no-ping-delay (time; Default: 5m) Specifies how long will it wait before trying to reach the watch-address.
ping-timeout (time; Default: 60s) Specifies the time interval in which the device will be pinged 6 times (after "no-ping-delay").
That seems quite plausible. But I really urge Mikrotik to make it absolutely clear in the documentation as this is a critical feature for routers and if this feature misbehaves or is misunderstood based on insufficient documentation it can cause unnecessary downtime.I think it is like this: after boot, the router first waits for no-ping-delay before doing anything. To give other devices time to initialize and make a connection.
Then, it starts pinging at an interval of ping-timeout/6. So, one ping every 10 seconds for the default ping-timeout of 60s.
When no pings get returned for the ping-timeout interval (i.e. 6 consecutive missing ping replies) the router reboots.
