I have an issue with Netwatch on 7.5 release and also v7.6beta4 on one RB5009. For some reason, none of the execution stats are updating.
add disabled=no timeout=5s type=icmp host=208.67.222.222 interval=15s
Nothing special, one a hex this updates every 15s with the execution counter going up, on a rb5009 with a very similar overall config, it does not increment.
That said it seems to detect actual up/down events, just none of the stats update via Webfig, Winbox nor “print stats”.
