This currently isn't exported by systemd, and there's even no log message at debug level. I guess this could be exposed, but I don't think it'd be very useful. If the watchdog ping works, most people don't need to look at it. If it doesn't, the machine should reboot...
Yes. Maybe I should be more clear in my goal: enabling the systemd option to ping the watchdog doesn't have any visible effects until the system hangs. I wanted to see an "effect" without resorting to "echo c > /proc/sysrq-trigger".
If this is just for debugging, you can do something like sudo strace -e ioctl -p 1 and look for WDIOC_KEEPALIVE.
Yes, this is exactly what I was looking for! As far as I can see adding "-r" to strace prints nice relative times that correspond to the "RuntimeWatchdogSec" value.
Thank you very much! Kind regards, Wiktor -- https://metacode.biz/@wiktor _______________________________________________ systemd-devel mailing list systemd-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/systemd-devel
