[pve-devel] systemd notify/watchdog

[Alexandre DERUMIER]

systemd have a watchdog feature 

http://man7.org/linux/man-pages/man3/sd_watchdog_enabled.3.html

which could be great for some services, like pvestatd. (which sometimes can freeze which slow/bad storage stats)


The idea is that the application need to send notifify at regular interval to systemd,

http://www.freedesktop.org/software/systemd/man/sd_notify.html
https://lists.debian.org/debian-ctte/2013/12/msg00230.html



If systemd don't receive the notify after some time, it can restart the service.
