Objet: Re: [pve-devel] systemd notify/watchdog
I don't have found anything... :(
Isn't it possible with perl XS, to create a perl module which use the systemd
c++ class ?
I found a php/hhvm module which is doing something like this
https://github.com/shish/hhvm-sd-notify/blob/master
: [pve-devel] systemd notify/watchdog
OK, so that seems to be something different, so we can us it.
(We need to implemented in perl sd_notify to tell to systemd at regular
interval that the service is running)
Are there really no perl bindings for systemd

Sure, that is no problem. Or can we use the Net:DBUS module somehow?

work without opening /dev/watchdog?
I think it's different than hardware watchdog (in case of system hang).
Here it's more software watchdog, services tell to systemd that they are
running.
(for pvestatd, between each loop for example)

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

If you want, I can upload the jessie packages today - those already include
.service definition files.
Then you can test those features directly ;-)

Unfortunately, a restart does not help in that case?
