When systemd is configured via the unit file to use a watchdog and watchdog support is activated -in the audiomanager, the audiomanager will reset the watchdog via the mainloop in the given interval to prevent systemd from restarting the audiomanager.\n -If the audiomanager is stuck for whatever reason, systemd will not get this update and restart the audiomanager. - - -\section configwatch Watchdog configuration -By default, the watchdog is enabled in the audiomanager, you can disable the watchdog functionality by setting the cmake build option "WITH_SYSTEMD_WATCHDOG" to -OFF, either by modifying the cmake cache with ccache or by passing -DWITH_SYSTEMD_WATCHDOG=OFF to cmake.\n -The interval for checking the watchdog can be set in the unitfile of systemd by setting "WatchdogSec". The other settings need to be done as well: -\code -Restart=always -WatchdogSec=2 -NotifyAccess=main -\endcode -The intervall for pinging systemd is set to the half of "WatchdogSec". - -\section winteg Integration with systemd -The audiomanager will use the library proviced by "libsystemd-daemon" if it is available on the system. If this library is not available, the files sd-daemon.c and sd-daemon.h -that are provided with the audiomanager and released under MIT licence by Lennard Poettering will be used to connect to systemd. - -more information can be found here: am::CAmWatchdog and sd-daemon.h . - - - */ |
