$ systemctl service-watchdogs yes

$ systemctl service-watchdogs no

systemctl service-watchdogs [yes|no]

systemctl service-watchdogs gets or sets the global state of service runtime watchdogs. When enabled, systemd monitors services with WatchdogSec= configured and restarts them if they fail to signal liveness within the timeout period.
Disabling watchdogs globally stops systemd from killing and restarting unresponsive services, useful during debugging.

Disabling watchdogs may allow hung services to persist indefinitely. Changes are temporary and reset on reboot. Individual service watchdog settings still apply when re-enabled.

The service-watchdogs subcommand provides a global kill switch for the watchdog mechanism, useful when debugging services that would otherwise be restarted before investigation completes.
