systemctl-service-watchdogs

systemctl service-watchdogs [BOOL]

systemctl service-watchdogs gets or sets the global state of service runtime watchdogs. When enabled, systemd monitors services with WatchdogSec= configured and sends SIGABRT to kill them if they fail to send a keep-alive notification within the timeout period.Disabling watchdogs globally stops systemd from killing and restarting unresponsive services, useful during debugging.When called without an argument, prints the current global watchdog state.

yes

Enable the service watchdog logic globally.

Disable the service watchdog logic globally.

Disabling watchdogs may allow hung services to persist indefinitely. Changes are temporary and reset on reboot. Re-enabling watchdogs with `yes` does not resume monitoring for services whose watchdog already fired while disabled; those services must be restarted.

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.
