<header>Watchdog timeout</header>
<p>Enables the systemd watchdog for services that send watchdog notifications.
This writes <tt>WatchdogSec=</tt>.</p>
<p>Only use this for applications that support systemd watchdog pings, usually
through <tt>sd_notify()</tt>. If the service does not send keep-alive
notifications before the timeout, systemd treats it as failed.</p>
<p>This pairs naturally with <tt>Type=notify</tt> and
<tt>Restart=on-watchdog</tt> or <tt>Restart=on-failure</tt>.</p>
