+=================================

+Salt Stack will automatically detect the necessary kernel module which needs to be loaded (ex. hpwdt, iTCO_wdt).
+If the hardware model is not predefined in map.jinja the default watchdog driver is used: softdog
+You may specify the kernel parameters if needed:
+
+.. code-block:: yaml
+
+    watchdog:
+      server:
+        admin: root
+        enabled: true
+        interval: 1
+        log_dir: /var/log/watchdog
+        realtime: yes
+        timeout: 60

-            parameter: value

+INFO: extra formula [salt-formula-linux](https://github.com/salt-formulas/salt-formula-linux) required.
+
+In that case, apply command should also care about linux state. For example:
+
+
+.. code-block:: bash
+
+  salt "kvm0*" -l debug state.apply watchdog.server,linux.system.kernel -l debug
