title: Centreon/Nagios optional arguments in commands
body: <p>Is there a way to put optional arguments in <strong>centreon/nagios</strong></p>
  
  <p>A simple example. In Centreon:</p>
  
  <pre><code>$USER1$/check_http -H $ARG1$ -p $ARG2$ -w $ARG3$
  </code></pre>
  
  <p>Host <strong>(-H)</strong> and port <strong>(-p)</strong> arguments as <em><strong>required</strong></em> and warning argument <strong>(-w)</strong> set it as <em><strong>optional</strong></em></p>
