title: Nagios: config ping times
body: <p>I am using nagios ver. 4.0.8 . 
  I want to set interval between ping times is 10 seconds like below:</p>
  
  <pre><code>define command{
  command_name    check-host-alive
  command_line    $USER1$/check_ping -t 10 -H $HOSTADDRESS$ -w 3000.0,80% -c 5000.0,100% -p 5
  }
  </code></pre>
  
  <p>But not exactly (about 90 seconds). Can you help me? 
  Thanks</p>
