The Telnet monitor checks for a Telnet server on port 23. If no telnet service responds on this port, then the service is considered Down.

为监控器提供唯一名称和描述，然后配置以下信息：

  • Timeout. Enter the length of time attempts to connect to the selected device. When the specified time is exceeded without connecting, a timeout occurs and stops trying to connect to the server. This is considered a failed connection.
  • Use in rescan. Enable this option to have the monitor appear in Device Properties. If enabled, clicking Rescan Device from the device management actions menu within the Device Properties interface adds the monitor to the selected device if the applicable protocol or service is active on that device.
