UDP Device

How to Create Devices and Targets

• • Creating a Device
  • Adding Several Targets within a Single Device

How It Works

If a web application provides voice or video transfer over the Internet over the User Datagram Protocol (UDP), UDP monitoring is useful to make sure a UDP server is reachable. Dotcom-Monitor can test UDP server availability by sending packets to a specified port and receiving a response.

Creating a Target

Once you have created a device and are adding or editing a UDP task, you will be prompted to adjust the following settings.

Hostname

Server domain address or IP address.

Port

Enter the port number of the UDP  service to test.

Time Validation Threshold (in seconds)

Enter the number of seconds the system should wait for a response from the target resource before returning an error. If this is left blank the default timeout is 120 seconds.

DNS Options

The DNS Options feature allows users to choose how domain name server (DNS) requests are conducted during a monitoring task.

To specify the mode of resolving hostnames, in the DNS Resolve Mode section, select one of the available modes. For more details on the feature configuration, see DNS Mode Options.

The Custom DNS Hosts section allows to set up the mapping of IP addresses to hostnames. IPv6 and IPv4 DNS resolution is supported.

To specify the mapping, enter the IP address and the hostname in the corresponding fields.
