How to create devices and tasks

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 task

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.

Completion Timeout (in seconds)

Enter the number of seconds the task should wait for a response from the web page before ending the task and returning an error. If this is left blank the default timeout for a task 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 contains the mappings of IP addresses to hostnames.

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

Examples:

192.168.107.246   example.com user.example.com userauth.example.com tools.example.com
192.168.107.246   example.com
192.168.107.246   user.example.com
192.168.107.246   userauth.example.com
