How to Сreate Devices and Targets
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.
Server domain address or IP address.
Enter the port number of the UDP service to test.
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.
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. IPv6 and IPv4 DNS resolution is supported.
To specify the mapping, enter the IP address and the hostname in the corresponding fields.
