How It Works
Telnet port availability monitoring tests connectivity to a web server through a certain TCP port.
Configuring a Request
Enter the server address to be monitored. This could be an URL or IP address.
Enter a port number of the service you wish to check.
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.
To specify the mapping, enter the IP address and the hostname in the corresponding fields.
