How to create devices and tasks
Telnet Port Availability task
The Telnet port availability task allows you to send a request to a specific port on a server to make sure that you receive a response.
Creating a task
Once you have created a device and are adding or editing a Telnet Port Availability task, you will be prompted to adjust the following settings.
Enter the server address to be monitored. This could be the URL or the IP address.
Enter the port number of the service you wish to check.
Completion Timeout (in seconds)
Enter the number of seconds the task should wait for a response from the web page before aborting 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 host name in the corresponding fields.
