How do you set a new port range in Dynatrace OneAgent?

To set a new port range in Dynatrace OneAgent, the command that is used is the one that specifies the watchdog port range, which is crucial for the operation of Dynatrace. The correct command includes the syntax to set the range, which is formatted as --set-watchdog-portrange=lower:upper, effectively defining the minimum and maximum ports to be used by the watchdog processes.

This command allows the OneAgent to listen on the specified range, ensuring that it can interact appropriately with various components within the monitored environment. The specified port range must be within the allowed limits for the operating system and should not conflict with other services. By using the correct command to set the port range, you ensure that Dynatrace can maintain effective monitoring and operations.

The other choices do not correspond to valid commands for modifying the watchdog port range in the context of Dynatrace OneAgent. Therefore, it's essential to utilize the specific command that clearly defines the action of setting a port range, which is precisely what the correct option does.
