Overrides:

requiresWantedPort in class AbstractService

Returns:

'true' always

getPortCount

public int getPortCount()

Description copied from interface: NetworkPortRequestor

Returns the number of ports needed by this service. User-defined ports for container http servers should not be counted, as those ports are required to be outside Vespa's port range.

Returns:

the number of ports needed by the logserver.
