There's no mechanism to get dumpcap to periodically produce the report.
On BSD-derived OSes, such as macOS and the *BSDs, you can send it the SIGINFO signal to get the report printed.
If you're running it from a terminal, and the stty -a command prints
cchars: ...
...
... status = ^T;
...
(the only thing that's relevant is status = ^T;; I've omitted the rest of the stuff it prints), you can type ^T while dumpcap is running in the foreground and it should print that information. If something such as status = <undef> is printed, do stty status '^t' first.
If you're not running it from a terminal or it's in the background, the kill command can be used to send the signal.
If you're on any other OS, you're out of luck.
