After following the steps in the tutorial i expected that the Protocol Hierarchical Statistics would have been extended with the stats details. This is not the case however. Although with tshark i can see that the details are being collected. Is there a way to expand the phs to show the details?

tshark -r /home/kurt/wireshark/foo_test.pcap -z foo,tree -z io,phs
OOPS: dissector table "sctp.ppi" doesn't exist
Protocol being registered is "Datagram Transport Layer Security"
