Replacement for KTrafficAnalyzer?

Hello, I was using KTrafficAnalyzer https://sourceforge.net/projects/ktrafficanalyze/  for quite a long time to get simple information about traffic. Now this is quite old and now it is missing as official package in OpenSuSE Leap 15.2 . Which official rpm can I take as replacement? It should be as simple as KTrafficAnalyzer, no sniffer, no Nagios, no rrdtool and alike, also no commandline tool. If I have to compile from source it is also ok (KTrafficAnalyzer is compilable but then fails to run). Thanks in advance Markus
