K-Bench Benchmarking and Server Side Metrics

[ThunderStorm710]

Good evening
First of all congratulations on the awesome tool.
I am a master's student in Computer Engineering at the University of Coimbra and, together with another colleague and supervisores, we are carrying out a scientific paper in which we are using K-Bench for benchmarking. We ran different tests (cp_heavy_12client, cp_heavy_8client, cp_light_4client and cp_light_1client) and with neither of those tests we managed to retrieve information on the server side metrics such as Image pulling latency. Is this supposed to happen or should we use another flag other than -benchconfig so as to run the tests?
Thank you for your attention.
