Hi, You should use use option --sample-rate with '@' as you want nprobe to rescale statistics from sampled packets but not to sample itself. In your case this should work:
--sample-rate @10:1 See the help: [--sample-rate|-S] <pkt rate>:<flow rate> | Packet capture sampling rate and flow | sampling rate. If <pkt rate> starts with | '@' it means that nprobe will report | the specified sampling rate but will | not sample itself as incoming packets | are already sampled on the specified | capture device at the specified rate.
