And a follow up question: What’s the difference between these three stats? Time 34962.2, average vectors/node 14.93, last 128 main loops 0.00 per node 0.00 I suppose the first one is number of vectors processed / number of calls. But what about the second and the third one?

Hi everyone, I’m now looking at vpp/vpp-api/vpp_get_metrics.c, which shows the following stats: 1. Vector_rate(vector_counts_per_main_loop / node_counts_per_main_loop): So based on my understanding this shows the average vector length per node per main loop(During the window of last X main loops) ranging from 0 – 255 (For a vector size of 256)? And when it reaches 255 it means that VPP is running in 100% capacity? 2. Input_rate(Aggregate Rx rate): This means the number of packets received from dpdk-input node per second during the set interval? 3. Error_rate(Significant Error rate): This means the number of error packets from all nodes per second during the set interval? (Shown in vppctl sh err?) There’s not much said about it, and I just tried to guess it from the source code. I hope a clarification can be made on these stats so everyone can understand it without confusions. Thanks, Andrew
