Hi Alfredo,
I reviewed the implementation of the feature (great!) and I would like to
clarify please:
1. If I understood it correctly, the number of matched packets is per given
rule, while the number of missed packets is per ring (and not per the given
rule). Is it correct, or am I wrong?
If I’m correct, can I provide a dummy rule and get the number of
missed packets on the given ring?
2. When reading “ethtool –S ethX | grep fdir_miss” or “ethtool –S ethX |
grep fdir_match” you actually get the aggregation of missed/matched packets
on the interface (ethX).
Is it possible to get the pf_ring statistics aggregated as well, per
interface, or at least per ring?
Thanks,
Amir
