[Nfd-dev] CS hit ratio on NDN testbed nodes

[Junxiao Shi]

Hi Hamed

No, it is impossible to derive CS hit ratio from the existing counters. The only way is to parse NFD logs when Forwarder is at DEBUG level.

I agree with the usefulness of CS hits and CS misses counters. This is now tracked as NFD Feature 4219 <https://redmine.named-data.net/issues/4219>. You may watch this issue on Redmine to get updates.

Yours, Junxiao

Actually, I need to know what percentage of Interests are satisfied by CS for the currently running applications. Can this probably be deduced from some counters of Interest, Data and Nacks on the NFD status page for each node?
