The CONFIG RESETSTAT command does not reset the following stats:
2.6: stat_peak_memory (bytes) stat_evicted_keys (counter)
2.8 adds: stat_sync_full (counter) stat_sync_partial_ok (counter) stat_sync_partial_err (counter)
Comment From: yoav-steinberg
stat_peak_memory isn't reset by design.
All the reset were fixed here e150ec7d0c83d56f81496084b2e5f119c958ab6f.
Closing.
