Cache Stats: Sizes: Total=414.8218MB (434972192), Free=252.50949MB (264775392),
Max=667.3313MB (699747584), Counts: Blocks=1106, Access=273562, Hit=271671,
Miss=1891, Evictions=0, Evicted=0, Ratios: Hit Ratio=99.30874705314636%, Miss
Ratio=0.691250991076231%, Evicted/Run=NaN

Thats a metric. Should be over in metrics. Metrics does some of above but not
