We are using DataStax Enterprise Server 2.2.1, opscenter-2.1.2. OPSCenter is not displaying the KeyCache Hit Rate for the column family.
Running nodetool -h localhost info on the server does show
Key Cache : size 6882816 (bytes), capacity 104857584 (bytes), 509217 hits, 617744 requests, 0.824 recent hit rate, 14400 save period in seconds
Row Cache : size 0 (bytes), capacity 0 (bytes), 0 hits, 0 requests, NaN recent hit rate, 0 save period in seconds
So why is OPSCenter not displaying any information about the KeyCache Hit Rate?
