Field Summary

Fields
Modifier and Type	Field and Description
`static String`	`BYTES_ACCEPTED` The #of bytes in the records that were accepted by the cache.
`static String`	`BYTES_PER_WRITE` The average bytes per write (will under-report if we must retry writes).
`static String`	`BYTES_WRITTEN` The #of bytes written onto the backing channel.
`static String`	`HIT_RATE` The effective hit rate for the cache.
`static String`	`NACCEPT` The #of records that were accepted by the cache.
`static String`	`NCHANNEL_WRITE` The #of writes onto the backing channel - this is either `WriteCache` buffer instances or individual records in those `WriteCache` buffers depending on whether the `WriteCache` supports gathered writes (for the WORM, it is the #of `WriteCache` instances written, for the RW, it is the #of records written).
`static String`	`NHIT` The #of read requests that were satisfied by the cache.
`static String`	`NMISS` The #of read requests that were not satisfied by the cache.
`static String`	`WRITE_SECS` The elapsed time (in seconds) writing on the backing channel.
