public class EnvironmentStats extends Object implements Serializable
The statistics are logically grouped into several categories. Viewing the
statistics through toString()
displays the values
in these categories, as does viewing the stats through the JEMonitor mbean.
Viewing the stats with toStringVerbose()
will
provide more detailed descriptions of the stats and stat categories.
The current categories are:

The log utilization is the percentage of the total log size (all .jdb
files) that is utilized or active. The remaining portion of the log
is obsolete. The log cleaner is responsible for keeping the log
utilization below the configured threshold,
EnvironmentConfig.CLEANER_MIN_UTILIZATION
.
This statistic is computed every time the log cleaner examines the
utilization of the log, in order to determine whether cleaning is
needed. The frequency can be configured using
EnvironmentConfig.CLEANER_BYTES_INTERVAL
.
Note that the size of the utilized data in the log is always greater than the amount of user data (total size of keys and data). The active Btree internal nodes and other metadata are also included.
