V$SYSMETRIC displays the system metric values captured for the most current time interval for both the long duration (60-second) and short duration (15-second) system metrics.
V$SYSMETRIC_HISTORY displays all system metric values available in the database. Both long duration (60-second with 1 hour history) and short duration (15-second with one-interval only) metrics are displayed by this view.
V$SYSMETRIC_SUMMARY displays a summary of all system Metric values for the long-duration system metrics. The average, maximum value, minimum value, and the value of one standard deviation for the last hour are displayed for each metric item.

DBA_HIST_SYSMETRIC_HISTORY externalizes all available history of the system metric values for the entire set of data kept in the database. This view contains snapshots of V$SYSMETRIC_HISTORY.

DBA_HIST_SYSMETRIC_SUMMARY displays a history of statistical summary of all metric values in the System Metrics Long Duration group. This view contains snapshots of V$SYSMETRIC_SUMMARY.
