END_TIME	DATE	End time of the interval
INTSIZE_CSEC	NUMBER	Interval size (in hundredths of a second)
GROUP_ID	NUMBER	Metric Group ID. Refer to the V$METRICNAME view for the name of the group.
ENTITY_ID	NUMBER	Entity ID for the metric in question. The value of the Entity ID depends upon the metric group. (See the following table for an explanation of possible values.)
ENTITY_SEQUENCE	NUMBER	Entity Sequence number for the metric in question. The value of the Entity Sequence depends upon the metric group. (See the following table for an explanation of possible values.)
METRIC_ID	NUMBER	Metric ID
METRIC_NAME	VARCHAR2(64)	Metric Name. This is the statistic that is captured for the entity.
VALUE	NUMBER	Value of the statistic between BEGIN_TIME and END_TIME
METRIC_UNIT	VARCHAR2(64)	Unit for the VALUE
CON_ID	NUMBER	The ID of the container to which the data pertains. Possible values include: 0: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs. 1: This value is used for rows containing data that pertain to only the root n: Where n is the applicable container ID for the rows containing data
