V$CON_SYSSTAT

V$CON_SYSSTAT displays system statistics, including OLAP kernel statistics for the container from which it is queried. To find the name of the statistic associated with each statistic number (STATISTIC#), query the V$STATNAME view.

Column	Datatype	Description
`STATISTIC#`	`NUMBER`	Statistic number Note: Statistics numbers are not guaranteed to remain constant from one release to another. Therefore, you should rely on the statistics name rather than its number in your applications.
`NAME`	`VARCHAR2(64)`	Statistic name. You can get a complete listing of statistic names by querying the `V$STATNAME` view.
`CLASS`	`NUMBER`	A number representing one or more statistics class. The following class numbers are additive: `1` - User `2` - Redo `4` - Enqueue `8` - Cache `16` - OS `32` - Real Application Clusters `64` - SQL `128` - Debug
`VALUE`	`NUMBER`	Statistic value
`STAT_ID`	`NUMBER`	Identifier of the statistic
`CON_ID`	`NUMBER`	When queried from a non-CDB, the statistics in that instance are returned, and the `CON_ID` value is set to `0`. When queried from the root of a CDB, the statistics in every container are returned, and the `CON_ID` value indicates the container to which the statistics belong. When queried from a PDB, statistics in that PDB are returned, and the `CON_ID` value is set to the container ID for that PDB.
