# Levels

The number of compression levels to apply to old statistical data gathered from Controllers.

The `StatsCompression` section of the configuration file must also include a line for each of the levels you specify, numbered consecutively and starting from 0 (zero).

For example, if you set `Levels` to `2`, include the following lines:

    0=CompressLevel0
    1=CompressLevel1

You must then add separate sections in the configuration file, `[CompressLevel0]` and `[CompressLevel1]`, where you can specify the details of the compression for each level.

For clarity, Micro Focus recommends that you specify the name of the level that deletes statistics as `ThrowAway`, rather than `CompressLevelN`.

NOTE: If you use a shared statistics database for Coordinator and Controller components, you must not configure statistics compression in both the Coordinator and Controller configuration files.

Similarly, if you have multiple Coordinator components set up with the same configuration, for high availability, you must configure statistics compression in only one Coordinator.

For consistency, when you use a shared statistics database, Micro Focus recommends that you configure statistics compression only in the Controller components.
