# Track Preferences and Activation Metrics with Subscriber-to-LMO Feature Parameters

Use subscriber-to-LMO feature parameters to track feature activation in your subscriber’s org. Parameter values are assigned on the subscriber’s end and then sent to your LMO. To collect the values, update the feature parameters in your subscriber’s org using Apex code. Check with your legal team before obtaining activation metrics from your customers. Use activation metrics to collect only aggregated data regarding feature activation.

- `System.FeatureManagement.setPackageBooleanValue('YourBooleanFeatureParameter', booleanValue);`
- `System.FeatureManagement.setPackageDateValue('YourDateFeatureParameter', datetimeValue);`
- `System.FeatureManagement.setPackageIntegerValue('YourIntegerFeatureParameter', integerValue);`

**note:** The Value\_\_c field on subscriber-to-LMO feature parameters is editable in your LMO. But don’t change it. The changes don’t propagate to your subscriber’s org, so your values will be out of sync.

You can view the value of a subscriber-to-LMO feature parameter from the [Subscriber Support Console](https://developer.salesforce.com/docs/atlas.en-us.pkg2_dev.meta/pkg2_dev/lma_subscriber_support_overview.htm).
