# Review and apply recommendations

When the system identifies an opportunity to reduce cardinality, a recommendation appears on the Recommendations page. Your first action is to review the recommendation. If you agree with it, you can apply it, knowing your existing dashboards and alerts will continue to work seamlessly.

1. Navigate to **Adaptive Metrics**.
2. Navigate to the **Rules** page.
   
   A list of rules and recommended actions appears.

### Filter rules

Use the following controls to narrow down the rules list:

- **Segment**: Filter rules by segment.
- **Filter**: Search rules by metric name.
- **Recommendation type**: Filter by recommended action: **Add** a new rule, **Keep** an existing rule, **Remove** an existing rule, or **Update** an existing rule. The rules list updates based on the type you select.
- **Show selected**: Toggle to display only the rules you have selected.

### Rules table

For each rule, the table shows the following columns:

- **Metric**: The metric name. Click the metric name or the chevron icon to open the rule details drawer.
- **Received series**: The number of active series received for this metric.
- **Current rule impact**: The active series impact of the currently applied rule.
- **Recommendation impact**: The expected active series impact of the recommended action.
- **Actions**: Apply the recommended action or view rule details.

### View rule details

Click a metric name or the chevron icon in the **Actions** column to open the rule details drawer. The drawer shows:

- **Active series stats**: Received Active Series, Removed Active Series, Stored Active Series, and the percentage Reduction.
- **Rule information**: Aggregations, labels (drop or keep), series change impact, and managed-by information. For drop rules, the drawer indicates that the entire metric is dropped.
- **Metric usage stats**: How many alerting and recording rules, dashboards, and queries use this metric.

From the drawer, you can:

- **Apply the recommended action** by clicking the action button (Add, Remove, or Update). A confirmation dialog box opens.
- **Edit the rule** by clicking **Edit rule** to modify aggregations, labels, or rule type.
- **Copy the rule as JSON** using the **Copy JSON** dropdown, which lets you copy the recommended rule or the applied rule to your clipboard.

### Apply rules

1. Select which rules you want to apply or select **Apply all recommendations**.
   
   A confirmation dialog box showing your updates opens. This dialog box displays the total expected series impact, which is useful for understanding the combined effect of all pending changes, including all recommendation types.
2. To confirm your rule updates, click **Apply**.

In the next milestone, you’ll learn how to create aggregation and drop rules.
