Apply rule recommendations
Chronosphere Observability Platform includes a Recommendations page as part of the Control Plane to help identify metrics and labels with no usage or utility over the past 30 days. The utility score is calculated based on the number of configuration references to the metric, such as dashboards or monitors, and direct query executions, such as in Metrics Explorer.
Use this page to understand the impact on persisted writes and persisted cardinality when applying the recommended data optimizations. After applying optimizations, it might take up to 150 minutes to see impacts to cardinality. Impacts to persisted writes are immediate. The aggregation rules on this page incorporate labels that appear together in the total cardinality calculation.
Drop rule recommendations
To apply drop rule recommendations:
- In the navigation menu, click Go to Admin and then select Control > Recommendations.
- In the left navigation under Data optimizations, click the drop rule recommendations.
- Select one or more metrics to calculate the estimated impact on reducing persisted writes and persisted cardinality. All metrics are selected by default.
- Click Create Drop Rule to create a drop rule definition that contains the selected metrics.
- In the Add Drop Rule drawer, choose whether the rule drops data with any value, or if it meets a particular value.
- Click Review to review your changes.
- Select the checkbox to indicate that you’ve reviewed the rule, and then click Save Rule.
The drop rule is created and displays in the Drop Rules page.
Rollup rule recommendations
To apply rollup rule recommendations:
- In the navigation menu, click Go to Admin and then select Control > Recommendations.
- In the left navigation under Data optimizations, click the rollup rule recommendations.
- Select a single metrics to calculate the estimated impact on reducing persisted writes and persisted cardinality.
- Click Create Rollup Rule to create a rollup rule definition that contains the selected metric.
- Complete the steps to create a rollup rule.
