Review and apply recommendations

Adaptive Logs provides you with a list of patterns and recommendations on which logs to drop based on usage patterns. You can filter, review, and edit drop rates to suit your needs.

After reviewing, you apply the drop rates to implement the changes. The logs are then dropped upon ingestion into Grafana Cloud, reducing unnecessary log storage costs while ensuring that your observability remains intact.

Adaptive Logs recalculates its pattern list and recommended drop rates every 24 hours using a rolling 15-day window of your log ingest and query behavior. When a pattern is first detected, Adaptive Logs delays displaying it for 7 days to gather enough usage information to recommend a reasonable drop rate.

To review patterns and recommendations for drop rates for each pattern, navigate to Adaptive Logs.

On the Patterns tab, you can:

• Filter patterns by service and frequency, making it easier to decide which log lines to drop.
• If you have already applied one or more recommendations, the Adaptive Logs screen shows the drop rate currently being applied to each recommendation.
• For each pattern, you can view the query frequency, volume, drop rate, recommended, and projected savings.
• The Recommended column shows the recommended percentage of log lines to drop.
• The Current(%) column shows the percentage of lines currently being dropped, or planned to be dropped if changes have not yet been applied. For more information, see ** Fundamentals.
• Expand a pattern to view a pattern breakdown per service, including service name, percentage, savings, and volume.
• To see log lines that match the label selectors and pattern, click the Open in Explore icon for each pattern.

Apply all recommendations

Applying all recommendations is the most effective and efficient way to optimize your log management. As well as saving time and effort compared to manually reviewing and applying each recommendation individually, it also gives you immediate realization of cost savings.

To apply all recommendations, complete the following steps.

1. Click Apply all recommendations from the Adaptive Logs user interface.

2. Review the recommended drop rates

   The Apply recommended drop rate(s) dialog box provides information as to ingest volume vs projected volume and the projected savings of applying the recommendation(s).

3. Click Apply to confirm.

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