Spike Protection

Understand and manage increases in your logging through Index Rate Alerting and Usage Quotas. Gain insight into anomalous data spikes to quickly pinpoint the root cause of an increase so that you can choose to store or exclude contributing logs and set limits on the volume of logs stored.

Usage Quotas

Usage Quotas

Set daily or monthly limits on the volume of logs stored. A hard quota lets you set a specific threshold to stop retaining logs and a soft quota triggers pre-defined exclusion rules to throttle the volume of logs being retained.

Index Rate Alerting

Receive notifications if the volume of indexed logs in your organization grows unexpectedly. You can monitor the index rate of logs with a fixed threshold as well as detect anomalous increases.

Powerful Exclusion Rules

Manage log volume by storing what’s important
and excluding what’s not.


Forward your logs to S3 or any other object storage for compliance or later review.
