Chapter 8. Enabling alert data retention
You can configure a retention period for Red Hat Advanced Cluster Security for Kubernetes alerts to automatically delete older alerts and save storage costs.
8.1. Alert data retention overview
You can configure a retention period for Red Hat Advanced Cluster Security for Kubernetes alerts to automatically delete older alerts and save storage costs.
With Red Hat Advanced Cluster Security for Kubernetes, you can configure the time to keep historical alerts stored. Red Hat Advanced Cluster Security for Kubernetes then deletes the older alerts after the specified time.
By automatically deleting alerts that are no longer needed, you can save storage costs.
The alerts for which you can configure the retention period include:
- Runtime alerts, both unresolved (active) and resolved.
- Stale deploy-time alerts that do not apply to the current deployment.
- RHACS enables data retention settings by default. You can change these settings after the installation.
- When you upgrade Red Hat Advanced Cluster Security for Kubernetes, data retention settings are not applied unless you have enabled them before.
- You can configure alert retention settings by using the RHACS portal or the API.
- The deletion process runs every hour. Currently, you cannot change this.
8.2. Configuring alert data retention
