Checks that AWS RDS freeable memory is being monitored.

​
Why This Matters

Unmonitored infrastructure can degrade silently until services fail. CPU spikes, memory exhaustion, storage depletion, and latency increases are early warning signs of performance issues, resource exhaustion attacks, or misconfiguration. Proactive monitoring is required by SOC 2 (CC7.1) and ISO 27001 (A.12.1.3).

What DSALTA Checks

DSALTA connects to your Amazon Web Services (AWS) environment using read-only API access and evaluates this configuration on every sync cycle. The test result appears in your Data Library → Tests dashboard:
  • Passing — The configuration meets requirements. No action needed.
  • Failing — The configuration does not meet requirements. Follow the remediation steps below.
  • Not configured — The integration is connected but the required service or feature has not been set up yet.
This test runs automatically every 24 hours. If you fix the underlying issue, DSALTA will detect the change on the next sync cycle and update the status to Passing. You can also trigger a manual sync from Settings → Integrations → Amazon Web Services (AWS).

​
How to Fix

If this test is failing, follow these steps to remediate:
  1. Sign in to the AWS Management Console and navigate to CloudWatch → Alarms → Create alarm.
  2. Click Select metric, then navigate to the RDS namespace.
  3. Find and select the FreeableMemory metric for the affected resource.
  4. Set the alarm condition to trigger when FreeableMemory FreeableMemory falls below 256 MB.
  5. Under Notification, select or create an SNS topic to deliver alerts to your team (email, Slack, or PagerDuty).
  6. Name the alarm descriptively (e.g., RDS-FreeableMemory-high) and click Create alarm.
  7. Consider upgrading to an instance class with more memory, or tuning database parameters to reduce memory consumption.
  8. Once the CloudWatch alarm is active, DSALTA will detect the configuration on the next sync and update the test status to Passing.

Frequently Asked Questions

This test runs automatically every 24 hours when the Amazon Web Services (AWS) integration is connected. You can trigger a manual sync at any time from the integration settings page.
A failing test generates an alert in your DSALTA dashboard. The assigned responsible role receives a notification. Remediate the issue before it affects your compliance posture.
Yes. If this test does not apply to your environment, you can mark it as Not Applicable with a justification. This exclusion is documented for auditors.
No. DSALTA uses read-only API access and never modifies, creates, or deletes resources in your environment. Remediation actions must be performed by your team directly in Amazon Web Services (AWS).
