The EDB Postgres Advanced Server must provide a warning to appropriate support staff when allocated audit record storage volume reaches 75 percent of maximum audit record storage capacity.
An XCCDF Rule
Description
<VulnDiscussion>Organizations are required to use a central log management system, so under normal conditions, the audit space allocated to the DBMS on its own server will not cause an issue. However, space will still be required on the DBMS server for audit records in transit, and, under abnormal conditions, this could fill up. Since a requirement exists to halt processing upon audit failure, a service outage would result. If support personnel are not notified immediately upon storage volume utilization reaching 75 percent, they are unable to plan for storage capacity expansion. The appropriate support staff include, at a minimum, the ISSO and the DBA/SA.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Remediation - Manual Procedure
Install PEM and configure a probe to monitor and notify appropriate support staff upon storage volume utilization reaching 75 percent.
Instructions to create a custom probe can be found at: https://www.enterprisedb.com/docs/pem/latest/monitoring_performance/probes/#creating-a-custom-probe
Example steps for creating a probe are below, using the thin client (browser) PEM interface. Refer also to the Supplemental Procedures document supplied with this STIG.
