Audit logging for Azure Cosmos DB for PostgreSQL clusters via pgAudit is now generally available. Produce audit logs of events on all or some nodes in your Azure Cosmos DB for PostgreSQL cluster including writes, reads, role changes, and Data Definition Language (DDL) with the PostgreSQL audit extension. Detailed session and object audit logging is provided using the standard PostgreSQL logging facility. PostgreSQL logs can be saved to a storage account, sent to Event Hub, or queried in Azure Monitor logs.
