Product Overview

The architecture of VM:DBA comprised three main components: the Monitor Engine, the Data Collector, and the Reporting Facility. The Monitor Engine was responsible for overall system management and control. The Data Collector gathered performance metrics from the Db2 for VM and VSE (SQL/DS) database and the z/VM operating system.

The Reporting Facility processed the collected data and generated reports. Communication between components occurred via z/VM internal mechanisms. Data was stored using z/VM file systems.

The system did not expose any REST APIs. The product is not supported. Organizations should migrate to modern monitoring solutions that offer more robust architectures and comprehensive features.

Consider solutions like IBM Db2 Monitoring Tools or BMC AMI Ops Monitor for Db2, which provide scalable architectures and advanced monitoring capabilities.
