ERi/LOGR

ERi/LOGR provides a secure and controlled mechanism for application logging on z/OS, acting as middleware between applications and the z/OS System Logger. It addresses the core requirement of allowing applications to log events without needing direct authorization to the System Logger. This is achieved through a dedicated API that applications use to submit log data.

The architecture includes components for receiving log requests, validating authorization, and writing the data to the System Logger. It also provides components for reading and accessing the log data. Key architectural considerations include the integration with the z/OS security infrastructure for authentication and authorization, the performance impact of the logging process on applications, and the scalability of the logging infrastructure to handle high volumes of log data.

ERi/LOGR typically runs within an LPAR on z/OS and relies on the z/OS System Logger for storage. The specific communication protocols used between components are vendor-defined. Alternatives include native z/OS logging facilities, but ERi/LOGR offers a dedicated API and access control layer.

The administrative interface allows for user management, configuration of logging parameters, and monitoring of system health. Security is enforced through authentication methods and an access control model, ensuring that only authorized applications and users can access log data.
