Technical details and manufacturing context for Log Manager

Definition

The Log Manager is a critical sub-component of the Transaction Coordinator responsible for creating, maintaining, and providing access to detailed logs of all transaction-related activities. It ensures data integrity by capturing timestamps, user actions, system states, and transaction outcomes, enabling auditing, debugging, and recovery processes. It operates as the centralized repository for event data within the coordination framework. The Log Manager continuously monitors the Transaction Coordinator for events. When an event occurs (e.g., transaction initiation, data modification, commit, rollback), it captures relevant metadata (timestamp, user ID, transaction ID, action type, before/after state if applicable) and writes it as an immutable entry to a persistent storage system (e.g., database table, file system, dedicated log service). It may employ techniques like write-ahead logging (WAL) for reliability and provides APIs for querying and retrieving log data by time range, transaction, or event type. The component is designed for industrial environments, with parameters such as log retention period (30–365 days), log entry rate (1000–10000 entries/s), timestamp accuracy (±1 ms synchronized via PTP per IEC 61588), storage capacity (100–1000 GB), data integrity (99.999% per ISO 5725-1). These values are reference ranges and must be verified for the specific model and application. The Log Manager is a software component; no physical materials are specified beyond software code. It is not a standalone product but a part of the Transaction Coordinator. For procurement, verify compliance with relevant standards and confirm model-specific parameters with the legal manufacturer or supplier.

Working Principle

The Log Manager continuously monitors the Transaction Coordinator for events. When an event occurs (e.g., transaction initiation, data modification, commit, rollback), it captures relevant metadata (timestamp, user ID, transaction ID, action type, before/after state if applicable) and writes it as an immutable entry to a persistent storage system (e.g., database table, file system, dedicated log service). It may employ techniques like write-ahead logging (WAL) for reliability and provides APIs for querying and retrieving log data by time range, transaction, or event type.
