# Industrial Specification: Audit Logger

## 1. Technical Definition
A software component that records and stores chronological records of system activities and access events for security monitoring and compliance purposes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-1000 events/second at 1 ms timestamp resolution**. Failure boundary: **Storage capacity exceeding 1 TB without rotation or 100,000 concurrent write operations**, Mechanism: **Disk I/O saturation causing write latency exceeding 100 ms, leading to event queue overflow and data loss**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Disk write latency exceeding 100 ms due to RAID controller failure | 8 | Event buffer overflow at 10,000 queued events, causing 5% data loss | Implement dual RAID-1 arrays with automatic failover at 50 ms latency threshold |
| Memory leak in log compression algorithm consuming 95% of allocated 8 GB RAM | 8 | Process termination by OS kernel OOM killer, creating 30-second audit gap | Implement fixed-memory ring buffer with 4 GB hard limit and compression bypass at 80% utilization |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |
