Intelligent Event Analysis Framework ( RAG Works )

Posted on by lechuck park

This diagram illustrates a sophisticated Intelligent Event Processing architecture that utilizes Retrieval-Augmented Generation (RAG) to transform raw system logs into actionable technical solutions.

Architecture Breakdown: Intelligent Event Processing (RAG Works)

1. Data Inflow & Prioritization

  • Data Stream (Event Log): The system captures real-time logs and events.
  • Importance Level Decision: Instead of processing every minor log, this “gatekeeper” identifies critical events, ensuring the AI engine focuses on high-priority issues.

2. The RAG Core (The Reasoning Engine)

This is the heart of the system (the pink area), where the AI analyzes the problem:

  • Search (Retrieval): The system performs a Semantic Search and Top-K Retrieval to find the most relevant technical information from the Vector DB.
  • Augmentation: It injects this retrieved context into the LLM (Large Language Model) via In-Context Learning, giving the model “temporary memory” of your specific systems.
  • CoT Works (Chain of Thought): This is the “thinking” phase. It uses a Reasoning Path to analyze the data step-by-step and performs Conflict Resolution to ensure the final answer is logically sound.

3. Knowledge Management Pipeline

The bottom section shows how the system “learns”:

  • Knowledge Documents: Technical manuals, past incident reports, and guidelines are collected.
  • Standardization & Chunking: Data is broken down into manageable “chunks” and tagged with metadata.
  • Vector DB: These chunks are converted into mathematical vectors (embeddings) and stored, allowing the engine to search for “meaning” rather than just keywords.

4. Final Output

  • RCA & Recovery Guide: The ultimate goal. The system doesn’t just say there’s an error; it provides a Root Cause Analysis (RCA) and a step-by-step Recovery Guide to help engineers fix the issue immediately.

Summary

  1. Automated Intelligence: It’s an “IT First Responder” that converts raw system noise into precise, logical troubleshooting steps.
  2. Context-Aware Analysis: By combining RAG with Chain-of-Thought reasoning, the system “reads the manual” for you to solve complex errors.
  3. Data-Driven Recovery: The workflow bridges the gap between massive event logs and actionable Root Cause Analysis (RCA) to minimize downtime.

SCR(Short Circuit Ratio)

Posted on by lechuck park

This image is an infographic that explains SCR (Short Circuit Ratio) and why it matters for AI/data center power stability. The main idea is: SCR compares grid strength at the connection point (PCC) against the data center’s load size—lower SCR means more voltage instability.

1) Top: SCR formula

  • SCR = Ssc / Pload
    • Ssc: Short-circuit MVA at the PCC
      → the grid’s strength / stiffness at the point where the data center connects
    • Pload: Rated MW of the data center load
      → the data center’s rated power demand

2) Middle: What high vs. low Ssc means (data center impact)

  • High Ssc (strong grid)
    → the grid can absorb sudden load changes, so voltage dips are smaller and operation is more stable.
  • Low Ssc (weak grid)
    → the same load change causes larger voltage swings, increasing the risk of trips, protection actions, or UPS transfers.

3) PCC definition (center-lower)

  • PCC (Point of Common Coupling)
    → the grid-to-data-center “handoff point” where voltage and power quality are assessed.

4) Bottom: Grid categories by SCR

  • Strong Grid: SCR > 3
    → strong voltage support; waveform remains stable even with load fluctuations.
  • Weak Grid: 2 ≤ SCR < 3 (shown as 3 > SCR ≥ 2 in the image)
    → voltage is sensitive; small load changes can cause noticeable voltage variation.
  • Very Weak Grid: SCR < 2
    → difficult to maintain stable operation; high risk of instability or (in extreme cases) grid collapse.

summary

  1. SCR = grid strength at PCC (Ssc) ÷ data center load (Pload).
  2. Higher SCR means smaller voltage dips and more stable operation.
  3. Lower SCR increases power-quality risk (voltage swings, trips, UPS transfers).

Intelligent Event Analysis Framework ( Who the First? )

Posted on by lechuck park

Intelligent Event Processing System Overview

This architecture illustrates how a system intelligently prioritizes data streams (event logs) and selects the most efficient processing path—either for speed or for depth of analysis.

1. Importance Level Decision (Who the First?)

Events are categorized into four priority levels ($P0$ to $P3$) based on Urgency, Business Impact, and Technical Complexity.

  • P0: Critical (Immediate Awareness Required)
    • Criteria: High Urgency + High Business Impact.
    • Scope: Core service interruptions, security breaches, or life-safety/facility emergencies (e.g., fire, power failure).
  • P1: Urgent (Deep Diagnostics Required)
    • Criteria: High Technical Complexity + High Business Impact.
    • Scope: VIP customer impact, anomalies with high cascading risk, or complex multi-system errors.
  • P2: Normal (Routine Analysis Required)
    • Criteria: High Technical Complexity + Low Business Impact.
    • Scope: General performance degradation, intermittent errors, or new patterns detected after hardware deployment.
  • P3: Info (Standard Logging)
    • Criteria: Low Technical Complexity + Low Business Impact.
    • Scope: General health status logs or minute telemetry changes within designed thresholds.

2. Processing Paths: Fast Path vs. Slow Path

The system routes events through two different AI-driven pipelines to balance speed and accuracy.

A. Fast Path (Optimized for P0)

  • Workflow: Symbolic Engine → Light LLM → Fast Notification.
  • Goal: Minimizes latency to provide Immediate Alerts for critical issues where every second counts.

B. Slow Path (Optimized for P1 & P2)

  • Workflow: Bigger Engine → Heavy LLM + RAG (Retrieval-Augmented Generation) + CoT (Chain of Thought).
  • Goal: Delivers high-quality Root Cause Analysis (RCA) and detailed Recovery Guides for complex problems requiring deep reasoning.

Summary

  1. The system automatically prioritizes event logs into four levels (P0–P3) based on their urgency, business impact, and technical complexity.
  2. It bifurcates processing into a Fast Path using light models for instant alerting and a Slow Path using heavy LLMs/RAG for deep diagnostics.
  3. This dual-track approach maximizes operational efficiency by ensuring critical failures are reported instantly while complex issues receive thorough AI-driven analysis.

Intelligent Event Processing Architecture Analysis

The provided diagrams, titled Event Level Flow and Intelligent Event Processing, illustrate a sophisticated dual-path framework designed to optimize incident response within data center environments. This architecture effectively balances the need for immediate awareness with the requirement for deep, evidence-based diagnostics.

1. Data Ingestion and Intelligent Triage

The process begins with a continuous Data Stream of event logs. An Importance Level Decision gate acts as a triage point, routing traffic based on urgency and complexity:

  • Critical, single-source issues are designated as Alert Event One and sent to the Fast Path.
  • Standard or bulk logs are labeled Normal Event Multi and directed to the Slow Path for batch or deeper processing.

2. Fast Path: The Low-Latency Response Track

This path minimizes the time between event detection and operator awareness.

  • A Symbolic Engine handles rapid, rule-based filtering.
  • A Light LLM (typically a smaller parameter model) summarizes the event for human readability.
  • The Fast Notification system delivers immediate alerts to operators.
  • Crucially, a Rerouting function triggers the Slow Path, ensuring that even rapidly reported issues receive full analytical scrutiny.

3. Slow Path: The Comprehensive Diagnostic Track

The Slow Path focuses on precision, using advanced reasoning to solve complex problems.

  • Upon receiving a Trigger, a Bigger Engine prepares the data for high-level inference.
  • The Heavy LLM executes Chain of Thought (CoT) Works, breaking down the incident into logical steps to avoid errors.
  • This is supported by a Retrieval-Augmented Generation (RAG) system that performs a Search across internal knowledge bases (like manuals) and performs an Augmentation to enrich the LLM prompt with specific context.
  • The final output is a comprehensive Root Cause Analysis (RCA) and an actionable Recovery Guide.

Summary

  1. This architecture bifurcates incident response into a Fast Path for rapid awareness and a Slow Path for in-depth reasoning.
  2. By combining lightweight LLMs for speed and heavyweight LLMs with RAG for accuracy, it ensures both rapid alerting and reliable recovery guidance.
  3. The integration of symbolic rules and AI-driven Chain of Thought logic enhances both the operational efficiency and the technical reliability of the system.
