⚡ OpenTelemetry & Micrometer AIOps

AI-Powered Observability & Log Analysis

OpenCrawling leverages native Spring Boot 4, OpenTelemetry (OTel) correlated spans, and Spring AI Model Context Protocol (MCP) tools to transform complex multi-threaded trace telemetry into automated Root Cause Analysis (RCA) reports.

🔍 Correlated OTel Traces

Every ingestion pipeline stage—Scanning, Extracting, Chunking, Embedding, and Indexing—generates distributed OpenTelemetry spans correlated by unique jobId.

          Tracing: Scanning (450ms) → Extracting (1200ms) → Chunking (300ms) → Embedding (1800ms) → Indexing (650ms)
        

🛠️ System MCP Tools

Exposes system-level Model Context Protocol tools exclusively to the Admin Copilot, enabling LLM agents to query live traces, exception stack traces, and Micrometer performance metrics.
