🌊 LogTide 0.7.0

[Polliog]

This release marks a major milestone: the completion of our full observability stack. With the introduction of OTLP Metrics, LogTide now provides a unified view of logs, traces, and metrics, complemented by a new service dependency graph and enterprise-ready audit logging.

✨ What's New

📊 Full OTLP Metrics Support (#4)

• The missing piece: Complete OpenTelemetry metrics ingestion via POST /v1/otlp/metrics (Protobuf/JSON).
• All Metric Types: Native support for Gauge, Sum, Histogram, Exponential Histogram, and Summary.
• Trace Correlation: Exemplar support allows you to jump from a metric spike directly to the related traces.
• Query API & Visualization: New endpoints for aggregation (avg, sum, p95, etc.) with 7 time intervals and group-by label support.

🕸️ Service Dependency Graph (#40)

• Visual Microservices: A new force-directed graph (ECharts) to visualize how your services interact.
• Health at a glance: Nodes are color-coded based on real-time error rates (Green/Amber/Red).
• Deep Correlation: Combines span relationships with log co-occurrence analysis to map dependencies even where traces are missing.
• Inspect Panel: Click any service to see p95 latency, error rates, and upstream/downstream edges.

🛡️ Compliance Audit Log

• Traceability: Comprehensive tracking of all user actions (logins, config changes, API key rotations) for SOC 2 and ISO 27001 compliance.
• Performance: High-speed in-memory buffering with non-blocking writes to TimescaleDB.
• Searchable & Exportable: Filter events by category and export up to 10k rows to CSV for external audits.

🔧 Improvements

🎨 UX Restructuring

• Cleaner Navigation: Sidebar grouped into Observe, Detect, and Manage sections to reduce clutter.
• Unified Views: Service Map isora è un toggle inside the Traces page; Sigma rules moved to the Security hub.
• Command Palette: All 9 main sections are now accessible via keyboard shortcuts (g + initial).

📥 Flexible Ingestion

• Collector Compatibility: The /ingest endpoint now natively accepts direct arrays and wrapped formats from Vector and Fluent Bit without extra VRL/Lua scripting.

🐛 Bug Fixes

• OTLP Traces: Fixed a critical transformation bug that prevented parsing OTLP/JSON traces.
• ClickHouse Timelines: Resolved a locale mismatch causing gaps (drops to zero) in the activity charts.
• Smart Pagination: Search pages now show approximate total counts using EXPLAIN plans, preventing slow table scans on large datasets.
• SDK Patterns: Updated all dashboard examples to match the latest hub.init() patterns for JS and Python.
• Zero Warnings: Eliminated 46 TypeScript/Svelte compiler warnings for a cleaner, faster build.
