Request Analysis

Every Request. Analyzed Automatically.

A 30+ rule engine surfaces anti-patterns, PII exposure, and optimization opportunities from your live traffic. No agents, no SDKs, no code changes.

Three-Tier Capture Architecture

100% visibility with zero performance impact.

Hot Path

Every request captured with atomic counters. Zero allocations, never blocks.

Command counts, latency, bytes, hot keys

Force Sampling

Errors, slow queries, and dangerous commands always captured.

Bounded at 10K events per window

Burst Capture

Full traffic sampling triggered by anomaly detection.

Statistically representative via reservoir sampling

Real-Time Threat Detection with Eve

Zero-instrumentation analytics that sits in the proxy layer. No code changes, no agents to deploy, no SDK to integrate. Enable a feature flag and insights start flowing.

Anti-Pattern Detection

Eve watches your traffic at two levels: per-connection sequences and per-endpoint aggregates. Hot key detection via Space-Saving sketch (64-entry, O(1) lookup). Key pattern extraction with LRU cache (10k entries).

N+1 queriesHot keys (> 15% traffic)Missing TTLsSlow queries (> 10ms)High fanout (100+ keys)Dangerous commands

PII Detection

Real-time regex-based scanning for sensitive data in keys and values. Detects emails, credit card numbers, SSNs, phone numbers, and API keys with automatic redaction before storage.

30+ Rule Recommendation Engine

Not dashboards to stare at. Actionable recommendations with severity levels, confidence scores, and estimated monthly cost savings. Covers write-heavy patterns, oversized values, hot keys, large hash operations, and read replica candidates.

Write-heavy, never-read patternsOversized values (> 64 KB)Hot key concentration (> 15%)Large hash ops (> 5 KB)Read replica candidates (> 70% reads)Missing TTLs (> 80% no TTL)

Zero Instrumentation

Analytics sits in the proxy layer. No agents to deploy, no SDKs to integrate, no code to change. Point your traffic through Eve and insights start flowing.

Live Recommendations for Running Systems

Eve provides the first real-time recommendation system that provides severity, confidence, and actionable improvements.

High Severity
Confidence: 87%

Write-Heavy, Never-Read Pattern

Pattern: session:*:temp

Writing 12,400/day with 0 reads. Consider removing or adding a TTL.

Critical
Confidence: 94%

N+1 Query Detected

Endpoint: /api/v1/orders

42 sequential identical queries per request. Batch into a single query to reduce latency by ~85%.

Medium
Confidence: 72%

Read Replica Candidate

Endpoint: analytics-db-primary

92% read ratio across 340K daily requests. Route reads to a replica to reduce primary load.

Anomaly Detection & Observability

Three-stage anomaly detection with adaptive metadata collection. Full OpenTelemetry integration for distributed tracing and metrics export.

Jensen-Shannon Divergence

Compares real-time command distribution against baseline. Watch state at 2% divergence, critical at 5%.

3-window confirmation before alerting

5-window cooldown before reset

5-minute confirmation memory bridging gaps

Adaptive Metadata Polling

Three-frequency collection that accelerates up to 8x during anomalies with hysteresis to prevent flapping.

High: 60s · Medium: 30min · Low: 24h

Normal → Watch → Elevated → Critical

ClickHouse storage with 60s flush cycles

OpenTelemetry Integration

Full OTel support with distributed context propagation, structured logging, and OTLP metric export.

Health snapshots every 60s per endpoint

ops/sec, p50/p99/p999 latency, error rate

Datadog integration out of the box
