Self-Hosted Log Anomaly Detection: Drain3 vs Loglizer vs LogDeep

Introduction

Modern applications generate terabytes of log data daily — HTTP access logs, application error logs, database query logs, system audit trails, and security event logs. Within this ocean of mostly routine entries, a handful of anomalous log lines may indicate a critical failure, a security breach, or a performance regression. Finding these needles in the log haystack is the core challenge of log anomaly detection.

Self-Hosted Metric Anomaly Detection: Luminol vs EGADS vs Surus

Introduction

Modern infrastructure generates millions of metrics every minute — CPU utilization, request latency, error rates, queue depths, and hundreds more. Manually setting static alert thresholds (“alert if CPU > 80%”) breaks down at scale because what’s normal at 2 PM on Tuesday differs dramatically from normal at 3 AM on Sunday.
