Loglizer is a machine learning toolkit for log-based anomaly detection, implementing classic supervised and unsupervised models (LR, Decision Tree, SVM, PCA, Invariants Mining, etc.) from the ISSRE'16 research paper. It provides a pipeline covering log parsing, feature extraction, and anomaly detection for research on automated failure diagnosis.

Use cases

• detect anomalies in system logs automatically
• train machine learning models on log data for failure prediction
• research log-based anomaly detection techniques
• diagnose system failures from runtime logs
• benchmark anomaly detection models on log datasets
• extract features from structured log sequences

When to choose

• you are doing academic research on log anomaly detection
• you need implementations of classic log analysis models like PCA or invariant mining
• you want a reproducible pipeline from parsed logs to anomaly predictions
• you work with benchmark log datasets like HDFS or BGL

When to avoid

• you need a production-grade, real-time log monitoring service
• you want plug-and-play integration with your existing observability stack
• you need actively developed features or commercial support
• you require deep learning based log analysis models
