Add to EdgeLogLead -- Fast and Integrated Log Loader, Enhancer, and Anomaly Detector
This paper introduces LogLead, a tool designed for efficient log analysis. LogLead combines three essential steps in log processing: loading, enhancing, and anomaly detection. The tool leverages Polars, a high-speed DataFrame library. We currently have 7 Loaders out of which 4 is for public data sets (HDFS, Hadoop, BGL, and Thunderbird). We have multiple enhancers with three parsers (Drain, Spell, LenMa), Bert embedding creation and other log representation techniques like bag-of-words. LogLead integrates to 5 supervised and 4 unsupervised machine learning algorithms for anomaly detection from SKLearn. By integrating diverse datasets, log representation methods and anomaly detectors, LogLead facilitates comprehensive benchmarking in log analysis research. We demonstrate that log loading from raw file to dataframe is over 10x faster with LogLead is compared to past solutions. We demonstrate roughly 2x improvement in Drain parsing speed by off-loading log message normalization to LogLead. We demonstrate a brief benchmarking on HDFS suggesting that log representations beyond bag-of-words provide limited benefits. Screencast demonstrating the tool: https://youtu.be/8stdbtTfJVo
