Log anomaly dataset. Firstly, the model parses raw logs using the Drain3 tool. Conventional machine learning and deep learning methods assume consistent distributions between the training and testing data, adhering to a closed-set recognition paradigm. Jan 30, 2025 · Furthermore, the majority of methods depend on supervised learning, which hinders the detection of abnormal logs in large, unlabeled datasets. This dataset contains 4000 rows of corporate financial records across multiple financial dimensions. Fig. . Dataset Summary AnomalyMachine-50K is a fully synthetic industrial machine sound anomaly detection dataset designed for research on acoustic monitoring, predictive maintenance, and sound event detection. To address these limitations, this paper proposes a novel semi-supervised log anomaly detection model, termed LogCTBL (CNN-TCN-Bi-LSTM). Aug 12, 2024 · Correspondingly, automated log anomaly detection has become a crucial means to ensure stable network operation and protect networks from malicious attacks or failures. We generate a comprehensive dataset of logs, metrics, and traces from a production microservice system to enable the exploration of multi-modal fusion methods that integrate multiple data modalities. Results of model performance under HDFS and BGL dataset divisions. Since the first release of these logs, they have been downloaded 90,000+ times by more than 450 organizations from both industry (35%) and academia (65%). Lyu. Loghub: A Large Collection of System Log Datasets for AI-driven Log Analytics. 7. A structured classification is proposed that categorizes UAV state estimation anomalies into four classes: mechanical and electrical, external position, global position, and altitude anomalies. We propose ContraLog, a parser In evaluation, we introduce Spark-SDA, a new dataset featuring more diverse log templates and excessively long sequences, alongside the HDFS log dataset. Additionally, other datasets could facilitate research on log parsing, log compression, and unsupervised methods for anomaly detection. It is designed to help identify unusual patterns, potential failures, or security issues in infrastructure environments by analyzing large-scale log datasets. - "SLNALog: A Log Anomaly Detection Scheme Based on Swift Layer Normalization Attention Mechanism for Next-Generation Power Communication Networks" Log files record computational events that reflect system state and behavior, making them a primary source of operational insights in modern computer systems. The dataset is structured for two tasks: general anomaly detection (normal vs anomalous) and fine-grained recognition of 13 anomalous activities. Automated anomaly detection on logs is therefore critical, yet most established methods rely on log parsers that collapse messages into discrete templates, discarding variable values and semantic content. The following sections show how to get the data sets, parse and group them into Apr 16, 2025 · We provide a dataset that supports research on anomaly detection and architectural degradation in microservice systems. We further evaluate LogBoost using established log-based anomaly detection models. The log anomaly detection model was tested using HDFS log data and was able to achieve test set precision, recall, and F-score values all greater than 99%. This repository contains scripts to analyze publicly available log data sets (HDFS, BGL, OpenStack, Hadoop, Thunderbird, ADFA, AWSCTD) that are commonly used to evaluate sequence-based anomaly detection techniques. Loghub: Jieming Zhu, Shilin He, Pinjia He, Jinyang Liu, Michael R. Jul 12, 2024 · With this experimental study we aim to answer the following two research questions: How do anomalies manifest themselves in common log data sets? What are drawbacks that render these data sets inadequate for evaluation of sequence-based anomaly detection techniques? Please cite the following two papers if you use the loghub datasets in your research. It is designed for evaluating financial statement reliability, detecting anomalies, and supporting quality assessment analysis. Training videos are weakly labeled at the video level. Log Anomaly Detection Model: CNN model using the feature matrices as inputs and trained using labelled log data. While GMMs are well-established, they often struggle to manage the high dimensionality and complexity inherent in well log datasets, resulting in suboptimal anomaly detec-tion. Common Log datasets for Sequence based Anomaly Detection The dataset comprises both normal and anomalous flights without synthetic manipulation, making it uniquely suitable for realistic anomaly detection tasks.
