Loghub maintains a collection of system logs, which are freely accessible for research purposes. Some of the logs are production data released from previous studies, while some others are collected from real systems in our lab environment. Wherever possible, the logs are NOT sanitized, anonymized or modified in any way. All these logs amount to over 77GB in total.
🔭 If you use the loghub datasets in your research for publication, please kindly cite the following paper.
