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 87GB in size. We thus host only a small sample (2k lines) on Github for each dataset.

If you use our loghub datasets in your research for publication, please kindly cite the following paper.

If you are interested in these datasets, please request the raw logs at Zenodo. Please kindly note that the affiliation information is minimally required for your data request.
