Loghub-2.0 (LogPub)

Loghub-2.0 is a collection of large-scale annotated datasets for log parsing based on Loghub, proposed by LogPAI.

Based on Loghub-2.0, we propose a more comprehensive benchmark of log parsers. The detailed evaluation results could be found at RQ_experiments 🔗.

Datasets download

Please first download the full datasets of Loghub-2.0 via Zenodo.

Then, you need to put these datasets into full_dataset/ following the format of 2k_dataset.

Requirements

Owing to the large scale of the benchmark in the experiments, the requirements of the benchmark of all log parsers are:

• At least 16GB memory.
• At least 100GB storage.
• GPU (for LogPPT and UniParser).

Installation

1. Install python >= 3.8
2. pip install -r requirements.txt

One-Click Results Reproduction

Running the entire benchmark using Loghub-2.0 datasets requires more than 48 hours to complete.

Note that if you would like to evaluate your parser, one can easily put their parsed results following the format as the files shown in result/, and run our evluation code.

Large-scale benchmarking

If you woud like to re-run all parsers using Loghub-2.0, please follow our large-scale benchmarking steps.

Quick Demo using Drain

We give a demo script to run Drain on both Loghub-2k and Loghub-2.0, this will takes about 2-3 hours.

cd benchmark/
./demo.sh

Evaluation of all 15 parsers

One can follow the steps to evaluate all parsers using Loghub-2k or the proposed Loghub-2.0 datasets. The overall time cost is more than 48 hours.

• Run all statistic-based log parsers on Loghub-2k

cd benchmark/
./run_statistic_2k.sh

• Run all statistic-based log parsers on Loghub-2.0

cd benchmark/
./run_statistic_full.sh

• Run Semantic-based log parsers: LogPPT & UniParser

  Since these methods are quite different with other log parsers, and they requires a GPU to support efficient parsing, we seperate their environments from other log parsers. Please refer to the README file of LogPPT or UniParser to use one-click script to parse and evaluate each log parsers respectively.
