logdeep

LogDeep is an open source deeplearning-based log analysis toolkit for automated anomaly detection.

Note: This repo does not include log parsing´╝îif you need to use it, please check logparser

Major features

  • Modular Design

  • Support multi log event features out of box

  • State of the art(Including resluts from deeplog,loganomaly,robustlog...)

Requirement

  • python>=3.6
  • pytorch >= 1.1.0

Quick start

git clone https://github.com/donglee-afar/logdeep.git
cd logdeep

Example of building your own log dataset
SAMPLING_EXAMPLE.md

Train & Test DeepLog example

cd demo
# Train
python deeplog.py train
# Test
python deeplog.py test

The output results, key parameters and train logs will be saved under result/ path

DIY your own pipeline

Here is an example of the key parameters of the loganomaly model which in demo/loganomaly.py
Try to modify these parameters to build a new model!

# Smaple
options['sample'] = "sliding_window"
options['window_size'] = 10

# Features
options['sequentials'] = True
options['quantitatives'] = True
options['semantics'] = False

Model = loganomaly(input_size=options['input_size'],
                    hidden_size=options['hidden_size'],
                    num_layers=options['num_layers'],
                    num_keys=options['num_classes'])
