Automated anomaly detection service on heterogeneous log streams
First Claim
1. A method for handling log data from one or more applications, sensors or instruments, comprising:
- receiving heterogeneous logs from arbitrary/unknown systems or applications;
generating regular expression patterns from the heterogeneous log sources using machine learning and extracting a log pattern therefrom;
generating models and profiles from training logs based on different conditions and updating a global model database storing all models generated over time, wherein generating the models comprises generating sequence order model that extracts sequential ordering relationships between patterns and volume mode that maintains a frequency distribution of logs of each pattern and detecting unusual spikes of certain patterns and report the spikes as alerts;
tokenizing raw log messages from one or more applications, sensors or instruments running a production system;
transforming incoming tokenized streams are into data-objects for anomaly detection and forwarding of log messages to various anomaly detectors; and
generating an anomaly alert from the one or more applications, sensors or instruments running a production system.
