Elastic Stack is a comprehensive log analysis solution that helps users efficiently retrieve, process, and analyze search data. The book provides a comprehensive overview of Elastic Stack (Elastic ML) machine learning functions for both time series data analysis and for classification, regression and outlier detection. Machine learning concepts are explained in an understandable and accessible language. Time series analysis for various types of data, such as log files, network flows, application metrics, and financial data, is discussed. Describes using Elastic ML to log, secure, and track metrics. After reading, you will gain hands-on experience sharing machine learning technology and Elastic Stack, as well as the knowledge needed to incorporate machine learning into your distributed data retrieval and analysis platform.
