Title: Luba Cherbakov: Innovator in Performance Anomaly Detection

Introduction

Luba Cherbakov is a notable inventor based in McLean, Virginia, who has made significant contributions to the field of application performance analysis. With a total of four patents to her name, she has developed innovative approaches to detect and analyze performance anomalies in client-server based applications.

Latest Patents

Cherbakov's latest patents focus on detecting and analyzing performance anomalies in client-server connections via a network. One of her approaches involves determining a status code of a response sent by a server to a client, measuring the round trip latency time (RTT) of the response, and assessing the timeout of the connection between the client and server. By utilizing a k-means clustering algorithm, she clusters RTT values into lower and higher categories, allowing for the identification of anomalies when an RTT value exceeds a predetermined threshold. Additionally, she analyzes log entries and environmental factors to determine potential root causes of failures that lead to these anomalies.

Another patent by Cherbakov also addresses performance anomalies by determining the request time and the Internet Protocol (IP) address of the client. This method selects relevant log entries based on the request time and IP address, and assesses the response code, RTT, and connection timeout to detect anomalies. Through temporal and textual analyses of log entries associated with the anomaly, she identifies candidate root causes of failures.
