Network monitoring combining client-based and network-based signals

Abstract

A monitoring service analyzes client-based monitoring data in correlation with network-based monitoring data for paths between two endpoints in a network upon request from a client. The endpoint can be any valid private IP address or DNS name where traffic is to be sent. Clients may define parameters for the monitoring, including thresholds for identifying network issues based on the client-based monitoring data. Different levels of network-based monitoring may be performed responsive to results of the correlation and continued performance determinations relative to the thresholds. The client-based and network-based monitoring data may include reports of performance signals, such as packet loss and round-trip time or other measured latency, as well as events such as connection issues and timeouts. The monitoring data from the different sources can be compared to determine whether a network issue is present in the network or outside of the network/in the client.
