The quality of a datacenter network directly affects the stability and performance of production systems. A network outage can happen on various devices and influence different scope. The SRE needs to quickly identify the scope of the outage to determine the remediation actions.
At Baidu, we built NetRadar, a datacenter monitoring system, for this purpose. NetRadar applies multi-dimensional analysis algorithm on various kinds of network quality data to identify the scope of the network outages. In this talk, we will introduce our consideration in designing the monitoring system, as well as the analysis algorithm.
Yun Chen is a Senior Software Engineer at Baidu. Yun's work focuses on datacenter network monitoring and operation data analysis, including time-series anomaly detection and service diagnosis.
