SignalFx is a SaaS-based monitoring and analytics company headquartered in San Mateo, California. It allows customers to analyze, visualize, automate, and alert on metrics data from infrastructure, applications, microservices, containers, and functions. The platform uses a streaming architecture to separate metric data points into two streams: one for metadata and one for time-series values. These data streams are routed through a pub-sub bus to SignalFlow, an analytics language accessible via the SignalFx GUI and programmable APIs. The platform can handle millions of data points per second at a 1-second resolution, achieving less than 2 seconds of latency from ingestion to alerting.
