SignalFx

SignalFx is a cloud monitoring and observability platform for modern infrastructure and microservices, founded in 2013 and acquired by Splunk in October 2019. It ingests high-resolution time-series metrics, events, and traces and applies real-time streaming analytics (the SignalFlow computation engine) to power dashboards, charts, detectors, and alerts. The platform is now delivered as Splunk Observability Cloud. SignalFx exposes a realm-based REST API (metadata, detectors, charts, dashboards, integrations, tokens, SLOs) at api.{realm}.signalfx.com, a data-ingest API at ingest.{realm}.signalfx.com, and a SignalFlow streaming API at stream.{realm}.signalfx.com, all authenticated with an X-SF-Token header. First-party client libraries ship for Go, Python, Node.js, Java, and Ruby.

SignalFx publishes 1 API on the APIs.io network. Tagged areas include Company, Observability, Monitoring, Metrics, and Time Series.

SignalFx’s developer surface includes documentation, API reference, getting-started guide, engineering blog, signup flow, pricing, support, and 20 more developer resources.
