Librato

Librato was a hosted metrics, monitoring and analytics service for operational data — time-series measurements, tagged metrics, dashboards ("spaces"), charts, annotations, alerts and notification services — delivered as a developer-first SaaS with a JSON REST API at metrics-api.librato.com/v1. Backed by Cowboy Ventures among others, the San Francisco company was acquired by SolarWinds in 2015 for a reported $40 million, and its metrics platform was folded into SolarWinds AppOptics — released in November 2017 — which has itself since reached end of life. The librato.com domain and every product subdomain (metrics., status., www.) now 301-redirect to the SolarWinds AppOptics end-of-life notice, the metrics-api.librato.com API host no longer resolves in DNS, and the github.com/librato organization was archived on 2024-01-02. This profile is retained as a historical record of a well-regarded developer API: the API reference source, the first-party Ruby, Python, Java and Node client libraries and the collection agents remain publicly archived and are catalogued here. The successor product is SolarWinds Observability SaaS.

Librato publishes 1 API on the APIs.io network. Tagged areas include Company, Developer Tools, Monitoring, Metrics, and Observability.

Librato’s developer surface includes API reference, documentation, getting-started guide, authentication, and 12 more developer resources.
