Epsagon

Epsagon was an observability and application performance monitoring (APM) company, founded in 2017, that provided automated distributed tracing for serverless and containerized applications — AWS Lambda, Node.js, Python, Go, .NET, Ruby, and Java — correlating traces, metrics, and logs to help teams identify and fix problems fast without manual instrumentation. Epsagon was acquired by Cisco in 2021 and folded into Cisco's observability portfolio, after which the product was sunset. The epsagon.com developer surface (docs, dashboard, and API subdomains) no longer resolves. Its surviving public footprint is the github.com/epsagon organization and the first-party instrumentation SDKs still hosted on npm, PyPI, RubyGems, Go modules, NuGet, and Maven Central. This profile captures that remaining, verifiable footprint.

Epsagon is profiled on the APIs.io network. Tagged areas include Company, Observability, Monitoring, Application Performance Monitoring, and Distributed Tracing.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/epsagon: open an issue to ask a question, or submit a pull request to add artifacts.
