SignalFx was acquired by Splunk in October 2019. See Splunk SignalFx for more information.
SignalFx Distributed Tracing intends to be instrumentation agnostic; supporting & ingesting variety of popular open instrumentation libraries including OpenTracing, Zipkin & OpenCensus. So long as the tracer configured to send spans to SignalFx ingest endpoint uses the Zipkin v1/2 JSON wire format or Jaeger Thrift format, we will accept spans irrespective of how they were instrumented - via one of the above mentioned open libraries or a homegrown one. Our goal is to build on the shoulders of giant communities rather than re-invent the wheel with proprietary libraries/agents and give customers choice to decide what works for them without worrying about vendor lock-in.
For customers who have not yet instrumented their code, our default recommendation is to use OpenTracing to instrument since it has a growing ecosystem of library owners & frameworks instrumenting their code with it & use Jaeger tracer libraries to export spans to us - both of these are CNCF projects with a rapidly growing community behind them.
RPC layer(s) and service/web framework(s) are the best places to start when thinking about how to go about instrumentating your application - both of these will likely have a large coverage area and touch a significant number of transaction paths to give you baseline tracing coverage and visualize an end-to-end trace with a service-map.
Next you should identify services critical to your business and look for areas not covered by rpc or service/web frameworks. Within these services, identify high value transactions and critical paths - instrument enough of these.
This repository contains a set of simple example applications that demonstrate using OpenTelemetry or SignalFx with various open source tracers. They are broken down by language/platform.
For customers who have not instrumented their applications, or have done so in an OpenTracing-compatible fashion, we offer several SignalFx Tracing libraries. Their detailed documentation is available in their respective source locations:
Examples of those auto-instrumentation techniques are available in this repository:
