Zipkin is a distributed tracing system. It helps gather timing data needed to troubleshoot latency problems in microservice architectures.
It manages both the collection and lookup of this data. Zipkin’s design is based on the Google Dapper paper.
OpenCensus Python has support for this exporter available through package opencensus.trace.exporters.zipkin_exporter
Creating the exporter
To create the exporter, we'll need to:
- Create an exporter in code
- Have the Zipkin endpoint available to receive traces
#!/usr/bin/env python from opencensus.ext.zipkin.trace_exporter import ZipkinExporter from opencensus.trace.tracer import Tracer def main(): ze = ZipkinExporter( service_name="service-a", host_name="localhost", port=9411, endpoint="/api/v2/spans") tracer = Tracer(exporter=ze) with tracer.span(name="doingWork") as span: for i in range(10): pass if __name__ == "__main__": main()
Viewing your traces
Please visit the Hypertrace UI endpoint http://localhost:2020.
