Opentracing Support
Vulcand has support for open tracing via the Jaeger client
libraries. Users who wish
to use tracing support should use the --enableJaegerTracing flag and must
either run the Jaeger client listening on localhost:6831/udp or set the
environment variables JAEGER_AGENT_HOST and JAEGER_AGENT_POST. (See the
Jaeger client libraries
for all available configuration environment variables.
When enabled vulcand will create 2 spans, one span called vulcand which
covers the entire downstream request. The other span called middleware which
only spans the processing of the middleware before the request is routed
downstream.
