Client supports request tracing, giving you an end-to-end view of a request’s lifecycle. The client supports gRPC, HTTP and WebSocket protocols.
from jina import Flow f = Flow( tracing=True, traces_exporter_host='http://localhost', traces_exporter_port=4317, ) with f: f.post('/')
from jina import Client # must match the Flow setup c = Client( tracing=True, traces_exporter_host='http://localhost', traces_exporter_port=4317, ) c.post('/')
Each protocol client creates the first trace ID which will be propagated to the
Gateway then creates child spans using the available trace ID which is further propagated to each Executor request. Using the trace ID, all associated spans can be collected to build a trace view of the whole request lifecycle.
Using custom/external tracing context
Client doesn’t currently support external tracing context which can potentially be extracted from an upstream request.
