README
A simple ZipKin implementation to trace your microservices based application
// create the root span as server receive $otherSpan = new ServerReceive("get_users", "oauth2", "auth.corley:80"); // add span to the tracer $tracer->addSpan($otherSpan); // restore the root span using headers (X-B3-TraceId, X-B3-SpanId, X-B3-ParentSpanId) $otherSpan->restoreContextFromHeaders($request); // add a binary annotation on this span $otherSpan->getBinaryAnnotations()->set("http.method", "GET"); // create a new span (service call) $span = new ClientSend("getVipUser", "oauth2"); // set span as child of the root span $span->childOf($otherSpan); // add span to the tracer $tracer->addSpan($span); // add binary annotation on this span $span->getBinaryAnnotations()->set("error", true); // sign a custom event on the current span $span->add("reservedCustomer); // close the client send span $span->receive(); // close the server sent span $otherSpan->sent();
Search for a Span
When you change your context may you lost a span reference. You can use your binary annotation to search for a particular span
$rootSpan = $tracer->findOneBy("kind", "app.flow"); $span = new ClientSend("getUsers", "user.corley"); $span->setChildOf($rootSpan);
Send data using the tracer
$logger = new HttpLogger($zipkinHost); $tracer = new Tracer($logger); // ... $tracer->send();
Noop tracer
If you want to cut off the tracer your can use our NoopTracer
$logger = new NoopLogger($zipkinHost); $tracer = new Tracer($logger); // ... $tracer->send();
