Usage
<?php use Jaeger\Factory; use OpenTracing\Formats; // init factory $factory = Factory::getInstance(); // make OpenTracing\Tracer instance $tracer = $factory->initTracer('user', '127.0.0.1', 6831); // extract parent infomation from http header $carrier = $_SERVER['HTTP_UBER_TRACE_ID']; // extract the infomation and generate a new context // only support binary carrier now $context = $tracer->extract(Formats\BINARY, $carrier); // make a new span $span = $tracer->startSpan('foo', ['child_of' => $context]); // do your job here // finish the span $span->finish(); // report infomation to jaeger $tracer->flush();
Example
Run jaeger in docker
docker run --rm -d -p 6831:6831/udp -p 16686:16686 jaegertracing/all-in-one:latest
Start demo http server
cd example
php -S 0.0.0.0:8080 HTTP.php
