opentracing-grpc-interceptor

Grpc client interceptor for PHP makes it easy to add OpenTracing support to gRPC-based calls.

Currently supports only UnaryUnary calls.

Usage example

use Grpc\Internal\InterceptorChannel;
use OpenTracingInterceptor\ClientInterceptor;
use Acme\Tracer;
use Foo\Bar\SomeGrpcClient;
use Foo\Bar\SomeGrpcMethodArgs;

$host = 'grpc.server.com:1313';
$tracer =  new Tracer();

$channel = SomeGrpcClient::getDefaultChannel($host, [
    'credentials' => ChannelCredentials::createInsecure(),
]);
$openTracingInterceptor = new ClientInterceptor($tracer);
$interceptor = new InterceptorChannel($channel, $openTracingInterceptor);

$rootSpan = $tracer->startSpan("rootSpan");

$client = new SomeGrpcClient($host, [], $interceptor);
$args = new SomeGrpcMethodArgs();
$options = [
    'child_of' => $rootSpan
];
$request = $client->SomeGrpcMethodCall($args, [], $options);

/** @var $result GrpcCallResponse */
[$result, $code] = $request->wait();
echo $result->getPayload();

$rootSpan->finish();
$tracer->flush();
