Any support requests, bug reports, or development contributions should be directed to that project. A distributed tracing system for Google Cloud Platform that collects latency data from App Engine applications and displays it in near real time in the Google Cloud Platform Console. ### Installation [](#installation) To begin, install the preferred dependency manager for PHP, [Composer](https://getcomposer.org/). Now install this component: ``` $ composer require google/cloud-trace ``` This component supports both REST over HTTP/1.1 and gRPC. In order to take advantage of the benefits offered by gRPC (such as streaming methods) please see our [gRPC installation guide](https://cloud.google.com/php/grpc). ### Authentication [](#authentication) Please see our [Authentication guide](https://github.com/googleapis/google-cloud-php/blob/main/AUTHENTICATION.md)for more information on authenticating your client. Once authenticated, you'll be ready to start making requests. ### Sample [](#sample) ``` use Google\ApiCore\ApiException; use Google\Cloud\Trace\V2\Client\TraceServiceClient; use Google\Cloud\Trace\V2\Span; use Google\Cloud\Trace\V2\TruncatableString; use Google\Protobuf\Timestamp; // Create a client. $traceServiceClient = new TraceServiceClient(); // Prepare the request message. $displayName = new TruncatableString(); $startTime = new Timestamp(); $endTime = new Timestamp(); $request = (new Span()) ->setName($name) ->setSpanId($spanId) ->setDisplayName($displayName) ->setStartTime($startTime) ->setEndTime($endTime); // Call the API and handle any network failures. try { /** @var Span $response */ $response = $traceServiceClient->createSpan($request); printf('Response data: %s' . PHP_EOL, $response->serializeToJsonString()); } catch (ApiException $ex) { printf('Call failed with message: %s' . PHP_EOL, $ex->getMessage()); } ``` See the [OpenCensus documentation](https://github.com/census-instrumentation/opencensus-php) for more configuration options and features. ### Debugging [](#debugging) Please see our [Debugging guide](https://github.com/googleapis/google-cloud-php/blob/main/DEBUG.md)for more information about the debugging tools. ### Version [](#version) This component is considered GA (generally available). As such, it will not introduce backwards-incompatible changes in any minor or patch releases. We will address issues and requests with the highest priority. ### Next Steps [](#next-steps) 1. Understand the [official documentation](https://cloud.google.com/trace/docs/). 2. Take a look at [in-depth usage samples](https://github.com/GoogleCloudPlatform/php-docs-samples/tree/master/trace/). ### Health Score 67 — FairBetter than 100% of packages Maintenance83 Actively maintained with recent releases Popularity48 Moderate usage in the ecosystem Community35 Small or concentrated contributor base Maturity88 Battle-tested with a long release history Bus Factor3 3 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
