Warning

OpenCensus and OpenTracing have merged to form OpenTelemetry, which serves as the next major version of OpenCensus and OpenTracing.

OpenTelemetry has now reached feature parity with OpenCensus, with tracing and metrics SDKs available in .NET, Golang, Java, NodeJS, and Python. All OpenCensus Github repositories, except census-instrumentation/opencensus-python, will be archived on July 31st, 2023. We encourage users to migrate to OpenTelemetry by this date.

To help you gradually migrate your instrumentation to OpenTelemetry, bridges are available in Java, Go, Python, and JS. Read the full blog post to learn more.

OpenCensus Zipkin Exporter for PHP

This library provides an ExporterInterface for exporting Trace data to a Zipkin instance.

Installation & basic usage

Install the opencensus/opencensus-exporter-zipkin package using composer:
```
$ composer require opencensus/opencensus-exporter-zipkin:~0.1
```

Initialize a tracer for your application:

use OpenCensus\Trace\Tracer;
use OpenCensus\Trace\Exporter\ZipkinExporter;

Tracer::start(new ZipkinExporter('my-service-name'));

Customization

Configuring the Zipkin endpoint

You may provide an optional initialization parameter for the Zipkin endpoint. This value should be a full URL to the v2 spans endpoint.

$exporter = new ZipkinExporter('my-service-name', 'http://example.com:9411/api/v2/spans');

Configuring the local IPv4 or IPv6 address

Zipkin allows you to optionally specify the host IP address of the server that is handling the traced requests.

For IPv4:

// gethostbyname may make a DNS query, so you may want to cache this
$ipv4 = gethostbyname(gethostname());
$exporter->setLocalIpv4($ipv4);

Similarly, you may set the local IPv6 address if you can obtain it:

$exporter->setLocalIpv6($ipv6);
