Hi pecl-dev, TL;DR: stackdriver_trace extension (which wasn't published yet) will be released as opencensus.
Previously, I had applied for membership to publish an extension called stackdriver_trace which allows easy tracing of PHP applications by watching for function/method invocations. Instead, it will be released as part of the OpenCensus project. This is a cross-language, open source effort to provide common tools for application developers to add metrics tracking and distributed tracing to their applications. The goal is that the instrumentation of your app should happen once and you can choose where to send your data with a swappable reporter interface. The functionality remains the same. As such, the extension and accompanying PHP library will be named OpenCensus. If you have any concerns, let me know. Thanks, Jeff Ching
