Auto instrumented tracing demo's
This repo contains a couple of demo's based on the Angular Tour Of Heroes and the Symfony demo application. The goal of these demo's was not to test tracing itself, but to test auto-instrumenting libraries and how specific their traces are. This research was done during the first half of 2019 (as is apparent by the cherry-picked commits), when some solutions available now weren't.
Currently, there's three:
- Angular instrumented with Zipkin through angular-tracing
- Symfony instrumented with OpenCensus Symfony-integration
- Symfony instrumented with Zipkin through zipkin-instrumentation-symfony
Running
Collector
The demo's in this repo are set-up to send their spans to localhost:9411, i.e. a Zipkin endpoint. This however doesn't mean you necessarily have to use Zipkin, but just a collector that accepts spans in the format.
Angular-zipkin
Install the necessary modules with yarn install, then run the demo with yarn start.
Symfony-opencensus
Install the necessary dependencies with composer install, then run the demo with php bin/console server:run
This specific demo also has an option to use the OpenCensus PHP extension. It is however adviced to build the plugin from source, since the pecl-version gave some problems during my own testing.
The usage of the plugin can be disabled by commenting out the Symfony::load(); command in src/Opencensus/OpenCensusBundle.php
Symfony-zipkin
Install the necessary dependencies with composer install, then run the demo with php bin/console server:run
