[RFC] Observability component(s)

[mateuszsip]

Description

Hi! I believe PHP ecosystem needs proper observability components and Symfony could be a driver to spread some awareness and expertise on that topic. This is a key part of microservices architecture and lack of proper tooling is painful in PHP apps.

The goal would be to implement metrics and tracing easier - to create some common abstraction for various services and standards and then easily integrate it into the Symfony app.

Initiatives like https://opentelemetry.io can help us to shape the ground up

What do you think about that? I couldn't find any dedicated discussion around it.

@mateuszsip Did you try https://github.com/worldia/instrumentation-bundle ?

IMHO it souds to be a great idea to have a component/bundle in the symfony eco system with the functionallity. Having metrics (for Prometheus) of the application and sth like a health endpoint are features a couple of symfony applications will need stuff like that. The mentioned instrumentation-bundle seems to have a lot of functionallity for that. But i think monitoring becomes more important. From my POV it could be a great idea to add the functionallity. A bit like a lightweight "Spring Boot Actuator" in java.

Hi there! If you are interested, there's a proposal for a Tracing PSR: https://github.com/php-fig/fig-standards/blob/master/proposed/tracing-meta.md

We are discussing it on the PHP-FIG discord, and here you can find the current state of the proposal. It will be interesting for us to have yours contribution too!

Thanks for the hint @alekitto! Seems to be a good proposal for the system tracing.

But this RFC is not only about tracing: More details about this topic here: https://peter.bourgon.org/blog/2017/02/21/metrics-tracing-and-logging.html this image is as well from the blogpost.

Tracing is only one part of the observability. Logging is implemented for now in the most systems. But tracing and monitoring becomes more popular.

But yes, it's always good to base it on a defined standard.

Hello @maxbeckers ,

Please consider adding a background to uploaded images, in order to improve accessibility. My dark-themed Github interface does not comply with dark pictures, cf this screenshot:

Thank you!
