Current ways to expose metrics, logs from frontend

[pascalbe-dev]

Hey guys, I love the idea behind open telemetry to one standardized way to collect telemetry data from different kinds of applications.

If I see it correctly, opentelemetry js does not yet provide ways to auto instrument frontend applications to expose metrics or ways to extract logs to a central log management tool like graylog.

In the end, I would like to use the same tool for backend and frontend to dig into the logs or visualize my metrics.
What do you guys currently use to get log, metric data centralized? I see a lot of Prometheus/Grafana for metrics and stuff like Graylog for logs, but does this also work with frontend apps?
I've come across Sentry, but it seems to be quite to huge to run on premise and its not so popular for backend metrics, logs, tracing. At least that's my perception.

I would be great to have a small discussion here about libs and tools, which people successfully use in the frontend and ideally also in the backend.
