LGTM! Do you think is worth documenting the new options? (we tend to keep some very internal options as undocumented)

I considered these options same as the other ones (such as ExportTimeout) so I guess once we document those, we could also document these ones. Wdyt?

Grafana and other products for the company are now a joke relative how the documentation is managed. The result of the documentation quality is the fact that installing and working with the product is a challenge. Of course the results are beautiful, but man, sometimes it is too hard and too much time to spend on it. Just spend few minutes on the Grafana Community and you will understand. For me you are stuck in the developper mindset and don't understand the difficulties from a user point of view.

So @renaudrenaud would you consider that a "debugging parameters" section in our documentation would be helpful for you?

Mario, thanks a lot for what you have done, but let me explain this.
I've installed version 1.5.3 and the traces produced are all about html.
2024-05-20 04:30:51.52043051 (39.584061ms[39.584061ms]) SRV 302 POST /arc/arc_check [::1 as localhost]->[::1 as java:11080] size:1490B svc=[java java] traceparent=[]
2024-05-20 04:30:52.52043052 (49.802118ms[49.802118ms]) SRV 200 GET /arc/secure/arc.htm [::1 as java]->[::1 as java:11080] size:1121B svc=[java java] traceparent=[00-873fe64e8846010751b733185fb97aa0-0000000000000000-01]
...
Then 2 weeks later on the same vm with the same configuration but v1.6.1 the traces are all about SQL.
2024-05-27 10:51:27.527105127 (7.268µs[7.268µs]) SQL 0 SELECT [127.0.0.1 as java]->[127.0.0.1 as java:5432] size:0B svc=[java java] traceparent=[]

2024-05-27 10:51:27.527105127 (2.56401ms[2.56401ms]) SQL 0 SELECT [127.0.0.1 as java]->[127.0.0.1 as java:5432] size:0B svc=[java java] traceparent=[]
I would like to understand why. Is there any swith / parameter I did not found in the documentation?

@renaudrenaud thanks for your feedback and suggestions, highly appreciated but:

• Keep a respectful tone, please
• Open a separate discussion/issue instead derailing the conversation in a different issue/PR

thanks

[mariomac]

@renaudrenaud that sounds like a bug. Would you mind filing an issue and provide some details about your setup and instrumented applications? https://github.com/grafana/beyla/issues

Your products are great but their doc generate a lot of frustration. Thanks.
