[FEATURE REQUEST] Access logs

[cidious]

The problem is I can't find the access logs when running RR as a frontend web server for PHP Laravel app.

When running the app as Nginx+PHP-FPM you got the access logs from nginx plus slow logs from FPM. Both of them can be routed to stderr inside a container and caught for analysis.

I see the two options to get the logs using RR:

• run RR in debug mode. You got a lot more logging than the access logs. It can affect the performance.
• create the logs with Laravel logger. It should affect the performance plus increase the TTFB (time to first byte) lowering the server responsiveness. Plus it cannot log the static files.

Is it possible to output the access logs by RR in production env?

Hey @cidious. You can set the log level to a different than the debug mode. Have you tried the other options: https://github.com/spiral/roadrunner-binary/blob/master/.rr.yaml#L66 ?

@rustatian thanks for the answer. I can't find any access logs in any log level except the debug one. Tried info, warn, error, panic -- no result. Even the debug level doesn't have such data as Referer or User-agent and I can't find the option to turn it on.

# rr -v
rr version 2.3.3 (build time: 2021-07-14T15:28:46+0000, go1.16.6)

@cidious Ok, thanks. Could you please give me the link with the list of entities that should be logged (some documentation)? And I'll try to cover these places. Also, debug logs will slow down your app, but not much (except you have a low-latency system with high RPS (more than 10k RPS)). At the moment you can use production mode with the debug level.

@rustatian The best log format for production is JSON. Sample nginx usage: [1] [2] Official documentation: [link]

As for me, I need the fields: remote_addr, http_host, request, time_local, request_length, request_time, status, bytes_sent, http_user_agent, http_referer

Also it would be nice if RR could collect the slow logs like PHP-FPM does: [1] [2] I'm not sure if it's possible to output the PHP backtrace, but it would be really useful feature.

Great, thanks @cidious. I'll add these log fields as info (default production loglevel). I'll also discuss this feature with our PHP team and return back to you soon 😃

@cidious Feature accepted and planned for the current sprint https://github.com/orgs/spiral/projects/2.

@cidious Feature will be available by the end of the week in the v2.5.0-beta.2 with the following fields: method - http method. remote_addr - request remote address. bytes_sent - content-length, http_host - host. request - request Query. time_local - local time in Common Log Format. request_length - request body with headers size (content-len + size of all headers) in bytes. Max allowed headers size for the RR is 1MB. request_time - request processing time in seconds with a milliseconds resolution. status - http response status. http_user_agent - http user agent http_referer - http referer

@cidious Please, test the v2.5.0-beta.2: https://github.com/spiral/roadrunner-binary/releases/tag/v2.5.0-beta.2
