Set the log level of run command

[eratio08]

Hello, I'm new to using quickwit. I was wondering how I can set the log level of the quickwit service running in the Docker container? I could not find any information in the docs and searching the code I only found

quickwit/quickwit/quickwit-cli/src/main.rs

Line 66 in 7458bbf

setup_logging_and_tracing(command.default_log_level(), ansi_colors, build_info)?;

which seems to always pick the default log level of info.

Is there any way to set the log level of the run command?

you can set the environment variable RUST_LOG, for instance in a shell you can run RUST_LOG=debug quickwit run (there are multiple ways to set environment variable depending on how you start your containers).
You can read more on what value you can put to get more precise control on this page.
I'm surprised we don't mention RUST_LOG anywhere in the documentation. We definitely should. I'll open a ticket for that (edit: #4378)

[eratio08]

Will try to get a sample of these logs. So it's definitely part of the container as it's local to the container logs of quickwit.

The orchestration I'm using is docker compose so there is no special logging injected by the compose orchestration.

This is the regular output of the container. It happens very frequently.

@eratio08 Which tag are you using? This is supposed to happen only on qw-fulmicoton.

[eratio08]

Actually I was not using any tag so pretty random I guess, I thing it defaults to latest, which will be random if it's not deliberately set. Which tag is recommended here? https://quickwit.io/docs/get-started/quickstart#use-quickwits-docker-image does not seem to name any.

Let me check which I've pulled 🔍

[eratio08]

I've pulled

quickwit/quickwit latest sha256:3e7d718c1104d058e29dc0f6e5c84facc3d993523deb9a7058be3b25392ef18f   aac8163a6ec0   7 days ago      292MB

I'm assuming using 0.7.0 would be proper.

Hi all,
i am trying to instrument my application with open telemetry, i am trying to send my traces to quick wit. i have installed quick wit in cluster

func InitTracer() (*sdktrace.TracerProvider, error) {
    ctx := context.Background()

    headers := map[string]string{
        "service-name": "myapp",
    }

    client := otlptracegrpc.NewClient(
        otlptracegrpc.WithEndpoint("quickwit cluster installed url:port"),
        otlptracegrpc.WithHeaders(headers),
        otlptracegrpc.WithInsecure(),
    )

    exporter, err := otlptrace.New(ctx, client)
    if err != nil {
        log.Fatalf("failed to initialize exporter: %e", err)
    }

    res, err := resource.New(
        ctx,
        resource.WithAttributes(
            attribute.String("service.name", "myapp"),
            attribute.String("library.language", "go"),
        ),
    )
    if err != nil {
        log.Fatalf("failed to initialize resource: %e", err)
    }

    // Create the trace provider
    tp := sdktrace.NewTracerProvider(
        trace.WithSampler(trace.AlwaysSample()),
        sdktrace.WithBatcher(exporter),
        sdktrace.WithResource(res),
    )

    // Set the global trace provider
    otel.SetTracerProvider(tp)

    // Set the propagator
    propagator := propagation.NewCompositeTextMapPropagator(propagation.TraceContext{}, propagation.Baggage{})
    otel.SetTextMapPropagator(propagator)

    return tp, nil
}

but i am getting below error
[GIN] 2024/01/17 - 11:07:53 | 200 | 487.21µs | ::1 | GET "/books"
2024/01/17 11:07:58 traces export: rpc error: code = Unimplemented desc = unexpected HTTP status code received from server: 404 (Not Found); transport: received unexpected content-type "text/plain; charset=utf-8"

[trinity-1686a]

can you open a separate discussion? This doesn't seem related to setting Quickwit log level

[fmassot]

@eratio08 which docker image are you using? having those logs is not normal

[fulmicoton]

This is from my tag qw-fulmicoton. I assume @eratio08 got it by pulling the :latest tag

[eratio08]

Yep was the latest tag which might have randomly selected that image if it was published as the most recent during that time.
