tracing-elastic-apm's Issues

Error: relative URL without a base with example configuration

I am trying this library with the example code from readme.md file, anyway, it keeps printing this error at runtime:

ERROR tracing_elastic_apm::apm_client: Error sending batch to APM! error=builder error: relative URL without a base

My Code:

    let apm_layer = tracing_elastic_apm::new_layer(
        "ServiceName".to_string(),
        tracing_elastic_apm::config::Config::new("127.0.0.1:8200".to_string())
    );

    let subscriber = tracing_subscriber::registry()
        .with(apm_layer);

I am using version 2.1

Infinite loop?

Hey there,

seems like I'm to dump to configure the lib properly. For me it seems like there is an infinite loop as the ApmClient is sending a network request for closed spans and hyper is opening new spans for each network request. Is it only me observing this? I also would like to see in the readme an example which integrates with the formatter example from the tracing lib.

Here is my dump code

#[tracing::instrument]
pub async fn run_traced_test_task() {
    info!("Some task");
    thread::sleep(Duration::from_secs(10));
    info!("Another log");
}

#[tokio::main]
async fn main() {
    let apm_layer = tracing_elastic_apm::new_layer(
        "monitor-helper".to_string(),
        Config::new("http://127.0.0.1:8200".to_string()),
    )
    .expect("APM Layer to be created");

    tracing_subscriber::registry().with(apm_layer).init();

    info!("Started!");

    let handle = tokio::spawn(async {
        std::thread::sleep(Duration::from_secs(5));
        run_traced_test_task().await;
    });

    tokio::try_join!(handle).unwrap();

    std::thread::sleep(Duration::from_secs(5));
    info!("Goodbye");
}

Formatting Incorrect in apm

I am currently using layers in my subscriber from this crate and fmt::Layer::default(). But noticed that the transactions only show on elastic apm as "HTTP Request" rather than something like "POST /route", additionally there is no http meta data shown on the transaction. Do I need to add another layer to format the trace correctly for apm? If so, what layer should I be including?

Is there any way to update the name of the outer transaction span at the end of a request?

Using axum I have a very early middleware that attaches a span with a propegated request id from a header.

          let span = info_span!("request", %request_id);
          next.run(req).instrument(span).await

Since this is the first outermost span it becomes the Transaction for elastic APM, so it shows up as simply request in the UI for Elastic Observability.

From Elastic examples it seems usually these out transaction spans are annotated as HTTP 5xx POST /service/endpoint but much of that information is not known unitl after next.run(req).instrument(span).await has run.

Is there any way to update the transaction name?

I was about to try something like the following

            let span = info_span!("request", %request_id);
            let _enter = span.enter();
            let res = next.run(req).in_current_span().await;
            if let Some(id) = span.id() {
                let mut extensions = req.extensions_mut();
                if let Some(mut transaction) = extensions.get_mut::<tracing_elastic_apm::model::Transaction>() {
                    transaction.name= Some(.../*rest of logic here*/);
                }
            };
            res
 ``

but since Transaction is not `pub` outside the `tracing_elastic_apm` crate a gave up fairly quickly.
Any thoughts?

tracing-elastic-apm does not work without a global subscriber

The tracing-elastic-apm layer does nothing if used with a default subscriber. E.g.:

let stdout_layer = ...;
let another_layer = ...;
let another_another_layer = ...;

let tracing_elastic_apm_layer = tracing_elastic_apm::new_layer(
    "ServiceName".to_string(),
    tracing_elastic_apm::Config::new("APM address".to_string())
)?;

// The order of registration of the layers has no impact on this bug
    let subscriber = tracing_subscriber::registry()
        .with(stdout_layer)
        .with(another_layer)
        .with(another_another_layer)
        .with(tracing_elastic_apm_layer);

// Using a default subscriber all layers work as expected except 
// the tracing_elastic_apm_layer that does NOT work at all
let _guard = tracing::subscriber::set_default(subscriber);

// It works as expected if we use a global subscriber instead:
// tracing::subscriber::set_global_default(subscriber).unwrap()

Any idea why?

Errors in send_batch() will cause infinite errors to be logged

I accidentally messed up the destination URL when initializing my tracing_elastic_apm layer and my console was flooded with an infinite stream of logs:

Failed to create shared memory: Too many open files
Failed to create shared memory: Too many open files
2022-06-30T11:22:26.457546Z ERROR tracing_elastic_apm::apm_client: Error sending batch to APM! error=error sending request for url (http://localhost:9200/intake/v2/events): error trying to connect: tcp open error: Too many open files (os error 24)
2022-06-30T11:22:26.457532Z ERROR tracing_elastic_apm::apm_client: Error sending batch to APM! error=error sending request for url (http://localhost:9200/intake/v2/events): error trying to connect: tcp open error: Too many open files (os error 24)
Failed to create shared memory: Too many open files

After some digging, it appears that whenever ApmClient::send_batch() fails it will log the error... which in turn triggers another call to send_batch(), which also errors out, ad infinitum. This is the line responsible:

tracing-elastic-apm/src/apm_client.rs

Line 122 in ab21a65

error!(error = %error, "Error sending batch to APM!");

Do we need to log errors that occurred when posting messages upstream, or would it be okay to fail silently?

I'm guessing the "Too many open files" part of the error message is just because we keep trying to connect to the same port and run out of file descriptors, so it's just a symptom of this infinite logging problem.

Random Mutex poisoned Error

Bug Report

Description

After upgrading to tracing-elastic-apm 3.2 we are experiencing random PoisonError:

thread 'main' panicked at 'Mutex poisoned: PoisonError { .. }', /home/ufo/.cargo/registry/src/github.com-1ecc6299db9ec823/tracing-subscriber-0.3.2/src/registry/sharded.rs:433:58

As you can see below, the tracing-elastic-apm crate is in the full panic stacktrace (at line 19), so, it could be the cause of it.
We don't have this error when tracing-elastic-apm is not used.

Authorization header for ApiKey authentication is wrongly formatted

Bug description

It is not possible to authenticate to the APM Server via ApiKey.

Details

The HTTP Authorization header for authenticating via ApiKey should be in the form:
Authorization: ApiKey <base64_encoded_credentials
see: Elastic documentation (I could not find APM Server specific doc for the ApiKey authentication).

Here instead the ApiKey identifier is also base64 encoded. So the authentication does not work.

tracing-elastic-apm/src/apm_client.rs

Line 75 in 7634b12

base64::encode(format!("ApiKey {}:{}", key.id, key.key))

No event are reported except for `ERROR`

I tried to instrument my code and use this library. I was not able to make it works until I started looking directly into the code of the library and stumble on that line.

It happens that the code I was running was never reporting on ERROR level. I'm wondering why only ERROR events are reported and not the other type of Level. Or maybe I missed something else?
