Struct TelemetryLayer 

pub struct TelemetryLayer {
    pub inner_layer: Layer<Registry, DefaultFields, TelemetryFormatter, NonBlocking>,
}

A tracing Layer to generate telemetry to be later consumed into InfluxDB

This tracing Layer formats telemetry and stores the output in a known location ($FUEL_HOME/tmp/.telemetry), ready for ingestion by an InfluxDB collector.

Fields

inner_layer: Layer<Registry, DefaultFields, TelemetryFormatter, NonBlocking>

Implementations

impl TelemetryLayer

pub fn __new() -> Result<(Self, WorkerGuard)>

Although public, __new() is only intended to be called via the following constructor macros:

• fuel_telemetry::new!()
• fuel_telemetry::new_with_watchers!()
• fuel_telemetry::new_with_watchers_and_init!()

Trait Implementations

impl Layer<Registry> for TelemetryLayer

fn on_close(&self, id: Id, ctx: Context<'_, Registry>)

Notifies this layer that the span with the given ID has been closed.

fn on_enter(&self, id: &Id, ctx: Context<'_, Registry>)

Notifies this layer that a span with the given ID was entered.

fn on_event(&self, event: &Event<'_>, ctx: Context<'_, Registry>)

Notifies this layer that an event has occurred.

fn on_exit(&self, id: &Id, ctx: Context<'_, Registry>)

Notifies this layer that the span with the given ID was exited.

fn on_id_change(&self, old: &Id, new: &Id, ctx: Context<'_, Registry>)

Notifies this layer that a span ID has been cloned, and that the subscriber returned a different ID.

fn on_new_span( &self, attrs: &Attributes<'_>, id: &Id, ctx: Context<'_, Registry>, )

Notifies this layer that a new span was constructed with the given Attributes and Id.

fn on_follows_from(&self, span: &Id, follows: &Id, ctx: Context<'_, Registry>)

Notifies this layer that a span with the ID span recorded that it follows from the span with the ID follows.

fn on_record(&self, span: &Id, values: &Record<'_>, ctx: Context<'_, Registry>)

Notifies this layer that a span with the given Id recorded the given values.

fn on_register_dispatch(&self, subscriber: &Dispatch)

Performs late initialization when installing this layer as a Subscriber.

fn on_layer(&mut self, subscriber: &mut S)

Performs late initialization when attaching a Layer to a Subscriber.

fn register_callsite(&self, metadata: &'static Metadata<'static>) -> Interest

Registers a new callsite with this layer, returning whether or not the layer is interested in being notified about the callsite, similarly to Subscriber::register_callsite.

fn enabled(&self, metadata: &Metadata<'_>, ctx: Context<'_, S>) -> bool

Returns true if this layer is interested in a span or event with the given metadata in the current Context, similarly to Subscriber::enabled.

fn event_enabled(&self, _event: &Event<'_>, _ctx: Context<'_, S>) -> bool

Called before on_event, to determine if on_event should be called.

fn and_then<L>(self, layer: L) -> Layered<L, Self, S>

where L: Layer<S>, Self: Sized,

Composes this layer around the given Layer, returning a Layered struct implementing Layer.

fn with_subscriber(self, inner: S) -> Layered<Self, S>

where Self: Sized,

Composes this Layer with the given Subscriber, returning a Layered struct that implements Subscriber.

fn with_filter<F>(self, filter: F) -> Filtered<Self, F, S>

where Self: Sized, F: Filter<S>,

Combines self with a Filter, returning a Filtered layer.

fn boxed(self) -> Box<dyn Layer<S> + Sync + Send>

where Self: Sized + Layer<S> + Send + Sync + 'static, S: Subscriber,

Erases the type of this Layer, returning a Boxed dyn Layer trait object.
