Overview

Datadog tracing

Defined Under Namespace

Modules: Analytics, ClientIp, Component, Configuration, Contrib, Correlation, Diagnostics, Distributed, Events, Flush, MeasuredBuffer, Metadata, Pipeline, Remote, Runtime, Sampling, Transport, Utils, Workers Classes: CRubyTraceBuffer, Context, DefaultContextProvider, Event, FiberLocalContext, Span, SpanEvent, SpanLink, SpanOperation, SyncWriter, ThreadSafeTraceBuffer, TraceDigest, TraceOperation, TraceSegment, Tracer, Writer

Constant Summary collapse

TraceBuffer =

Trace buffer that stores application traces. The buffer has a maximum size and when the buffer is full, a random trace is discarded. This class is thread-safe and is used automatically by the Tracer instance when a Span is finished.

We choose the default TraceBuffer implementation for current platform dynamically here.

TODO We should restructure this module, so that classes are not declared at top-level ::Datadog. TODO Making such a change is potentially breaking for users manually configuring the tracer.

Class Attribute Details

.logger ⇒ Object (readonly)

The tracer’s internal logger instance. All tracing log output is handled by this object.

The logger can be configured through configure, through Core::Configuration::Settings::DSL::Logger options.

Class Method Details

.active_span ⇒ Object

The active, unfinished span, representing the currently instrumented application section.

The active span belongs to an active_trace.

Parameters:

  • Thread

    key Thread to retrieve trace from. Defaults to current thread. For internal use only.

Returns:

  • Datadog::Tracing::SpanOperation

    the active span

  • nil

    if no trace is active, and thus no span is active

def active_span
  current_tracer = tracer
  return unless current_tracer

  current_tracer.active_span
end

.active_trace ⇒ Object

The active, unfinished trace, representing the current instrumentation context.

The active trace is fiber-local.

Parameters:

  • Thread

    key Thread to retrieve trace from. Defaults to current thread. For internal use only.

Returns:

  • Datadog::Tracing::TraceSegment

    the active trace

  • nil

    if no trace is active

  return unless current_tracer

  current_tracer.active_trace
end

.baggage ⇒ Datadog::Tracing::Distributed::Baggage

Returns the baggage for the current trace.

If there is no active trace, a new one is created.

Returns:

  • The baggage for the current trace.

def baggage
  # Baggage should not be dependent on there being an active trace.
  # So we create a new TraceOperation if there isn't one.
  active_trace = self.active_trace || tracer.continue_trace!(nil)
  active_trace.baggage ||= {}
  active_trace.baggage
end

.before_flush(*processors) ⇒ Object .before_flush {|trace| ... } ⇒ Object

Overloads:

  • .before_flush(*processors) ⇒ Object

    Parameters:

    • Array<Datadog::Tracing::Pipeline::SpanProcessor>

      processors a list of processors that can modify

      or filter the trace.

    • Array<#call(Datadog::Tracing::TraceSegment)>

      processors a list of callable objects that receive a

      TraceSegment and can modify or filter the trace.

  • .before_flush {|trace| ... } ⇒ Object

    Yields:

    • Receive a TraceSegment and can modify or filter the trace.

    Yield Parameters:

    Yield Returns:

    • (Datadog::Tracing::TraceSegment) —

      the trace object that will be passed to the next processor. Normally the same trace parameter object should be returned.

  Pipeline.before_flush(*processors, &processor_block)
end

.continue_trace!(digest) { ... } ⇒ Object

Setup a new trace execution context to continue from where another trace left off. This is useful to continue distributed or async traces.

The first span created in the restored context is a direct child of the active span from when the TraceDigest was created.

When no block is given, the trace context is restored in the current thread. It remains active until the first span created in this restored context is finished. After that, if a new span is created, it start a new, unrelated trace.

When a block is given, the trace context is restored inside the block execution. It remains active until the block ends, even when the first span created inside the block finishes. This means that multiple spans can be direct children of the active span from when the TraceDigest was created.

Parameters:

  • Datadog::Tracing::TraceDigest

    digest continue from the TraceDigest.

  • Thread

    key Thread to retrieve trace from. Defaults to current thread. For internal use only.

Yields:

  • Optional block where this #continue_trace! digest scope is active. If no block, the digest remains active after #continue_trace! returns.

Returns:

  • Object

    If a block is provided, the result of the block execution.

  • Datadog::Tracing::TraceOperation

    If no block, the active TraceOperation.

def continue_trace!(digest, &block)
  tracer.continue_trace!(digest, &block)
end

.correlation ⇒ Object

Information about the currently active trace.

The most common use cases are tagging log messages and metrics.

Parameters:

  • Thread

    key Thread to retrieve trace from. Defaults to current thread. For internal use only.

Returns:

  • Datadog::Tracing::Correlation::Identifier

    correlation object

def correlation
  # We access this in this way as:
  # * If the components have not been initialized, it doesn't make sense to initialize datadog just to say
  #   'nil' here
  # * It prevents recursive initialization attempts, see https://github.com/DataDog/dd-trace-rb/issues/3385
  components = Datadog.send(:components, allow_initialization: false)
  current_tracer = components.tracer if components

  return Datadog::Tracing::Correlation::Identifier.new unless current_tracer

  current_tracer.active_correlation
end

.enabled? ⇒ Boolean

Is the tracer collecting telemetry data in this process?

Returns:

  • true if the tracer is collecting data in this process, otherwise false.

# File 'lib/datadog/tracing.rb', line 167

def enabled?
  current_tracer = tracer
  return false unless current_tracer

  current_tracer.enabled
end

.keep! ⇒ Object

If an active trace is present, forces it to be retained by the Datadog backend.

Any sampling logic will not be able to change this decision.

If no trace is active, no action is taken.

Returns:

  • void

# File 'lib/datadog/tracing.rb', line 82

def keep!
  trace = active_trace
  trace&.keep!
end

.log_correlation ⇒ String

Textual representation of correlation, which can be added to individual log lines in order to correlate them with the active trace.

Example:

“‘ MyLogger.log(“#log_correlation] My message”) # dd.env=prod dd.service=auth dd.version=13.8 dd.trace_id=5458478252992251 dd.span_id=7117552347370098 My message “`

Returns:

  • correlation information; or an empty String if Tracing is disabled (‘!enabled?`)

# File 'lib/datadog/tracing.rb', line 123

def log_correlation
  return '' unless enabled?

  correlation.to_log_format
end

.reject! ⇒ Object

If an active trace is present, forces it to be dropped and not stored by the Datadog backend.

Any sampling logic will not be able to change this decision.

If no trace is active, no action is taken.

Returns:

  • void

# File 'lib/datadog/tracing.rb', line 90

def reject!
  trace = active_trace
  trace&.reject!
end

.shutdown! ⇒ Object

Gracefully shuts down the tracer.

The public tracing API will still respond to method calls as usual but might not internally perform the expected internal work after shutdown.

This avoids errors being raised across the host application during shutdown while allowing for the graceful decommission of resources.

shutdown! cannot be reversed.

# File 'lib/datadog/tracing.rb', line 153

def shutdown!
  current_tracer = tracer
  return unless current_tracer

  current_tracer.shutdown!
end

.trace(name, continue_from: nil, on_error: nil, resource: nil, service: nil, start_time: nil, tags: nil, type: nil, id: nil) {|span_op, trace_op| ... } ⇒ Object

Return a span_op and trace_op that will trace an operation called name.

You could trace your code using a do-block like:

“‘ tracer.trace(’web.request’) do |span_op, trace_op|

span_op.service = 'my-web-site'
span_op.resource = '/'
span_op.set_tag('http.method', request.request_method)
do_something()

end “‘

The #trace method can also be used without a block in this way: “‘ span_op = tracer.trace(’web.request’, service: ‘my-web-site’) do_something() span_op.finish() “‘

Remember that in this case, calling Datadog::Tracing::SpanOperation#finish is mandatory.

When a Trace is started, #trace will store the created span; subsequent spans will become its children and will inherit some properties: “‘ parent = tracer.trace(’parent’) # has no parent span child = tracer.trace(‘child’) # is a child of ‘parent’ child.finish() parent.finish() parent2 = tracer.trace(‘parent2’) # has no parent span parent2.finish() “‘

Parameters:

  • String

    name Span operation name.

    See / Primary Operations in Services.

  • Datadog::Tracing::TraceDigest

    continue_from continue a trace from a TraceDigest.

    Used for linking traces that are executed asynchronously.

  • Proc

    on_error a block that overrides error handling behavior for this operation.

  • String

    resource the resource this span refers, or name if it’s missing

  • String

    service the service name for this span.

  • Time

    start_time time which the span should have started.

  • Hash<String,String>

    tags extra tags which should be added to the span.

  • String

    type the type of the span. See Datadog::Tracing::Metadata::Ext::AppTypes.

  • Integer

    the id of the new span.

Yields:

  • Optional block where new newly created SpanOperation captures the execution.

Yield Parameters:

Returns:

  • Object

    If a block is provided, returns the result of the block execution.

  • Datadog::Tracing::SpanOperation

    If no block is provided, returns the active,

    unfinished SpanOperation.
