Functions ¶
func EnvFromContext ¶
EnvFromContext returns the environment variables for the context. Service and sampling priority are included when set on the context so child processes can inherit them via StartSpanFromEnv.
func SetSamplingRate ¶ added in v0.66.0
SetSamplingRate sets the sampling rate for a given span name. The rate must be between 0 and 1.
func WithSamplingPriority ¶
WithSamplingPriority sets the sampling priority on the context. Spans created from this context (and child contexts) inherit the priority unless overridden by another WithSamplingPriority call. When unset, a default of 2 (FORCE_KEEP) is stamped at flush.
func WithService ¶
WithService sets the service name on the context. Spans created from this context (and child contexts) inherit the service unless overridden by another WithService call.
func WrapRoundTripper ¶
func WrapRoundTripper(rt http.RoundTripper) http.RoundTripper
WrapRoundTripper wraps the round tripper with the telemetry round tripper.
Types ¶
type LogMessage ¶
LogMessage defines the log message object
type LogPayload ¶
type LogPayload struct {
Logs []LogMessage `json:"logs"`
}
LogPayload defines the log payload object
type Span ¶
type Span struct {
// contains filtered or unexported fields
}
Span represents a span.
func SpanFromContext ¶
SpanFromContext returns the span from the context if available.
func StartSpanFromContext ¶
StartSpanFromContext starts a span using the context to find the parent span.
func StartSpanFromEnv ¶
StartSpanFromEnv starts a span using the environment variables to find the parent span. It also reads DATADOG_SERVICE and DATADOG_SAMPLING_PRIORITY from the environment and applies them to the context so the created span (and its children) inherit them.
func StartSpanFromIDs ¶
func StartSpanFromIDs(ctx context.Context, operationName, traceID, parentID string) (*Span, context.Context)
StartSpanFromIDs starts a span using the trace and parent IDs provided as decimal strings. Malformed inputs yield a fresh top-level trace.
func StartSpanFromUint64IDs ¶
func StartSpanFromUint64IDs(ctx context.Context, operationName string, traceID, parentID uint64) (*Span, context.Context)
StartSpanFromUint64IDs starts a span using the trace and parent IDs provided as uint64. The created span is marked top-level: it is the entry point of this process's participation in the trace.
func (*Span) SetResourceName ¶
SetResourceName sets the resource name of the span.
func (*Span) SetTopLevel ¶
func (s *Span) SetTopLevel()
SetTopLevel sets the span as a top level span.
type Telemetry ¶
type Telemetry struct {
// contains filtered or unexported fields
}
Telemetry handles the telemetry for fleet components.
func NewTelemetry ¶
NewTelemetry creates a new telemetry instance
type TracedCmd ¶ added in v0.67.0
TracedCmd is a wrapper around exec.Cmd that adds telemetry
func CommandContext ¶ added in v0.67.0
CommandContext runs a command using exec.CommandContext and adds telemetry
