Tracing¶
Tracing architecture overview.
config.trace.v2.Tracing¶
[config.trace.v2.Tracing proto]
The tracing configuration specifies global settings for the HTTP tracer used by Envoy. The configuration is defined by the Bootstrap tracing field. Envoy may support other tracers in the future, but right now the HTTP tracer is the only one supported.
{
"http": "{...}"
}
- http
- (config.trace.v2.Tracing.Http) Provides configuration for the HTTP tracer.
config.trace.v2.Tracing.Http¶
[config.trace.v2.Tracing.Http proto]
{
"name": "...",
"config": "{...}",
"typed_config": "{...}"
}
- name
(string, REQUIRED) The name of the HTTP trace driver to instantiate. The name must match a supported HTTP trace driver. Built-in trace drivers:
- envoy.lightstep
- envoy.zipkin
- envoy.dynamic.ot
- envoy.tracers.datadog
- envoy.tracers.opencensus
- config
(Struct) Trace driver specific configuration which depends on the driver being instantiated. See the trace drivers for examples:
Only one of config, typed_config may be set.
- typed_config
(Any) Trace driver specific configuration which depends on the driver being instantiated. See the trace drivers for examples:
Only one of config, typed_config may be set.
config.trace.v2.LightstepConfig¶
[config.trace.v2.LightstepConfig proto]
Configuration for the LightStep tracer.
{
"collector_cluster": "...",
"access_token_file": "..."
}
- collector_cluster
- (string, REQUIRED) The cluster manager cluster that hosts the LightStep collectors.
config.trace.v2.ZipkinConfig¶
[config.trace.v2.ZipkinConfig proto]
{
"collector_cluster": "...",
"collector_endpoint": "...",
"trace_id_128bit": "...",
"shared_span_context": "{...}"
}
- collector_cluster
- (string, REQUIRED) The cluster manager cluster that hosts the Zipkin collectors. Note that the Zipkin cluster must be defined in the Bootstrap static cluster resources.
- collector_endpoint
- (string, REQUIRED) The API endpoint of the Zipkin service where the spans will be sent. When using a standard Zipkin installation, the API endpoint is typically /api/v1/spans, which is the default value.
- trace_id_128bit
- (bool) Determines whether a 128bit trace id will be used when creating a new trace instance. The default value is false, which will result in a 64 bit trace id being used.
config.trace.v2.DynamicOtConfig¶
[config.trace.v2.DynamicOtConfig proto]
DynamicOtConfig is used to dynamically load a tracer from a shared library that implements the OpenTracing dynamic loading API.
{
"library": "...",
"config": "{...}"
}
- library
- (string, REQUIRED) Dynamic library implementing the OpenTracing API.
- config
- (Struct) The configuration to use when creating a tracer from the given dynamic library.
config.trace.v2.DatadogConfig¶
[config.trace.v2.DatadogConfig proto]
Configuration for the Datadog tracer.
{
"collector_cluster": "...",
"service_name": "..."
}
- collector_cluster
- (string, REQUIRED) The cluster to use for submitting traces to the Datadog agent.
- service_name
- (string, REQUIRED) The name used for the service when traces are generated by envoy.
config.trace.v2.OpenCensusConfig¶
[config.trace.v2.OpenCensusConfig proto]
Configuration for the OpenCensus tracer.
Warning
This message type has experimental status.
{
"trace_config": "{...}",
"stdout_exporter_enabled": "...",
"stackdriver_exporter_enabled": "...",
"stackdriver_project_id": "...",
"zipkin_exporter_enabled": "...",
"zipkin_url": "...",
"zipkin_service_name": "...",
"incoming_trace_context": [],
"outgoing_trace_context": []
}
- trace_config
- (.opencensus.proto.trace.v1.TraceConfig) Configures tracing, e.g. the sampler, max number of annotations, etc.
- stdout_exporter_enabled
- (bool) Enables the stdout exporter if set to true. This is intended for debugging purposes.
- stackdriver_exporter_enabled
- (bool) Enables the Stackdriver exporter if set to true. The project_id must also be set.
- stackdriver_project_id
- (string) The Cloud project_id to use for Stackdriver tracing.
- zipkin_exporter_enabled
- (bool) Enables the Zipkin exporter if set to true. The url and service name must also be set.
- zipkin_url
- (string) The URL to Zipkin, e.g. “http://127.0.0.1:9411/api/v2/spans”
- zipkin_service_name
- (string) The Zipkin service name.
- incoming_trace_context
- (config.trace.v2.OpenCensusConfig.TraceContext) List of incoming trace context headers we will accept. First one found wins.
- outgoing_trace_context
- (config.trace.v2.OpenCensusConfig.TraceContext) List of outgoing trace context headers we will produce.
Enum config.trace.v2.OpenCensusConfig.TraceContext¶
[config.trace.v2.OpenCensusConfig.TraceContext proto]
- NONE
- (DEFAULT) No-op default, no trace context is utilized.
- TRACE_CONTEXT
- W3C Trace-Context format “traceparent:” header.
- GRPC_TRACE_BIN
- Binary “grpc-trace-bin:” header.
- CLOUD_TRACE_CONTEXT
- ”X-Cloud-Trace-Context:” header.
config.trace.v2.TraceServiceConfig¶
[config.trace.v2.TraceServiceConfig proto]
Configuration structure.
{
"grpc_service": "{...}"
}
- grpc_service
- (core.GrpcService, REQUIRED) The upstream gRPC cluster that hosts the metrics service.
