var ( // HTTPSpanMiddleware is an http.Handler middleware to create spans for the HTTP endpoint. HTTPSpanMiddleware = HTTPSpanIgnoringPaths() )
Functions ¶
func HTTPSpanIgnoringPaths ¶
HTTPSpanIgnoringPaths is an http.Handler middleware to create spans for the HTTP endpoint, not sampling any request whose path is in pathsToIgnore.
func SetupDynamicPublishing ¶
func SetupDynamicPublishing(logger *zap.SugaredLogger, configMapWatcher configmap.Watcher, serviceName, tracingConfigName string) error
SetupDynamicPublishing sets up trace publishing for the process, by watching a ConfigMap for the configuration. Note that other pieces still need to generate the traces, this just ensures that if generated, they are collected appropriately. This is normally done by using tracing.HTTPSpanMiddleware as a middleware HTTP handler. The configuration will be dynamically updated when the ConfigMap is updated.
func SetupStaticPublishing ¶
SetupStaticPublishing sets up trace publishing for the process. Note that other pieces still need to generate the traces, this just ensures that if generated, they are collected appropriately. This is normally done by using tracing.HTTPSpanMiddleware as a middleware HTTP handler. The configuration will not be dynamically updated.
Types ¶
type ConfigOption ¶
ConfigOption is the interface for adding additional exporters and configuring opencensus tracing.
func WithExporter ¶
func WithExporter(name string, logger *zap.SugaredLogger) ConfigOption
WithExporter returns a ConfigOption for use with NewOpenCensusTracer that configures it to export traces based on the configuration read from config-tracing.
func WithExporterFull ¶
func WithExporterFull(name, host string, logger *zap.SugaredLogger) ConfigOption
WithExporterFull supports host argument for WithExporter. The host arg is used for a value of tag ip="{IP}" so you can use an actual IP. Otherwise, the host name must be able to be resolved. e.g)
"name" is a service name like activator-service. "host" is a endpoint IP like activator-service's endpoint IP.
func WithZipkinExporter
deprecated
func WithZipkinExporter(reporterFact ZipkinReporterFactory, endpoint *zipkinmodel.Endpoint) ConfigOption
WithZipkinExporter returns a config with zipkin enabled.
Deprecated: This function is the legacy entrypoint and should be replaced with one of:
- WithExporter() in production code
- testing/FakeZipkinExporter() in test code.
type OpenCensusTracer ¶
type OpenCensusTracer struct {
// contains filtered or unexported fields
}
OpenCensusTracer is responsible for managing and updating configuration of OpenCensus tracing
func NewOpenCensusTracer ¶
func NewOpenCensusTracer(configOptions ...ConfigOption) *OpenCensusTracer
func (*OpenCensusTracer) ApplyConfig ¶
func (oct *OpenCensusTracer) ApplyConfig(cfg *config.Config) error
func (*OpenCensusTracer) Finish ¶
func (oct *OpenCensusTracer) Finish() error
type ZipkinReporterFactory ¶
type ZipkinReporterFactory func(*config.Config) (zipkinreporter.Reporter, error)
ZipkinReporterFactory is a factory function which creates a reporter given a config
