Types ¶
type Agent ¶
type Agent struct {
Receiver *api.HTTPReceiver
OTLPReceiver *api.OTLPReceiver
Concentrator *stats.Concentrator
ClientStatsAggregator *stats.ClientStatsAggregator
Blacklister *filters.Blacklister
Replacer *filters.Replacer
PrioritySampler *sampler.PrioritySampler
ErrorsSampler *sampler.ErrorsSampler
RareSampler *sampler.RareSampler
NoPrioritySampler *sampler.NoPrioritySampler
EventProcessor *event.Processor
TraceWriter *writer.TraceWriter
StatsWriter *writer.StatsWriter
RemoteConfigHandler *remoteconfighandler.RemoteConfigHandler
TelemetryCollector telemetry.TelemetryCollector
DebugServer *api.DebugServer
Statsd statsd.ClientInterface
Timing timing.Reporter
// DiscardSpan will be called on all spans, if non-nil. If it returns true, the span will be deleted before processing.
DiscardSpan func(*pb.Span) bool
// ModifySpan will be called on all non-nil spans of received trace chunks.
// Note that any modification of the trace chunk could be overwritten by subsequent ModifySpan calls.
ModifySpan func(*pb.TraceChunk, *pb.Span)
// In takes incoming payloads to be processed by the agent.
In chan *api.Payload
// contains filtered or unexported fields
}
Agent struct holds all the sub-routines structs and make the data flow between them
func NewAgent ¶
func NewAgent(ctx context.Context, conf *config.AgentConfig, telemetryCollector telemetry.TelemetryCollector, statsd statsd.ClientInterface) *Agent
NewAgent returns a new Agent object, ready to be started. It takes a context which may be cancelled in order to gracefully stop the agent.
func (*Agent) FlushSync ¶
func (a *Agent) FlushSync()
FlushSync flushes traces sychronously. This method only works when the agent is configured in synchronous flushing mode via the apm_config.sync_flush option.
func (*Agent) Process ¶
Process is the default work unit that receives a trace, transforms it and passes it downstream.
func (*Agent) ProcessStats ¶
func (a *Agent) ProcessStats(in *pb.ClientStatsPayload, lang, tracerVersion string)
ProcessStats processes incoming client stats in from the given tracer.
func (*Agent) Run ¶
func (a *Agent) Run()
Run starts routers routines and individual pieces then stop them when the exit order is received.
func (*Agent) SetGlobalTagsUnsafe ¶
SetGlobalTagsUnsafe sets global tags to the agent configuration. Unsafe for concurrent use.
