public class LogsCollector
extends AbstractCollector<io.opentelemetry.proto.collector.logs.v1.ExportLogsServiceRequest,io.opentelemetry.proto.collector.logs.v1.ExportLogsServiceResponse,Log>

Processes incoming OpenTelemetry logs packets - extracts individual Logs from a packet and queues them to all LogsSubscribers. Also notifies the client on potential errors.

LogsCollector

public LogsCollector(io.grpc.MethodDescriptor<io.opentelemetry.proto.collector.logs.v1.ExportLogsServiceRequest,io.opentelemetry.proto.collector.logs.v1.ExportLogsServiceResponse> exportMethod,
 Instrumentation otel)

Creates a new logs collector to be added to a Vert.x routing context.

Parameters:

exportMethod - the gRPC method to be attached to

otel - a helper for own telemetry needs

Method Details

loadBatch

public Batch<Log> loadBatch(io.opentelemetry.proto.collector.logs.v1.ExportLogsServiceRequest request,
 String transport,
 String encoding,
 io.opentelemetry.context.Context otelContext)

Processes incoming packets (or batches) - extracts and publishes the contained OpenTelemetry LogRecords (one by one) to all LogsSubscribers.

Specified by:

loadBatch in class AbstractCollector<io.opentelemetry.proto.collector.logs.v1.ExportLogsServiceRequest,io.opentelemetry.proto.collector.logs.v1.ExportLogsServiceResponse,Log>

Parameters:

request - the client's OTLP request

transport - the OTLP transport - "grpc" or "http"

encoding - the OTLP encoding - "protobuf" or "json"

otelContext - the Context used for own telemetry

Returns:

a new Batch with all items of the request

getBatchResponse

public io.opentelemetry.proto.collector.logs.v1.ExportLogsServiceResponse getBatchResponse(io.opentelemetry.proto.collector.logs.v1.ExportLogsServiceRequest request,
 Batch<Log> completedBatch,
 String transport,
 String encoding)

Called to compute the correct response to the client after an entire batch (or packet) of OpenTelemetry logs, metrics or spans has been processed.

Specified by:

getBatchResponse in class AbstractCollector<io.opentelemetry.proto.collector.logs.v1.ExportLogsServiceRequest,io.opentelemetry.proto.collector.logs.v1.ExportLogsServiceResponse,Log>

Parameters:

request - the original request from the client

completedBatch - the completed batch of records

transport - the OTLP transport used - "grpc" or "http"

encoding - - the OTLP encoding - "protobuf" or "json"

Returns:

the correct OTLP reposne to be sent back to the client

telemetrySignalType

protected String telemetrySignalType()

Returns "logs" as the signal type for this collector's own telemetry.

Specified by:

telemetrySignalType in class AbstractCollector<io.opentelemetry.proto.collector.logs.v1.ExportLogsServiceRequest,io.opentelemetry.proto.collector.logs.v1.ExportLogsServiceResponse,Log>

Returns:

the signal type
