Configuration
You can configure the otel_logs_source source with the following options.
| Option | Type | Description | |
|---|---|---|---|
| port | int | Represents the port that the otel_logs_sourcesource is running on. Default value is21892. | |
| path | string | Represents the path for sending unframed HTTP requests. You can use this option to support an unframed gRPC request with an HTTP idiomatic path to a configurable path. The path should start with /, and its length should be at least 1. The/opentelemetry.proto.collector.logs.v1.LogsService/Exportendpoint is disabled for both gRPC and HTTP requests if the path is configured. The path can contain a${pipelineName}placeholder, which is replaced with the pipeline name. If the value is empty andunframed_requestsistrue, then the source provides the path/opentelemetry.proto.collector.logs.v1.LogsService/Export. | |
| max_request_length | No | ByteCount | The maximum number of bytes allowed in the payload of a single gRPC or HTTP request. Default value is 10mb. | 
| request_timeout | int | Represents the request timeout duration in milliseconds. Default value is 10000. | |
| health_check_service | Boolean | Enables the gRPC health check service under grpc.health.v1/Health/Check. Default value isfalse. | |
| proto_reflection_service | Boolean | Enables a reflection service for Protobuf services (see ProtoReflectionService and gRPC reflection). Default value is false. | |
| unframed_requests | Boolean | Enables requests that are not framed using the gRPC wire protocol. Default value is false. | |
| thread_count | int | The number of threads to keep in the ScheduledThreadPool. Default value is500. | |
| max_connection_count | int | The maximum number of open connections allowed. Default value is 500. |
