otel_logs_source
The otel_logs_source source is an OpenTelemetry source that follows the OpenTelemetry Protocol Specification and receives logs from the OTel Collector in the form of ExportLogsServiceRequest records.
This source supports the OTLP/gRPC protocol.
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_source source is running on. Default value is 21892. |
| 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/Export endpoint 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 and unframed_requests is true, then the path that the source provides is /opentelemetry.proto.collector.logs.v1.LogsService/Export. |
| 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 is false. |
| 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 is 500. |
| max_connection_count | int | The maximum number of open connections allowed. Default value is 500. |
SSL
You can configure SSL in the otel_logs_source source with the following options.
| Option | Type | Description |
|---|---|---|
| ssl | Boolean | Enables TLS/SSL. Default value is true. |
| sslKeyCertChainFile | string | Represents the SSL certificate chain file path or Amazon Simple Storage Service (Amazon S3) path. For example, see the Amazon S3 path s3://<bucketName>/<path>. Required if ssl is set to true. |
| sslKeyFile | string | Represents the SSL key file path or Amazon S3 path. For example, see the Amazon S3 path s3://<bucketName>/<path>. Required if ssl is set to true. |
| useAcmCertForSSL | Boolean | Enables TLS/SSL using a certificate and private key from AWS Certificate Manager (ACM). Default value is false. |
| acmCertificateArn | string | Represents the ACM certificate Amazon Resource Name (ARN). ACM certificates take precedence over Amazon S3 or local file system certificates. Required if useAcmCertForSSL is set to true. |
| awsRegion | string | Represents the AWS Region used by ACM or Amazon S3. Required if useAcmCertForSSL is set to true or sslKeyCertChainFile or sslKeyFile is the Amazon S3 path. |
