| Option | Required | Type | Description |
|---|---|---|---|
| port | No | Integer | The port that the OpenTelemtry metrics source runs on. Default value is 21891. |
| request_timeout | No | Integer | The request timeout, in milliseconds. Default value is 10000. |
| health_check_service | No | Boolean | Enables a gRPC health check service under grpc.health.v1/Health/Check. Default value is false. |
| proto_reflection_service | No | Boolean | Enables a reflection service for Protobuf services (see gRPC reflection and gRPC Server Reflection Tutorial docs). Default value is false. |
| unframed_requests | No | Boolean | Enables requests not framed using the gRPC wire protocol. |
| thread_count | No | Integer | The number of threads to keep in the ScheduledThreadPool. Default value is 200. |
| max_connection_count | No | Integer | The maximum allowed number of open connections. Default value is 500. |
| ssl | No | Boolean | Enables connections to the OpenTelemetry source port over TLS/SSL. Default value is true. |
| sslKeyCertChainFile | Conditionally | String | File-system path or Amazon Simple Storage Service (Amazon S3) path to the security certificate (for example, "config/demo-data-prepper.crt" or "s3://my-secrets-bucket/demo-data-prepper.crt"). Required if ssl is set to true. |
| sslKeyFile | Conditionally | String | File-system path or Amazon S3 path to the security key (for example, "config/demo-data-prepper.key" or "s3://my-secrets-bucket/demo-data-prepper.key"). Required if ssl is set to true. |
| useAcmCertForSSL | No | Boolean | Whether to enable TLS/SSL using a certificate and private key from AWS Certificate Manager (ACM). Default value is false. |
| acmCertificateArn | Conditionally | String | Represents the ACM certificate ARN. ACM certificate take preference over S3 or local file system certificates. Required if useAcmCertForSSL is set to true. |
| awsRegion | Conditionally | String | Represents the AWS Region used by ACM or Amazon S3. Required if useAcmCertForSSL is set to true or sslKeyCertChainFile and sslKeyFile is the Amazon S3 path. |
| authentication | No | Object | An authentication configuration. By default, an unauthenticated server is created for the pipeline. This uses pluggable authentication for HTTPS. To use basic authentication, define the http_basic plugin with a username and password. To provide customer authentication, use or create a plugin that implements GrpcAuthenticationProvider. |
