OTLP Exporter Configuration
Endpoint Configuration
The following environment variables let you configure an OTLP/gRPC or OTLP/HTTP endpoint for your traces, metrics, and logs.
OTEL_EXPORTER_OTLP_ENDPOINT
A base endpoint URL for any signal type, with an optionally-specified port number. Helpful for when you’re sending more than one signal to the same endpoint and want one environment variable to control the endpoint.
Default value:
- gRPC:
"http://localhost:4317" - HTTP:
"http://localhost:4318"
Example:
- gRPC:
export OTEL_EXPORTER_OTLP_ENDPOINT="my-api-endpoint:443" - HTTP:
export OTEL_EXPORTER_OTLP_ENDPOINT="http://my-api-endpoint/"
For OTLP/HTTP, exporters in the SDK construct signal-specific URLs when this environment variable is set. This means that if you’re sending traces, metrics, and logs, the following URLS are constructed from the example above:
- Traces:
"http://my-api-endpoint/v1/traces" - Metrics:
"http://my-api-endpoint/v1/metrics" - Logs:
"http://my-api-endpoint/v1/logs"
OTEL_EXPORTER_OTLP_TRACES_ENDPOINT
Endpoint URL for trace data only, with an optionally-specified port number. Must
end with v1/traces if using OTLP/HTTP.
Default value:
- gRPC:
"http://localhost:4317" - HTTP:
"http://localhost:4318/v1/traces"
Example:
- gRPC:
export OTEL_EXPORTER_OTLP_TRACES_ENDPOINT="my-api-endpoint:443" - HTTP:
export OTEL_EXPORTER_OTLP_TRACES_ENDPOINT="http://my-api-endpoint/v1/traces"
OTEL_EXPORTER_OTLP_METRICS_ENDPOINT
Endpoint URL for metric data only, with an optionally-specified port number. Must
end with v1/metrics if using OTLP/HTTP.
Default value:
- gRPC:
"http://localhost:4317" - HTTP:
"http://localhost:4318/v1/metrics"
Example:
- gRPC:
export OTEL_EXPORTER_OTLP_METRICS_ENDPOINT="my-api-endpoint:443" - HTTP:
export OTEL_EXPORTER_OTLP_METRICS_ENDPOINT="http://my-api-endpoint/v1/metrics"
OTEL_EXPORTER_OTLP_LOGS_ENDPOINT
Endpoint URL for log data only, with an optionally-specified port number. Must
end with v1/logs if using OTLP/HTTP.
Default value:
- gRPC:
"http://localhost:4317" - HTTP:
"http://localhost:4318/v1/logs"
Example:
- gRPC:
export OTEL_EXPORTER_OTLP_LOGS_ENDPOINT="my-api-endpoint:443" - HTTP:
export OTEL_EXPORTER_OTLP_LOGS_ENDPOINT="http://my-api-endpoint/v1/logs"
Header configuration
The following environment variables let you configure additional headers as a list of key-value pairs to add in outgoing gRPC or HTTP requests
OTEL_EXPORTER_OTLP_HEADERS
A list of headers to apply to all outgoing data (traces, metrics, and logs).
Default value: N/A
Example:
export OTEL_EXPORTER_OTLP_HEADERS="api-key=key,other-config-value=value"
OTEL_EXPORTER_OTLP_TRACES_HEADERS
A list of headers to apply to all outgoing traces.
Default value: N/A
Example:
export OTEL_EXPORTER_OTLP_TRACES_HEADERS="api-key=key,other-config-value=value"
OTEL_EXPORTER_OTLP_METRICS_HEADERS
A list of headers to apply to all outgoing metrics.
Default value: N/A
Example:
export OTEL_EXPORTER_OTLP_METRICS_HEADERS="api-key=key,other-config-value=value"
OTEL_EXPORTER_OTLP_LOGS_HEADERS
A list of headers to apply to all outgoing logs.
Default value: N/A
Example:
export OTEL_EXPORTER_OTLP_LOGS_HEADERS="api-key=key,other-config-value=value"
Timeout Configuration
The following environment variables configure the maximum time (in milliseconds) an OTLP Exporter will wait before transmitting the net batch of data.
OTEL_EXPORTER_OTLP_TIMEOUT
The timeout value for all outgoing data (traces, metrics, and logs) in milliseconds.
Default value: 10000 (10s)
Example:
export OTEL_EXPORTER_OTLP_TIMEOUT=500
OTEL_EXPORTER_OTLP_TRACES_TIMEOUT
The timeout value for all outgoing traces in milliseconds.
Default value: 10000 (10s)
Example:
export OTEL_EXPORTER_OTLP_TRACES_TIMEOUT=500
OTEL_EXPORTER_OTLP_METRICS_TIMEOUT
The timeout value for all outgoing metrics in milliseconds.
Default value: 10000 (10s)
Example:
export OTEL_EXPORTER_OTLP_METRICS_TIMEOUT=500
OTEL_EXPORTER_OTLP_LOGS_TIMEOUT
The timeout value for all outgoing logs in milliseconds.
Default value: 10000 (10s)
Example:
export OTEL_EXPORTER_OTLP_LOGS_TIMEOUT=500
OTEL_EXPORTER_OTLP_PROTOCOL
Specifies the OTLP transport protocol to be used for all telemetry data.
Default value: SDK-dependent, but will typically be either http/protobuf or grpc.
Example:
export OTEL_EXPORTER_OTLP_PROTOCOL=grpc
Valid values are:
grpcto use OTLP/gRPChttp/protobufto use OTLP/HTTP+protobufhttp/jsonto use OTLP/HTTP+protobuf
OTEL_EXPORTER_OTLP_TRACES_PROTOCOL
Specifies the OTLP transport protocol to be used for trace data.
Default value: SDK-dependent, but will typically be either http/protobuf or grpc.
Example:
export OTEL_EXPORTER_OTLP_TRACES_PROTOCOL=grpc
Valid values are:
grpcto use OTLP/gRPChttp/protobufto use OTLP/HTTP+protobufhttp/jsonto use OTLP/HTTP+protobuf
OTEL_EXPORTER_OTLP_METRICS_PROTOCOL
