Package otlptracehttp provides an OTLP span exporter using HTTP with protobuf payloads.
|
|
By default the telemetry is sent to https://localhost:4318/v1/traces.
|
|
|
|
Exporter should be created using [New].
|
|
|
|
The environment variables described below can be used for configuration.
|
|
|
|
OTEL_EXPORTER_OTLP_ENDPOINT (default: "https://localhost:4318") -
|
|
target base URL ("/v1/traces" is appended) to which the exporter sends telemetry.
|
|
The value must contain a scheme ("http" or "https") and host.
|
|
The value may additionally contain a port and a path.
|
|
The value should not contain a query string or fragment.
|
|
The configuration can be overridden by OTEL_EXPORTER_OTLP_TRACES_ENDPOINT
|
|
environment variable and by [WithEndpoint], [WithEndpointURL], [WithInsecure] options.
|
|
|
|
OTEL_EXPORTER_OTLP_TRACES_ENDPOINT (default: "https://localhost:4318/v1/traces") -
|
|
target URL to which the exporter sends telemetry.
|
|
The value must contain a scheme ("http" or "https") and host.
|
|
The value may additionally contain a port and a path.
|
|
The value should not contain a query string or fragment.
|
|
The configuration can be overridden by [WithEndpoint], [WithEndpointURL], [WitnInsecure], and [WithURLPath] options.
|
|
|
|
OTEL_EXPORTER_OTLP_HEADERS, OTEL_EXPORTER_OTLP_TRACES_HEADERS (default: none) -
|
|
key-value pairs used as headers associated with HTTP requests.
|
|
The value is expected to be represented in a format matching to the [W3C Baggage HTTP Header Content Format],
|
|
except that additional semi-colon delimited metadata is not supported.
|
|
Example value: "key1=value1,key2=value2".
|
|
OTEL_EXPORTER_OTLP_TRACES_HEADERS takes precedence over OTEL_EXPORTER_OTLP_HEADERS.
|
|
The configuration can be overridden by [WithHeaders] option.
|
|
|
|
OTEL_EXPORTER_OTLP_TIMEOUT, OTEL_EXPORTER_OTLP_TRACES_TIMEOUT (default: "10000") -
|
|
maximum time in milliseconds the OTLP exporter waits for each batch export.
|
|
OTEL_EXPORTER_OTLP_TRACES_TIMEOUT takes precedence over OTEL_EXPORTER_OTLP_TIMEOUT.
|
|
The configuration can be overridden by [WithTimeout] option.
|
|
|
|
OTEL_EXPORTER_OTLP_COMPRESSION, OTEL_EXPORTER_OTLP_TRACES_COMPRESSION (default: none) -
|
|
the compression strategy the exporter uses to compress the HTTP body.
|
|
Supported value: "gzip".
|
|
OTEL_EXPORTER_OTLP_TRACES_COMPRESSION takes precedence over OTEL_EXPORTER_OTLP_COMPRESSION.
|
|
The configuration can be overridden by [WithCompression] option.
|
|
|
|
OTEL_EXPORTER_OTLP_CERTIFICATE, OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE (default: none) -
|
|
the filepath to the trusted certificate to use when verifying a server's TLS credentials.
|
|
OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE takes precedence over OTEL_EXPORTER_OTLP_CERTIFICATE.
|
|
The configuration can be overridden by [WithTLSClientConfig] option.
|
|
|
|
OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE, OTEL_EXPORTER_OTLP_TRACES_CLIENT_CERTIFICATE (default: none) -
|
|
the filepath to the client certificate/chain trust for clients private key to use in mTLS communication in PEM format.
|
|
OTEL_EXPORTER_OTLP_TRACES_CLIENT_CERTIFICATE takes precedence over OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE.
|
|
The configuration can be overridden by [WithTLSClientConfig] option.
|
|
|
|
OTEL_EXPORTER_OTLP_CLIENT_KEY, OTEL_EXPORTER_OTLP_TRACES_CLIENT_KEY (default: none) -
|
|
the filepath to the clients private key to use in mTLS communication in PEM format.
|
|
