OTLP/HTTP Exporter

Exports traces and/or metrics via HTTP using OTLP format.

Supported pipeline types: traces, metrics, logs

⚠️ OTLP logs format is currently marked as "Beta" and may change in incompatible ways.

The following settings are required:

  • endpoint (no default): The target base URL to send data to (e.g.: https://example.com:4318). To send each signal a corresponding path will be added to this base URL, i.e. for traces "/v1/traces" will appended, for metrics "/v1/metrics" will be appended, for logs "/v1/logs" will be appended.

The following settings can be optionally configured:

  • traces_endpoint (no default): The target URL to send trace data to (e.g.: https://example.com:4318/v1/traces). If this setting is present the endpoint setting is ignored for traces.

  • metrics_endpoint (no default): The target URL to send metric data to (e.g.: https://example.com:4318/v1/metrics). If this setting is present the endpoint setting is ignored for metrics.

  • logs_endpoint (no default): The target URL to send log data to (e.g.: https://example.com:4318/v1/logs). If this setting is present the endpoint setting is ignored logs.

  • tls:

    • insecure (default = false): when set to true disables verifying the server's certificate chain and host name. The connection is still encrypted but server identity is not verified.
    • ca_file path to the CA cert. For a client this verifies the server certificate. Should only be used if insecure is set to false.
    • cert_file path to the TLS cert to use for TLS required connections. Should only be used if insecure is set to false.
    • key_file path to the TLS key to use for TLS required connections. Should only be used if insecure is set to false.

  • compression (default = none): Compression type to use (only gzip is supported today)

  • timeout (default = 30s): HTTP request time limit. For details see https://golang.org/pkg/net/http/#Client

  • read_buffer_size (default = 0): ReadBufferSize for HTTP client.

  • write_buffer_size (default = 512 * 1024): WriteBufferSize for HTTP client.

Example:

exporters:
  otlphttp:
    endpoint: https://example.com:4318/v1/traces

The full list of settings exposed for this exporter are documented here with detailed sample configurations here.
