Issues

The otlp_http exporter sends logs, metrics, profiles and traces via HTTP using OTLP format.

The otlphttp deprecated alias exists for the component name. It will be removed in a future version. If you use the deprecated alias otlphttp in your configuration, change it to otlp_http.

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).
• profiles_endpoint (no default): The target URL to send profile data to (e.g.: https://example.com:4318/v1development/profiles). If this setting is present the endpoint setting is ignored for logs.
• tls: see TLS Configuration Settings for the full set of available options.
• 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.
• encoding (default = proto): The encoding to use for the messages (valid options: proto, json)
• retry_on_failure: see Retry on Failure for the full set of available options.
• sending_queue: see Sending Queue for the full set of available options.

Example:

exporters:
  otlp_http:
    endpoint: https://example.com:4318

By default gzip compression is enabled. See compression comparison for details benchmark information. To disable, configure as follows:

exporters:
  otlp_http:
    ...
    compression: none

By default proto encoding is used, to change the content encoding of the message configure it as follows:

exporters:
  otlp_http:
    ...
    encoding: json
