Native support for OTEL Logs

Native Support for OTEL Logs HTTP Request via OTLP HTTP Exporter

Overview

OpenTelemetry is becoming the standard for observability. OpenTelemetry is vendor-agnostic, and the 2nd most active community on GitHub after Kubernetes. Support for OTEL logs is added under the /v1/json_batch endpoint as /v1/json_batch/otlplogs.

Example OTEL Collector Configuration

codeexporters:
  otlphttp:
    logs_endpoint: https://apicainstance.url/v1/json_batch/otlplogs?namespace=foobar2
    encoding: json
    compression: gzip
    headers:
      Authorization: "Bearer bearer_token_string"
    tls:
      insecure: false
      insecure_skip_verify: true

Mandatory Fields

• logs_endpoint: The endpoint to which logs are sent.

• encoding: Must be set to json.

Optional Fields

• compression: Can be set to gzip for log compression.

• headers: Headers for the HTTP request. It is recommended to use this in production setups.

• tls: TLS configuration. It is recommended to enable TLS in production setups.

Authentication

Authentication is supported via bearer token authentication. Both TLS and non-TLS modes are supported.

Handling of Namespaces/Application

Namespaces and applications default to default_namespace/default_application. They can be customized using either of the following methods:

• Query Parameters: Override URL and namespace using query parameters.

• Explicit Keywords: Include "namespace" and "application" keywords in the attributes.

This documentation covers the setup and configuration of native support for OTEL logs using the OTLP HTTP exporter. Ensure that mandatory fields are correctly configured, and consider enabling optional fields for enhanced security and performance in production environments.
