Description
The purpose and use-cases of the new component
**Context : **
Currently, OpenTelemetry does not have a native exporter designed to push data to a custom HTTP endpoint. This PR introduces a Webhook Exporter that allows OpenTelemetry to send log data, metrics, or traces to an HTTP endpoint. This feature is useful for pushing OpenTelemetry data to systems that accept HTTP-based ingestion but do not have specific OpenTelemetry support.
Problem :
There are cases where organizations need to push telemetry data to external systems that accept HTTP requests, such as custom logging systems, third-party services, or RESTful APIs. OpenTelemetry's existing exporters might not fit the needs for sending data via webhooks or HTTP.
**Proposed Solution : **
This PR introduces a new Webhook Exporter that allows OpenTelemetry to send data to any configured HTTP endpoint using a simple HTTP POST request. This exporter supports sending logs, traces, or metrics in a configurable payload format (JSON, etc.).
The key features of the Webhook Exporter include:
Customizable HTTP Endpoint: Users can specify the HTTP endpoint URL to send the data.
Payload Format: Supports configuring the format (e.g., JSON or raw data) for the POST request body.
Authentication: Ability to configure basic authentication, API keys, or other methods for HTTP requests.
Retry Mechanism: Configurable retry logic in case of network failures or HTTP errors.
Example Configuration
Here’s an example configuration for the Webhook Exporter:
yaml :
exporters:
webhook:
endpoint: "https://example.com/telemetry" # The endpoint to send data
encoding: json # Encoding format for payload (e.g., json, raw)
headers:
Content-Type: application/json
Authorization: "Bearer "
retry:
enabled: true
max_retries: 5
backoff_interval: 2s
Implementation Details
HTTP POST Requests: The exporter sends telemetry data using HTTP POST requests. The payload will contain serialized telemetry data in the specified encoding format (e.g., JSON).
Custom Headers & Authentication: The exporter supports configuring custom HTTP headers, which may include authorization tokens, API keys, or other authentication mechanisms.
Error Handling & Retries: If the HTTP request fails, the exporter will automatically retry based on the configured retry logic.
Benefits :
- Flexibility: Users can send telemetry data to any external HTTP-based system.
- Customizability: Full control over the payload format, authentication, and headers.
- Reliability: Built-in retry mechanism to handle transient network failures.
