An output plugin to submit Logs, Metrics, or Traces to an OpenTelemetry endpoint
The OpenTelemetry plugin allows you to take logs, metrics, and traces from Fluent Bit and submit them to an OpenTelemetry HTTP endpoint.
Important Note: At the moment only HTTP endpoints are supported.
| Key | Description | Default |
|---|---|---|
The OpenTelemetry plugin works with logs and only the metrics collected from one of the metric input plugins. In the following example, log records generated by the dummy plugin and the host metrics collected by the node exporter metrics plugin are exported by the OpenTelemetry output plugin.
host
IP address or hostname of the target HTTP Server
127.0.0.1
http_user
Basic Auth Username
http_passwd
Basic Auth Password. Requires HTTP_user to be set
port
TCP port of the target HTTP Server
80
proxy
Specify an HTTP Proxy. The expected format of this value is http://HOST:PORT. Note that HTTPS is not currently supported. It is recommended not to set this and to configure the HTTP proxy environment variables instead as they support both HTTP and HTTPS.
metrics_uri
Specify an optional HTTP URI for the target web server listening for metrics, e.g: /v1/metrics
/
logs_uri
Specify an optional HTTP URI for the target web server listening for logs, e.g: /v1/logs
