An output plugin to submit Metrics to an OpenTelemetry endpoint |
The OpenTelemetry plugin allows you to take metrics from Fluent Bit and submit them to an OpenTelemetry HTTP endpoint.
Important Note: At the moment only HTTP endpoints are supported.
Key | Description | Default |
---|---|---|
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. |
|
uri | Specify an optional HTTP URI for the target web server, e.g: /something | / |
header | Add a HTTP header key/value pair. Multiple headers can be set. | |
log_response_payload | Log the response payload within the Fluent Bit log | false |
add_label | This allows you to add custom labels to all metrics exposed through the OpenTelemetry exporter. You may have multiple of these fields |
The OpenTelemetry plugin only works with metrics collected by one of the from metric input plugins. In the following example, host metrics are collected by the node exporter metrics plugin and then delivered by the OpenTelemetry output plugin.
