TLS / SSL

The Apache SkyWalking output plugin supports TLS/SSL. For more details about the properties available and general configuration, see TLS/SSL.

Get started

To start inserting records into an Apache SkyWalking service, you can run the plugin through the configuration file.

Configuration file

In your main configuration file append the following:

fluent-bit.yaml

pipeline:
  inputs:
    - name: cpu

  outputs:
    - name: skywalking
      svc_name: dummy-service
      svc_inst_name: dummy-service-fluentbit

fluent-bit.conf

Output format

The format of the plugin output follows the data collect protocol.

For example, if the log is as follows:

{
  "log": "This is the original log message"
}

This message is packed into the following protocol format and written to the OAP using the REST API.

[{
  "timestamp": 123456789,
  "service": "dummy-service",
  "serviceInstance": "dummy-service-fluentbit",
  "body": {
    "json": {
      "json": "{\"log\": \"This is the original log message\"}"
    }
  }
}]
