# SkyWalking

The **Apache SkyWalking** output plugin, allows to flush your records to a [Apache SkyWalking](https://skywalking.apache.org/) OAP. The following instructions assumes that you have a fully operational Apache SkyWalking OAP in place.

## Configuration Parameters

| parameter       | description                                              | default    |
| --------------- | -------------------------------------------------------- | ---------- |
| host            | Hostname of Apache SkyWalking OAP                        | 127.0.0.1  |
| port            | TCP port of the Apache SkyWalking OAP                    | 12800      |
| auth\_token     | Authentication token if needed for Apache SkyWalking OAP | None       |
| svc\_name       | Service name that fluent-bit belongs to                  | sw-service |
| svc\_inst\_name | Service instance name of fluent-bit                      | fluent-bit |

### TLS / SSL

Apache SkyWalking output plugin supports TTL/SSL, for more details about the properties available and general configuration, please refer to the [TLS/SSL](https://github.com/fluent/fluent-bit-docs/tree/16f30161dc4c79d407cd9c586a0c6839d0969d97/pipeline/configuration/tls_ssl.md) section.

## Getting Started

In order 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 *Input* & *Output* sections:

```
[INPUT]
    Name cpu

[OUTPUT]
    Name skywalking
    svc_name dummy-service
    svc_inst_name dummy-service-fluentbit
```

## Output Format

The format of the plugin output follows the [data collect protocol](https://github.com/apache/skywalking-data-collect-protocol/blob/743f33119dc5621ae98b596eb8b131dd443445c7/logging/Logging.proto).

For example, if we get log as follows,

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

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

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