+# Dynatrace
+
+Stream logs to [Dynatrace](https://www.dynatrace.com) by utilizing the **http**
+plugin to send data to the
+[Dynatrace generic log ingest API](https://docs.dynatrace.com/docs/shortlink/lma-generic-log-ingestion).
+
+## Configuration parameters
+
+| Key                        | Description | Default |
+| -------------------------- | ----------- | ------- |
+| `header`                   | The specific header for content-type. | `Content-Type application/json; charset=utf-8` |
+| `header`                   | The specific header for authorization token, where {your-API-token-here} is the Dynatrace API token with log ingest scope. | Authorization Api-Token {your-API-token-here} |
+| `allow_duplicated_headers` | Specifies duplicated header use. | `false` |
+| `host`                     | Your Dynatrace environment hostname where {your-environment-id} is your environment ID. | `{your-environment-id}.live.dynatrace.com` |
+| `port`                     | TCP port of your Dynatrace host. | `443` |
+| `uri`                      | Specify the HTTP URI for Dynatrace log ingest API. | `/api/v2/logs/ingest` |
+| `format`                   | The data format to be used in the HTTP request body. | `json` |
+| `json_date_format`         | Date format standard for JSON. | `iso8601` |
+| `json_date_key`            | Fieldname specifying message timestamp. | `timestamp` |
+| `tls`                      | Specify to use TLS. | `on` |
+| `tls.verify`               | TLS verification. | `on` |
+
+## Getting started
+
+To get started with sending logs to Dynatrace:
+
+1. Get a [Dynatrace API](https://docs.dynatrace.com/docs/shortlink/api-authentication)
+   token with the `logs.ingest` (Ingest Logs) scope.
+1. Determine your Dynatrace
+   [environment ID](https://docs.dynatrace.com/docs/shortlink/monitoring-environment#environment-id).
+1. In your main Fluent Bit configuration file, append the following `Output` section:
+
+   ```text
+   [OUTPUT]
+       name         http
+       match        *
+       header       Content-Type application/json; charset=utf-8
+       header       Authorization Api-Token {your-API-token-here}
+       allow_duplicated_headers false
+       host         {your-environment-id}.live.dynatrace.com
+       Port         443
+       URI          /api/v2/logs/ingest
+       Format       json
+       json_date_format iso8601
+       json_date_key timestamp
+       tls          On
+       tls.verify   On
