+The folder contains examples of [DataDog agent](https://docs.datadoghq.com/agent) integration with VictoriaLogs using protocols:
+
+* [datadog](./datadog)
+
+To spin-up environment `cd` to any of listed above directories run the following command:
+```
+docker compose up -d 
+```
+
+To shut down the docker-compose environment run the following command:
+```
+docker compose down
+docker compose rm -f
+```
+
+The docker compose file contains the following components:
+
+* datadog - Datadog logs collection agent, which is configured to collect and write data to `victorialogs`
+* victorialogs - VictoriaLogs log database, which accepts the data from `datadog`
+* victoriametrics - VictoriaMetrics metrics database, which collects metrics from `victorialogs` and `datadog`
+
+Querying the data
+
+* [vmui](https://docs.victoriametrics.com/victorialogs/querying/#vmui) - a web UI is accessible by `http://localhost:9428/select/vmui`
+* for querying the data via command-line please check [these docs](https://docs.victoriametrics.com/victorialogs/querying/#command-line)
+
+Please, note that `_stream_fields` parameter must follow recommended [best practices](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) to achieve better performance.
