# Docker compose Logstash integration with VictoriaLogs

The folder contains examples of [Logstash](https://www.elastic.co/logstash) integration with VictoriaLogs using protocols:

* [loki](./loki)
* [jsonline single node](./jsonline)
* [jsonline HA setup](./jsonline-ha)
* [elasticsearch](./elasticsearch)

All required plugins, that should be installed in order to support protocols listed above can be found in a [Dockerfile](./Dockerfile)

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:

* logstash - logs collection agent configured to collect and write data to `victorialogs`
* victorialogs - logs database, receives data from `logstash` agent
* victoriametrics - metrics database, which collects metrics from `victorialogs` and `logstash` for observability purposes

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)

Logstash configuration example can be found below:
* [loki](./loki/pipeline.conf)
* [jsonline single node](./jsonline/pipeline.conf)
* [jsonline HA setup](./jsonline-ha/pipeline.conf)
* [elasticsearch](./elasticsearch/pipeline.conf)

Please, note that `_stream_fields` parameter must follow recommended [best practices](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) to achieve better performance.
