# Docker compose Logstash integration with VictoriaLogs for given below protocols:

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

It is required to use [OpenSearch plugin](https://github.com/opensearch-project/logstash-output-opensearch) for output configuration.
Plugin can be installed by using the following command:
```
bin/logstash-plugin install logstash-output-opensearch
```
OpenSearch plugin is required because elasticsearch output plugin performs various checks for Elasticsearch version and license which are not applicable for VictoriaLogs.

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 - logstash is configured to accept `syslog` on `5140` port, you can find configuration in the `pipeline.conf`. It writes data in VictoriaLogs
* VictoriaLogs - the log database, it accepts the data from `logstash` by elastic protocol

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.
