# How to set up sending logs to VictoriaLogs from logstash
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.
Here is an example of logstash configuration:
```
opensearch {
hosts => ["http://victorialogs:9428/insert/elasticsearch"]
custom_headers => {
"AccountID" => "0"
"ProjectID" => "0"
}
parameters => {
"_stream_fields" => "host.ip,process.name"
"_msg_field" => "message"
"_time_field" => "@timestamp"
}
}
```
Please, note that `_stream_fields` parameter must follow recommended [best practices](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html#stream-fields) to achieve better performance.
