Regards
I have a problem when starting an instance of **Logstash 6.6** with multiple pipelines, each pipeline will query an **Oracle** DB, these queries will generate a set of JSON data that will be showed at **Kibana** in a Dashboard. Each of these data pipelines separately works fine, but I need to converge all information. For this I want to take advantage of the utility of multiple pipelines in a single instance of Logstash that since version 6.x exists.
The logstash.yml contains:
xpack.monitoring.enabled: true
xpack.monitoring.elasticsearch.url: "[https://localhost:9200](https://localhost:9200)"
xpack.monitoring.elasticsearch.sniffing: true
xpack.monitoring.collection.interval: 10s
xpack.monitoring.collection.pipeline.details.enabled: true
pipelines.yml contains:
- pipeline.id:PROSEM\_DEMANDA\_5\_ANNO
pipeline.workers: 1
pipeline.output.workers: 1
pipeline.batch.size: 1
queue.type: memory
path.config: "config/pipelines/v\_prosem\_CAB\_demanda\_anno.cfg"
- pipeline.id:PROSEM\_CONTRATACIONES\_5\_ANNO
pipeline.workers: 2
pipeline.output.workers: 2
pipeline.batch.size: 1
queue.type: memory
path.config: "config/pipelines/v\_prosem\_cab\_contr.cfg"
the log spits the following error:
```

I have checked the way to tell the attribute path.config: "config/pipelines/v\_prosem\_cab\_contr.cfg" on **Windows** 😫 systems as I see at : [Logstash Multiple Pipelines Doesn't work](https://discuss.elastic.co/t/logstash-multiple-pipelines-doesnt-work/110251)
All help is welcome thank you in advance
