Do you really need to run multiple instances of Logstash? That's usually not necessary and is rather wasteful of resources (primarily RAM).

But if you insist, the data directory must be unique to each instance. You can use different logstash.yml files or use the `--path.data` option when starting Logstash.

Yes, look at [multiple pipelines in the docs](https://www.elastic.co/guide/en/logstash/6.3/multiple-pipelines.html).
