i have this Error : FATAL logstash.runner - Logstash could not be started because there is already another instance using the configured data directory. If you wish to run multiple instances, you must change the "path.data" setting.
help please

Either you run one instance of Logstash with all configs, or you need to install separate instances with different data directories.

What is it you are trying to do? Which operating system are you using? How did you install Logstash?

This is how i start my logstash specifying path.data
{logstash\_home}/bin/logstash -f /usr/share/logstash/kafka-solr-pipeline.conf --config.reload.automatic --path.data /usr/share/logstash/data/1

If you install using RPM I do not think there is any automatic way to create multiple services, so you may be better off separating the processing flows in your configuration files using conditionals and have a single Logstash instance process them all.

Update all your config files with tags and associated [conditionals](https://www.elastic.co/guide/en/logstash/5.5/event-dependent-configuration.html#conditionals) so that they can be merged into a single config without issues, and then put them all into the Logstash [config directory](https://www.elastic.co/guide/en/logstash/5.5/dir-layout.html), which should be `/etc/logstash/conf.d` by default.

Easiest way is to add a distinct tag for each input using the `tags` parameter and then use conditionals to ensure that the correct filters and outputs are applied. Something like this:
```auto
input {
jdbc {
...
tags =>["jdbc1"]
}
}
filter {
if "jdbc1" in [tags] {
...
}
}
output {
if "jdbc1" in [tags] {
elasticsearch {
...
}
}
}
```
