I have a problem with logstash, when I running like this:/usr/share/logstash/bin/logstash --debug -f /etc/logstash/conf.d/switch.conf  
Works fine and start this specific configuration file.

But I put this conf file in pipelines.yml, and when I tried to run my logstash through systemctl start logstash.service , appears status OK, but the configuration switch.conf not starts. Another strange behavior I`m see, that the log files folder /var/log/logstash still empty with no logs.

The config files are bellow:

# cat /etc/logstash/logstash.yml |grep -v ^#

path.data: /var/lib/logstash  
pipeline.ordered: auto

path.logs: /var/log/logstash

* * *

# cat pipelines.yml

# This file is where you define your pipelines. You can define multiple.

# For more information on multiple pipelines, see the documentation:

# [Multiple Pipelines | Logstash](https://www.elastic.co/guide/en/logstash/current/multiple-pipelines.html)

- pipeline.id: main  
path.config: "/etc/logstash/conf.d/\*.conf"
- pipeline.id: switch  
path.config: "/etc/logstash/conf.d/switch.conf"

This is your `pipelines.yml` ?

```auto
- pipeline.id: main
  path.config: "/etc/logstash/conf.d/*.conf"
- pipeline.id: switch
  path.config: "/etc/logstash/conf.d/switch.conf"

```

If so, this is wrong, it will make logstash read the `switch.conf` twice, the `main` pipeline will read all the `.conf` files inside the `conf.d` directory.

If your `switch.conf` pipeline is listening on some port, it will not run when logstash tries to start the `switch` pipeline as it would already be listening when the `main` pipeline was started.

Remove the first two lines and try to use this `pipelines.yml`

```auto
- pipeline.id: switch
  path.config: "/etc/logstash/conf.d/switch.conf"

```
