Hi all,

Hope you can help. I’m keen to try the multiple pipelines functionality in logstash-6.0.0-alpha2. So far I’ve been unable to get it to work. I’ve edited the “pipelines.yml” file in the config folder. I’ve added the following (fyi - the hyphens are coming out as bullets on this forum post):

- [pipeline.id](http://pipeline.id): pipeline1  
path.config: "c:\aconfigfile1.config"
- [pipeline.id](http://pipeline.id): pipeline2  
path.config: "c:\aconfigfile2.config"

I receive the following error when launching Logstash:

* * *

[2017-08-02T11:01:29,433][ERROR][logstash.agent] An exception happene  
d when converging configuration {:exception=\>RuntimeError, :message=\>"Could not  
fetch the configuration, message: undefined method `pipeline_id' for nil:NilClas s", :backtrace=>["C:/logstash-6.0.0-alpha2/logstash-core/lib/logstash/agent .rb:153:in`converge\_state\_and\_update'", "C: /logstash-6.0.0-alpha2/logstash

1:in `call'", "C:/ logstash-6.0.0-alpha2/vendor/bundle/jruby/1.9/gems/stud-0 .0.22/lib/stud/task.rb:24:in`initialize'"]}

* * *

I’m wondering whether the path to the configuration file is in the wrong format (or I've perhaps put the file in the wrong location). Has anyone else had any success with multiple pipelines in logstash-6.0.0-alpha2? Any advice appreciated. I'm running Logstash on MS Server 2008 with Java SE runtime 8u144 x64.

Many thanks….
