hello_world
in fact the pipeline was created successfully but i don't get the reasons why all these errors appeared !!!! i have to fix them please any help !!!!!

2

did you run it like
$ sudo bin/logstash -e 'input { stdin { } } output { stdout {} }' ?

3

Thank you very much ,i tryed and every thing went well
so the problm maintains in the permission ??

4

Yes, as a user you need to run it using sudo

5

just one an other question, is it necessary to create a config file for the pipeline in /etc/logstash/conf.d because i installed logstash in /opt/ and did not find logstash directory in /etc/ so does it pose a problem ??

6

Yes you need to

7

last day everything worked with sudo , i did not change anything , i am trying now but look an an error appears
sudo bin/logstash -e 'input { stdin { } } output { stdout {} }'
