Well, the error message suggests that /home/cmarwa/logstash-5.5.0/bin/simple.conf doesn't exist.

I did specify the path of the file simple.conf but the same error still appear.In fact , it is mentionned that the pipeline is created but why the error still appear.I don't know if logs must be saved in log4j2.properties.
have a look to this
