Seems the important one is:</P><P style="margin-left: 20px;">Path "/usr/share/logstash/data" must be a writable directory. It is not writable.</P><P>After setting the permissions of /usr/share/logstash/data your command line should work. <BR />However, I would suggest to run Logstash as its proper installed service, with configuration files in /etc/logstash. </P> Thu, 23 Aug 2018 18:47:59 GMT stevenmatison 2018-08-23T18:47:59Z
