Tried to install
bin/logstash-plugin install --local --no-verify /tmp/logstash-core-2.3.4-java.gem
but I keep getting the HTTPError. I tried setting the HTTP_PROXY=http://127.0.0.1:3128
still same issue. I will definitely not be able to access rubygems.org from my node due to security reasons. Any workaround for this will be greatly appreciated.
All these effort is to install logstash-output-zabbix which fails.
