Today I upgraded logstash to the latest version and needs to install logstash-filter-elapsed plugin.
I'm receiving below error:
./logstash-plugin install logstash-filter-elapsed Using bundled JDK: /usr/share/logstash/jdk warning: no jvm.options file found ERROR: Something went wrong when installing logstash-filter-elapsed, message: Socket closed
probably some ports I need to have open. Can someone tell me which ports I need to have opened to have ability to install plugins ?
