Hello,
I upgraded logstash to the latest version 7.16.3 and I have issues with apply required filters,
Maybe this is related with specific ports closed,
As output I'm receiving below:
./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
