Hi,

We have logstash 5.2 installed on a server which doesn't have internet access. We want to install the logstash-codec-protobuf plugin. We don't even have a staging server with internet access. So using 'Offline Plugin Management' is also not an option.

Is there any other way by which I can install logstash-codec-protobuf on a complete offline machine?

I tried to install rubygems and ruby-protocol-buffers, but still there is version compatibility error during logstash-codec-protobuf installation. Does anyone have some Idea about what is wrong here?
