"io/console not supported; tty will not be manipulated" msg

Elastic Stack Logstash
1

Hello,

I run LS on SLES12 of s390 and get this msg as follows:
" bin/logstash -e 'input { stdin { } } output { stdout { codec => rubydebug } }'
io/console not supported; tty will not be manipulated
Logstash startup completed "

But if run LS on SLES12 of X86, no such a msg displayed:
" bin/logstash -e 'input { stdin { } } output { stdout { codec => rubydebug } }'
Logstash startup completed "

My question is what this ms g mean and why LS behaves different on platforms
even though Linux is the same

Thanks,

Sam

Linux might look like it's doing the same thing but you're running on completely different hardware architectures and under the hood, everything is different :smile:

We certainly don't officially support anything other than physical/virtual x86 architecture. The error you are getting sounds more like a JRuby problem than Logstash, it might be worth asking within the JRuby community for help.
