I am running ELK setup on a single machine. Everything was working fine
untill I switched off my internet connection.
My logstash console shows this error when I switch off Internet connection:
log4j, [2014-11-27T10:31:57.480] WARN:

***EDIT***
Logstash output config:
output {
elasticsearch { host => localhost }
stdout { codec => rubydebug }
}
So it seams it's unable to connect to ES server.
So is an internet connection be required always?? I am new to the setup.
