I've installed Graylog v2.1.1 as a virtual appliance inside VirtualBox on a Windows 7 PC.
I'm trying to read a simple log file and forward it to Graylog by using logstash v5.0.0 with the logstash-output-gelf-3.1.1 plugin, as described here: https://stackoverflow.com/a/31054064/4863804.
I've set up the following logstash.conf output:
input {
file {...}
}
output {
gelf {
host => "199.99.99.179"
port => 12203
}
}
But after running logstash -f logstash.conf I get the following error:
[2016-10-28T14:52:17,756][INFO ][logstash.pipeline ] Pipeline main started
