The config file:
# input are the kafka messages
input
{
kafka
{
topic_id => 'test2'
}
}
# Try to match sensor info
filter
{
json { source => "message"}
}
# StatsD and stdout output
output
{
stdout

format => "%{[testmessage][0][key]}"
}
}
stdout { codec=>rubydebug }
statsd
{
host => "localhost"
port => 8125
increment => ["test.%{[testmessage][0][key]}"]
}
}
Input kafka message:
{"testmessage":[{"key":"key-1234"}]}
Output:
key-1234
{
"testmessage" => [
[0] {
"key" => "key-1234"
}
],
"@version" => "1",
"@timestamp" => "2015-11-09T20:11:52.374Z"

Very wired why statsd does not work in my logstash. Looking into lots of examples by Google, no idea why. Any suggestions are welcome. Thanks.
