Logstash expected one of #

Question

I'm currently trying to run Lostash with the following config file:

input { 
    stdin { } 
} 
output { 
    rabbitmq { 
        exchange => "test_exchange" 
        exchange_type => "fanout" 
        host => "172.17.x.x" 
    } 
}

I do however get an error:

logstash agent --configtest -f -config.conf

gives me:

Error: Expected one of #, } at line 1, column 105 (byte 105) after output { rabbitmq { exchange => test_exchange exchange_type => fanout host => 172.17

It seems that logstash has the problem when I put an IP-like address in the host field. What is wrong with my config?

You probably have some garbage character at the end of your file (or wherever offset 105 ends up). If I copy the config file snippet above into a new file Logstash is happy with it. Feeding your file to hexdump -C should make the mistake easy to spot. — Magnus Bäck
Nop, I still have the same problem, even after having recreated the file from scratch or used the -e option. — Heschoon
Okay, seems that it had something to do with the way I created the config.conf; I was using an echo "content" > config.conf, but the problem is that I surround a text containing double quotes with double quotes... Surrounding the contents by single quotes when creating the config.conf file did solve my problem. — Heschoon

The whole problem was in the method you used when created the config.conf file.

You were using the following command:

echo "input {stdin{}} output{rabbitmq{exchange=>"test_exchange" exchange_type =>"fanout" host=>"172.17.x.x"}}"

Surrounding a string containing double quotes with double quotes isn't a good idea...

By using single quotes around the string, the problem is solved...

echo 'input {stdin{}} output{rabbitmq{exchange=>"test_exchange" exchange_type =>"fanout" host=>"172.17.x.x"}}'
