I have just installed RabbitMQ, I'm using it with logstash. I have been sending messages but I lose a lot of data. I have no idea how could I solve it. I'm using the default configuration in rabbitMQ.

These are the output in logstash and the input in logstash:

output {  
rabbitmq {  
host =\> "IPHOST"  
exchange =\> "logstash-rabbitmq"  
exchange\_type =\> "direct"  
key =\> "logstash-key"  
workers =\>4  
durable =\> true  
persistent =\> true  
}  
}

input  
{

rabbitmq {  
host =\> "IPHOST"  
queue =\> "logstash-queue"  
durable =\> true  
key =\> "logstash-key"  
threads =\> 8  
prefetch\_count =\> 100  
port =\> 5672  
user =\> "test"  
password =\> "test"  
ack =\> false  
exchange =\> "logstash-rabbitmq"  
}

}  
I'm using RabbitMQ Management in order to see the evolution of my queue. When I send 10000 messages I only receive less than a half. Is there any parameter I should change to imporve the behaviour of rabbitMQ? I was going to use it in order to don't loose messages but I'm loosing even more than when I didn't have it.

thank you
