stdlib.localLogStash - How to get mined data into logstash

[HKcyberstark]

Hello Team,

I have set up few IP miners and then processing through a inbound aggregator and then giving it to Logstash output,

Names have been customised as I have cloned the aggregator and output from existing prototypes.

I am not seeing any indicators in DARP-output [stdlib.localLogStash] . is it normal ? and can some one help me with logstash configuration for getting these indicators into a file.

i tried this but no success. dont know what i am missing. kind help is much appreciated.
#logstash configuration:
input {
tcp {
port => 5514
}
}

output {
file {
path =>/etc/logstash/minemeld-output.txt
}
}
