Index and id tag to my log stash config

[Milton_Sam_Moses]

Hello, Exerts

I have a logstash config with works well. Just need your advice to auto creat index and id to the output file.

Config:

input {
file {
path => "/tmp/sam"
}
}

output {
file {
path => "/tmp/sam_output"
}
}

current Output :
mmoses@dev-platops-eng02:/opt/logstash/bin$ echo "Hello World" > /tmp/sam; tail -f /tmp/sam_output
{"message":"Hello World","@version":"1","@timestamp":"2017-09-15T18:25:51.082Z","host":"dev-platops-eng02.kendall.corp","path":"/tmp/sam"}
{"message":"Hello World","@version":"1","@timestamp":"2017-09-15T18:25:51.721Z","host":"dev-platops-eng02.kendall","path":"/tmp/sam"}

desired output
mmoses@dev-platops-eng02:/opt/logstash/bin$ echo "Hello World" > /tmp/sam; tail -f /tmp/sam_output
{"index":{"_index":"helloworld","_type":"date","_id":0}}
{"message":"Hello World","@version":"1","@timestamp":"2017-09-15T18:25:51.082Z","host":"dev-platops-eng02.kendall.corp","path":"/tmp/sam"}
{"index":{"_index":"helloworld","_type":"date","_id":0}}
{"message":"Hello World","@version":"1","@timestamp":"2017-09-15T18:25:51.721Z","host":"dev-platops-eng02.kendall.corp","path":"/tmp/sam"}

Use a mutate filter and its add_field option to add the fields you want. See https://www.elastic.co/guide/en/logstash/current/event-dependent-configuration.html#logstash-config-field-references for more on the syntax you should use for nested fields.
