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](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.
