Is there any way I can get the IP address of the logstash node within metric plugin? my code is like this --

filter {  
metrics {  
meter =\> "events"  
add\_tag =\> "metric"  
}  
}

output {  
if "metric" in [tags] {  
elasticsearch {  
host =\> "10.207.96.20"  
index =\> "metrics"  
document\_id =\> "mydoc\_\_id"  
}  
}  
}

And the output I get from Elasticsearch is like this --

{  
"took": 1,  
"timed\_out": false,  
"\_shards": {  
"total": 5,  
"successful": 5,  
"failed": 0  
},  
"hits": {  
"total": 1,  
"max\_score": 1,  
"hits": [  
{  
"\_index": "metrics",  
"\_type": "logs",  
"\_id": "mydoc\_\_id",  
"\_score": 1,  
"\_source": {  
"@version": "1",  
"@timestamp": "2015-10-05T06:39:16.204Z",  
"message": "[LogConcentrator.juniper.net](http://LogConcentrator.juniper.net)",  
"events.count": 16614,  
"events.rate\_1m": 119.04031830447626,  
"events.rate\_5m": 28.09862951056484,  
"events.rate\_15m": 12.343469930579069,  
"tags": [  
"metric"  
]  
}  
}  
]  
}  
}

Here the message field returns the Hostname but I need the corresponding IP address. Is there a way to get it?

The [dns filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-dns.html) can resolve hostnames to IP addresses.
