Hello guys!

I'm trying to use if condition in the elasticsearch section.  
I want to write to different indexes depending on ip. what's wrong? 😟

```
elasticsearch{
if [node_ip] == "10.6.108.100" or "10.6.108.101"
{ 
index => "node1-%{+YYYY.MM.dd}"
hosts = > ["elasticsearchhost:9200"]
}
else if [node_ip] == "10.6.108.102" or "10.6.108.103"
{ 
index => "node2-%{+YYYY.MM.dd}"
hosts = > ["elasticsearchhost:9200"]
}}
```

You can not use conditionals within a plugin. Instead create multiple elasticsearch plugins with the correct config within conditionals.

Another option is to set a field that holds the prefix based on the conditionals and then use this in the index name specification within a single Elasticsearch output plugin.
