Hi,

Can I configure logstash to set "source IP address" as index ? Is there any variable for that?

If there is a field containing the source IP then you can use a sprintf reference in the index option. It is documented [here](https://www.elastic.co/guide/en/logstash/current/event-dependent-configuration.html).
