I've setup elastiflow on my ELK Stack to serve as a netflow collector, but I noticed visualizations showed different data to what I expected, then I realized kibana was using `flow.client_hostname` index pattern as the field to show the data, when what I expected to use was `flow.src_hostname`.

I've change the fields used in the graphs, but I'm really curious what would be the difference between `flow.client_hostname` and `flow.src_hostname` .

I expect the source IP address from that particular flow to be the "client" in that conversation, if thats not the case what's the logic behind this fields "flow.client\_hostname/flow.server\_hostname/flow.autonomous\_system".

I've checked on Management section but all I can find is that these indexes are String.

I am going to move this to the Logstash topic - someone there should be able to describe the difference between `flow.client_hostname` and `flow.src_hostname`

@gsantiago please open an issue and ask this question on the [**ElastiFlow**](https://github.com/robcowart/elastiflow) repository and I will answer it there.
