env: es 6.2 + kibana 6.2
There are 5 hosts.Every 2 minute,the value of network bandwidth indexing to es by each host.For example：
host A.net_bandwidth: 200
host B.net_bandwidth: 400
The unit of measurement is "KB/s"
How can I visualize the total bandwidth of 5 hosts in time series? Approximate value is ok.
If i choose sum aggregation to do this, when the time interval greater than 2m,the result is far greater than actual value.
Thinks for your help.
