I'm trying to find out the amount of data produced for internal traffic between elasticsearch nodes. Did not find any useful on internet, and i always think that someone have been playing around with this type of questions before.
My setup: helm install from bitnami.
My analys that i did was to monitor the networkinterface for each vxlan-calio with wireshark.
and the end result was a bit higher then i expected.
during a 24H cycle in an idle system the data produced around 7gb. (no data written to shard etc)
The problem that i'm facing is that i will create a remote cluster with 4g/5g communications between nodes. And the overhead that i'm facing is bit to high to make is worth it.
