Disable encryption for grafana live

as there is no documentation other than it is the influx line protocol for grafana live i want to see the packets send by telegraf via tcpdump. However, as the websocket connection is encrypted (does not make sense as telegraf and grafana are running on the same host) i can not see what is send by telegraf to grafana.
How can i disable encryption for the websocket ?


Mainly to figure out if i have to send a full http put including authentication for every post on a persistent connection using libcurl.
