Openbsd, telegraf and influxdb v2 : cpu reporting issue

Telegraf
1

Hi there,

just getting acquainted with influxdb and telegraf to replace a collectd, rrd and CGP stack.

i use an influxdb v2 docker container (on a debian system) and installed several telegraf on the different machines.

on openbsd i installed telegraf via “ports”, therefore it is telegraf-1.13.4p2

I’m having an issue where the CPU reported is wrong
The graph from the UI shows a lot of CPU use (see screen cap):
influxdbUI_openbsd

while on cli with vmstat it show almost 0 usage :
