Failing to pass data point to influxdb

Telegraf
,

I just setup influxdb using the ocker container behind a nginx reverse proxy without TLS:

# insecure, do not use like this!
server {

	listen 8086;
	listen [::]:8086;
        server_name influx.some.where;
		
        location / {
			proxy_pass http://influx;
			proxy_redirect off;
			proxy_http_version 1.1;
			proxy_max_temp_file_size 10m;
			proxy_connect_timeout 20;
			proxy_send_timeout 20;
			proxy_read_timeout 20;
			proxy_set_header   Host		$host;
			proxy_set_header X-Real-IP $remote_addr;
			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
			proxy_set_header X-Forwarded-Proto $scheme;
			proxy_set_header X-Original-For $proxy_add_x_forwarded_for;
			proxy_set_header X-Original-Proto $scheme;
			proxy_cache_bypass $http_upgrade;
        }

}

Using telegraf on Fedora I see tons of those messages every time an update is supposed to be pushed to influx db.

I think you don’t have support for uint values in InfluxDB, but it is enabled in Telegraf. This option is not enabled in the official InfluxDB packages and is a compile time flag, you will either need to compile InfluxDB with this setting enabled, or set influx_uint_support = false in Telegraf.
