Is there any logs that can help debug influx export? I looked at the librenms container but nothing is there.
I can send data with curl from Librenms but the device data is not being sent to influx. I have a live tcpdump listening on influxdb server but I only see the curl command that I do. I am running librenms 21.4 on docker.
What version of influx are you running?
try tcpdump on your libre host to see if anything is getting exported
Also note that if you are using remote pollers, these individually export their data to Influx so will need appropriate firewall rules in place
