Hi,
we have about 56 lxd units monitored using telegraf charm. There is a relation setup with influxdb. All the units failed upgrading to the latest rev(43).
looking at the logs it is related to the influxdb-api.conf but i can't seem to sort it out :)
Any help would be really appreciated.

This issue was pending long time. Is it still valid?
Furthermore, soon or later, the monitoring system will migrate to COS. Telegraf will be replaced by grafana-agent. Therefore, we won't follow up this issue. But welcome to reopen it when anyone encounter this issue again.
