i use telegraph to send data to grafana.net influxdb proxy for this purpose, name_prefix help to identify data in grafana. for now i edit config file /usr/local/etc/telegraf.conf and add : nameprefix = "OpnSense" in [[outputs.influxdb]] section

but every day at midnight this config file is replaced by the datas from opnsense gui which not contain name_prefix.

Describe the solution you'd like

is it possible to addname_prefix field in telegraf output influxdb config ?

Describe alternatives you've considered editing config file /usr/local/etc/telegraf.conf
