I chekced in /mnt/dietpi_userdata/grafana but I cant find conf directory underneath it !
please help me locate where is grafana directory located.
Yeah /mnt/dietpi_userdata/grafana is symlink target for /var/lib/grafana only, where internal database and plugins are stored. The config file is in /etc/grafana. I think we should link this to userdata as well to have everything in one place, do you agree?
I am anyway just reworking the Grafana installer a bid due to outdated repo on ARMv6 systems, so good time to suggest some enhancements 
.
can you guys help me with setting up smtp email in grafana config or do I have to speak to grafana peepz on their website ?
