Sorry, I said that wrong. I am getting some data in Grafana, but not everything. Array and Cache utilization is populating, as well as CPU and RAM stats. In the top part for setting variables, though, none of my disks are listed when for specifying Flash, Cache, Parity, or Array drives. System temps and power info are not showing. I'm guessing my setup is the issue, though I have read through the instructions a few times. I'll check out the videos, too.
I was hoping the errors I'm getting would be recognizable to someone and there would be straightforward fixes. I'll keep fiddling with stuff.
