Edit: first test-version is here
I played around a bit with displaying SMART graphs in OMV and ended up with this:
This graphs have a 30 min interval and show "hourly" changes, but I think daily is enough for SMART.
and: the colors are randomly generated so don't slapme for this
ToDo:
- align the values
- maybe change the UUIDs to the OMV-names of the HDDs
Do you want to have something like that in OMV?
