My guess is that the problem is a combination of:
a) some paths being specified using / as the separator and some using \
b) some paths being absolute (starting with \ or /) and some being relative
(not starting with \ or /)
c) the fact that you’re on a Windows system and most of the documentation
assumes Linux.
So, as a starting point, try making all the paths consistent - use / as the
separator throughout, with no instances of , and also make them all relative
(ie: remove any / at the start of the path name).
If that doesn’t work, try making all paths absolute (ie: starting with
C:/Grafana/…) and see if that gets you any further.
