I started to use Munin for monitoring, but I want to change colors of the graph, which are drawn by it's 'loggrep' plugin.
Is there any way to specify colors in the config file?
fieldname.colour RRGGBB (take care to use the British English notation of "colour" here) in the
config part of your plugin's output to define a specific color for the graphical representation.
