Hello everybody, Two weeks ago I posted a mail regarding graphs that stays empty when importing values. At that time when I checked the log-file for the graph, all values was on the first line in the log file, the rest was zeroes. (The mail I posted is below).
Now I have found what the problem was. It seems that MRTG can not handle the big values that I imported. For example, monitoring one of my harddrives with freespace.exe gives me the following output 13030923264 120031478272 n/a d: First line is free space and second is total space, ie about 13 GB free of about 120 GB. I had this running for two weeks (producing empty graphs) without changing anything. When I almost ran out of disk space the other day the graph suddenly started to appear (when around 2 GB free space). Later, when I made more space available, the problem returned (the graph does not update although the correct value - 13030923264 - is at the first line in the .log-file. (The value stays at the first line all the time). >From what I understand this must be a problem in MRTG and not the .cfg-file. I have tried several different option in the .cfg-file including setting the MaxByte option a lot higher.
