reading from a log file

[Guest]

I have two usage figures that are written to myfile.log every two hours by a script. I've setup an input source (usage) with the input string 'cat /var/log/myfile.log' and the output string as <rated> <unrated>.

A regular cat /var/log/myfile.log in linux displays the following:
900 1100

Now, it doesn't seem that cacti/rrdtool likes the output of cat. I've created the graph for theabove data source. The legend for the graph displays 900 MB nan 937¥ MB nan. The colours I selected do not appear and yes, that strange character appears

Does anyone have any idea of what going on here?

Seems to me that your cat generates two output values. Your output string definition however indicates that there is only one value <rated>. Try to filter out your cat output to produce only one value or redefine the output string in Cacti - maybe it'll help you.
