Hmmm. That's interesting.
So, nothing is getting to the rrd file for the rrd graphing module to read.
Have you checked that the values are being sent through correctly? By this, I mean, when it exceeds 100%, is your script still sending data correctly? Do you have some code somewhere in your script that sends non-numeric output at 100 or over? Think in terms of what changes at 100 or above? You have moved from 2 characters to 3. Also, has the input to your script changes in some subtle way at 100%, which will change the output. Remember, for NCV to work, the output has to be fieldname : value on a line on their own. Any garbage will break it. Check especially for non-printable characters and control codes. Dump your output to a file, and use cat -v

Hello,
Thank you for the quick response. I checked the rrd data and it seems that no data is being written to the file when it exceeds 100%. Any idea where the problem could be located and how to fix it?
As I said below 100% it writes fine, so I’m guessing that it’s not the format that is sent to Xymon, but how rrd reads it?

First check the values in the rrd file. Make sure they are being written to the data file.
Next, check hobbitgraphs.cfg Your graph definition probably has -l 0 -u 100 Lower bound 0 Upper bound 100
Remove the -u 100, and the graph will automatically rescale itselft to the new data values.

Hello,
I have an issue with a custom memory script I wrote. The script delivers everything fine and also the data is processed correctly in Xymon, but when the data goes above 100%, which it can, no more graphs are created. When it drops graphs are ok again. Does anyone know where/how exactly I need to modify the rrd so it accepts above 100% to create the graphs.
Thx in advance
