I had configured a data collection item of "used disk space percentage " with parameter: Disk.FreePerc(/dev/hda1) . It shows up as 46 % when it is actually 3 % .I have seen that it shows the same value for all other partions . I have tried this on linux redhat 3 enterprise and fedora 5 . It gives me wrong values . Is this because my operating systems redhat 3 and fedora 5 are too old ?
Will this be resolved if i upgrade my OS ?
Try to use mount point name instead of device name.
Update: it looks like a bug, i just reproduced it on fresh Ubuntu.
thank you , it works now . i used mount points instead of filesystem paths .
the values of "percentage of used disk" are not exact there is atleast 6% difference
