[mrtg] MRTG Script error ... Now Slightly OT

[Martin Rheumer]

I actually tried this out.. ( with the corrected paths ). On a Fedora
Core 7 / 8 machine it produces the same output every time I run it.

Has anyone actually tried to use the iostat and got some results from
it and could perhaps shed some light on what I have done wrong.

(wally)[/usr/local/bin]root# ./diskio.sh
7670
4114
(wally)[/usr/local/bin]root# ./diskio.sh
7670
4114
(wally)[/usr/local/bin]root# ./diskio.sh
7670
4114
(wally)[/usr/local/bin]root# ./diskio.sh
7670
4114

Even waiting 12 hours gives the same results ?

Thanks
Martin
