Hi !
Of course, the script was more a proof of concept. I had the iostat numbers on aix, so it was not that hard to change it for linux.
.. maybe for you .. :-)
I will update the script and add such feature.
Nice to hear .. thanks !
I've got three empty links in the trend=page to iostat-disk, how could i delete them or is there a association with a) ? Euh, can you upload the graph somewhere so I can see it ?
Not really important, maybe my own false configuration, i will answer again, if i've checked it again ...
Writes are negative, reads are positive. This is defined in the hobbit-graph.
Right, it's plausible and documented, thanks ...
I just saw in my script and it also collects the statistics in blocks per second. And by combining the blocks and bytes / second you can get the block size. I can add such graph definitions if anyone is interested....
Yep, my vote, you have ... :-)
Maybe I can write a howto based on this script... so anyonce can create a graph from a number.
I think this will be great !
Cheers & thanks again !

Great Stuff, Stef !
... three more questions,
a) is it possible to declare some excludes or something for only active-disks ?
e.g. md0 , the most of my machines have not software-mirror but some .....
or
/dev/hdd or /dev/cdrom .. in my graph's it appears as hdd but that's the cdrom and it's empty .... Of course, the script was more a proof of concept. I had the iostat numbers on aix, so it was not that hard to change it for linux. I will update the script and add such feature.
b)

I've got negative KB/s on some y-axis ... hmm, why ? Writes are negative, reads are positive. This is defined in the hobbit-graph. The numbers in the rrd file are fine.
