Hi all
Searched the list, but never really found anything. Has anybody managed to get iostat data and graphs working for RedHat linux?
Looking to graph the basics for a system for physical disks. r/s, w/s, avgrq-sz, await All the rest is nice to have.
Anybody done this? I'm doing it for aix. I will adapt my script for linux and let you know the result.
For creating and updateing the rrd files, I use the patch from this post: http://www.hswn.dk/hobbiton/2007/01/msg00236.html

VERY NICE, Stef !
I've search long time for such a graph !
By the way, is there a possibilty to added other devices into the graph's .. hope so, think it should be possible, but my script-expertise is not very huge ... :-(
my first shot, change of linux-iostat.pl
< if ( $vmstat =~ /^sd[a-z]/ or $vmstat =~ /^hd[a-z]/ or $vmstat =~ /^md\d/ or $vmstat =~ /^i2o/ ) {
if ( $vmstat =~ /^sd[a-z]/ or $vmstat =~ /^hd[a-z]/ or $vmstat =~ /^md\d/ ) {
doesn't work ..
I've got machines with
Adaptec (formerly DPT) ASR-2010S I2O Zero Channel Controller
which is recognized as
i2o/hda1 i2o/hda3 . .
or
cciss/c0d0p1
by the way, i search also for such a solaris-script ...
Thanks & Cheers,

That's because there is a "/" in it. You can do s/\//_/g in linux-iostat.pl to change the / to _. Or you can strip "i2o/" with s/i2o\///g.
You can do this just before the final command is created (the line where $ENV{BB} is used):
$rrd_return =~ s/i2o\///g ;

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 ....
b)
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) ?
c)
I've got negative KB/s on some y-axis ... hmm, why ?
thanks & cheers

The numbers in the rrd file are fine.
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....
Maybe I can write a howto based on this script... so anyonce can create a graph from a number.

Hi !

.. maybe for you .. :-)
I will update the script and add such feature.
Nice to hear .. thanks !

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 ...

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 !
