Re: [hobbit] iostat

Hi Stef,

It works ... i'm now seeing mount points in my iostat graphs.  But, how 
will I add this "disk iostat"  in metrics reports instead of in trends 
column. 
Actually, we are submitting server performance graphs in a weekly basis.

Thanks a lot,


RaAL

sda1 is my / fs, so I create a symbolic link:
ln -s iostat-part.sda1.rrd iostat-part-mp,root.rrd

sdb5 is my /home/users fs, so I create a symbolic link:
ln -s iostat-part.sdb5.rrd iostat-part-mp,home,users.rrd

Added to hobbitgraph (copied from [iostat-part], only the FNXPATTERN is 
changed):
