The standard report from the clients looks like:

On one client I changed this to:
[iostat]

ENDDATA

to match the sample in the code for do_iostat.c

I also tried the latter with section header [iostatdisk], but none of 
the formats lead to any iostat rrds.
Also no logging of any error can be found. It looks like the rrd-daemon 
doesn't read it, some way or the other.
