I am currently using collectd to collect statistic on about 100 hosts, for it I 
wrote my owner grapher. So far we have only run i686 and amd in 32bit and 
things have not been a problem. Collectd allows to run over the network but so 
far everytime I looked at it, I lost too many packets and so I got holes in the 
data. Because of that we run collectd local on each box and copy every 30 
minutes the rrd files to the grapher box. This works good enough for us as long 
we ran only i686. But we also got 3 Solaris sparc machines now and x86_64 is 
our new target for Database servers. 
 
And here lies the problem. The format of the rrd file is depend on the platform 
is was written on, you can only xml dump it there and then reimport on the 
grapher box, not very elegant nor efficent, esp. when you are start getting to 
larger number of machines. I really would like to see if there couldn't be 
support for (as option maybe) of allowing platform independ files. I know of a 
friend at Yahoo, who uses rrdtool also and has run into the same problem much 
more so then I have.
 
Lets discuss please.
 
Ulf.
