Thx, Clifton and Owen for the info, I didn't knew this was possible, however I'm unsure howto implement this with my current setup, using the latest mrtg & rrd versions, I'm using mrtg config files with the 'LogFormat: rrdtool' entry, the target names do reflect the .rrd file names. Is there somewhere an example config file, that shows how this gets setup? I'm going to use hardware RAID1/U-160 SCSI, but getting all data from one machine in one .rrd file would really improve the performance. On the other side I'm running apache & mod_perl on the machine, I tried RRDGrapher.cgi, but it can't create dynamic .png, the docs say that it wouldn't work with mod_perl. Creating pictures from multiple .rrd is not a problem, as long as I run rrdtool from cron, generating a few pictures.
