}now the box takes along time to respond to me over ssh.

What }memory/cpu is }really needed to do this kind of monitoring ? A 450MHz x86 box will be pretty slow at generating graphs. I try to avoid anything less than 1GHz (x86) when building a system that will be doing dynamic graph generation. If you want to stick with this hardware and won't be adding very many targets, then you may want to abandon RRDtool mode and use the old logfile-style system with rateup (I can't believe I said that). Before you do that, you may want to try 14all.cgi, it probably won't make a speed difference, but it's worth a shot if your only alternative is logfile mode.
My suggestion would be to find a faster system to run it on, or at least to run the mrtg-rrd.cgi script on (you could nfs mount the .rrd directories if you _really_ want to use the 450MHz system as a poller-only-box). In my experience, MRTG with dynanmic graph generation coexists quite nicely with other applications on the same server. For instance, take my system at http://mrtg.gvolk.com. Click on Switch -> All Targets. It'll spit out 28 index graphs in about 10 seconds. That system also handles the following applications: two apache instances, sendmail, two snort IDS processes, NAT (for a small network), smbd/nmbd, dnrd, and mysqld. It's a 1.5GHz Athlon with a half gig of memory and some cheap IDE disks. -- Attached file removed by Ecartis and put at URL below -- -- Type: application/ms-tnef -- Size: 1k (1919 bytes) -- URL : http://www.ee.ethz.ch/~slist/p/68-WINMAIL.DAT -- Unsubscribe mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/mrtg FAQ http://faq.mrtg.org Homepage http://www.mrtg.org WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
