I can well believe that; SNMP seems to display an infinite number of variables. However, all the examples I've seen are actually looking at variables available from /proc or iptables, and it just struck me that the additional complication of setting up snmp made the whole rrd thing absurdly complicated (ie I haven't succeeded in getting it working!) It just struck me that snmp + rrd might be something that administrators of large systems had got into the habit of using, which might actually not make sense any longer. But as I said, I don't really know what I am talking about ... -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
