OK, I must've been reading too fast. Suppose you have a DS:n:COUNTER, and a CDEF:hot that is either 0 (<=24) or 1 (>24), maybe you can make a CDEF:nhot that is average(hot)*(n-PREV(n))? -- Grtz, Ruud -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-developers WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
