Something like this can be implemented pretty easily in perl, by fetching out the values you want to compare. You can also craft a CDEF to do the math for you, and use "rrdtool xport" to show you the value. A CDEF that checks DEF "a" for this would look something like: CDEF:alert=a,PREV,a,2,*,GT,1,0,IF Aaron Spiegel -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
