Well, sort of not really. The thing is, I could definitely do half of what I needed to do with a PRINT statement, but if I want to do anything with that return value, I need to trap STDOUT (I'm working in Perl, btw), and then read the value in, etc. The other major caveat is that I don't really want to generate the graph, I just want the data results. What I'd really like is to be able to get a data return like RRD fetch gives you, but rather than getting a table/listing of DS values at each interval, get a listing of DEF and CDEF values at each interval, as well as be able to get AVG, MIN, MAX, etc. Basically, I want fetch-like capabilities on data generated by graph-like arguments. * Philip Molter * DataFoundry.net * http://www.datafoundry.net/ * [EMAIL PROTECTED] -- 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
