Today you sent me mail regarding [rrd-developers] opposite of unknaszero: *> Hi! *> *> [I'm not sure if rrd-developers is the right place but I think I'll reach *> the right persons and there is more traffic on rrd-users ;-) ] *> *> Some time ago there was a thread about how get the "unknaszero" semantics *> with rrdtool (to stack some values). Now I wonder if I could get the *> "opposite" behaviour as known from mrtg. I'll explain: *> *> The goal: *> mrtg repeats the last value from the log for following unknown values. You *> can suppress this with "Options[..]: unknaszero". As I try to simulate mrtg *> with 14all (btw: thx alex for promoting it so much ;-) I would like to get *> the first behaviour too (the second is trivial with rrdtool). *> *> The problem: *> I don't know a way to do this with rrdtool. *> I didn't found an option like "unknaslast" ... *> I wanted to try "ds0,UN,last(ds0),ds0,IF" but there's no such function.
there is a function in the fix patch to 1.0.7 which lets you access the previouse value of an datasource ... will be properly released in 1.0.8 cheers tobi *> Any ideas? It think it's hard to realize (make the stack "persistent" to *> save the last value on it, a second stack to push old values on ...) *> *> *> Rainer *> -- ______ __ _ /_ __/_ / / (_) Oetiker, Timelord & SysMgr @ EE-Dept ETH-Zurich / // _ \/ _ \/ / TEL: +41(0)1-6325286 FAX:...1517 ICQ: 10419518 /_/ \.__/_.__/_/ [EMAIL PROTECTED] http://ee-staff.ethz.ch/~oetiker -- * To unsubscribe from the rrd-developers mailing list, send a message with the subject: unsubscribe to [EMAIL PROTECTED]
