Today you sent me mail regarding [rrd-developers] New DEF: virtual def: *> No, no code yet. *> *> I was wondering about the resolution of the data inside a CDEF. *> Doing functions with TIME, it will not be at the picture resolution, *> it will be at the data resolution.
yes ... I guess the 1.1 series will have to have a syntax for defining data density ... in the grapher options ... cheers tobi *> *> Try it: create a RRA with CDPs every two hours. Now use the TIME *> function inside a CDEF and mask out every other half hour: *> *> DEF:mydata=some.rrd:..... *> CDEF:mask=TIME,3600,%,1800,LT,mydata,UNKN,IF *> *> It won't work as intended, the resolution of the data is too low. *> *> Perhaps we could use something like "VDEF" that carries no data in *> it but can be used for time related stuff. It would have a resolution *> of one calculation per pixel. I'm thinking of: *> *> DEF=mydata=some.rrd.... *> VDEF:thetime=TIME *> CDEF:mask=thetime,3600,%,1800,LT,mydata,UNKN,IF *> *> Also, there would be no restriction to always use a DEF or CDEF in it *> and the following is completely legal: *> *> VDEF:constant=20 *> *> as opposed to *> *> CDEF:constant=data,POP,20 *> *> *> Comments ? *> *> Regards, *> Alex *> *> -- *> * To unsubscribe from the rrd-developers mailing list, send a message with the *> subject: unsubscribe to [EMAIL PROTECTED] *> *> -- ______ __ _ /_ __/_ / / (_) 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]
