I haven't tried this yet, but I think I might have a way. My solution will have to be a bit generalized because I'm not sure what environment you're working with RRDTool in (ie: Perl, shell script, batch files, etc...): 1. Read with the last update of the RRD occurred with the LAST command. 2. Using the date which was read in step 1, read the last with the FETCH command (I think you can use the same start and end time). Store this value in a temporary variable. 3. If you don't have any current data to store in your RRA, store the temporary variable.
OR - a less sophisticated way if unknown values are zero: 1. If you don't have any current data to store in your RRA, store 0 (zero). This is what I do for my Terminal Server usage graphs. Hope this helps.

How can I simulate MRTG´s behavior of repeating the last value seen, so the graphics generated by RRDTOOL won´t have those UNKWN gaps (for missing data)? I am really looking for a "nounknaszero" option, or some kind of fancy CDEF rule to do this. ;-) Is this possible? I´ve tried searching the maillist for this, but I have not suceeded finding threads regarding this matter. Thanks, Henrique. -- 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 -- 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
