Why not use RRA zero as in rrd_first when no RRA index is given? > Example: what > if no resolution is mentioned, Then do like rrd_fetch and use a resolution of one. > what if an existing resolution is > mentioned, Then set the step value to that unless it's less than one.

Again, do like rrd_fetch and attempt to find the best match. > You also say: "I'm only interested in knowing the oldest time stamp"... Let me clarify. I would like to add a new token to SpecialToken called "begin" or "first" that will allow the user to specify that they would like processing to begin with the oldest time. I would like the patch to work with rrd_fetch, rrd_graph,rrd_xport, etc. To do this, it seems that the changes would have to be made to parsetime.c; however, parsetime doesn't have all the necessary information (e.g., the RRD file, which CF, etc.), so things might have to be handled elsewhere. > So, similar to "rrdtool last", you are proposing "rrdtool first". I am proposing a new special word that can be used as a start time; it will be equated to the same time as that returned by rrd_first. Perhaps we should move this discussion to the developer's list. -- Regards, Travis Spencer _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
