Hi, at my company we tend to graph just anything. As long as we were with larrd (written in Perl), we could trick the grapher to accept ever-changing list of data source my making a rrd file for each data, holding one DS per file and looping over patterns. With hobbit, we have a nice NCV semi-automatic way of graphing things. But I want to trend, say, the number of mysql connections per user at host : status databaseserver.int.cvf.sqlcnx green foo at appserver01.int.cvf on content = 2 foo at appserver02.int.cvf on content = 4 statinjector at appserver02.int.cvf on stats = 1 statreader@@backendserver01.int.cvf on stats = 31 bar@@backendserver01.int.cvf on traces = 3 bar@@backendserver02.int.cvf on traces = 4 I can't do it with NCV, because if I add a new appserver03, it won't make have its slot in the rrd file. So I'd like to see something like (S for Split or Single) : SNCV_sqlcnx="/.+ on .+/:GAUGE" that would yield : /usr/hobbit/data/rrd/~$ ls databaseserver.int.cvf/ sqlcnx.foo at appserver01.int.cvf_on_content.rrd sqlcnx.foo at appserver02.int.cvf_on_content.rrd (and so on) Since I really need it, I can always try to add this into hobbit. Would it be possible to implement it as a new channel or it has to be into the code rrd handling ? -- Charles Goyard - cgoyard at cvf.fr - (+33) 1 45 38 01 31
