Re: [hobbit] wildcards or regex with SPLITNCV

I'm not using SPLITNCV as I wanted a bit more flexibility in the format of 
the status report (I wanted to have comment line, single colons not 
delimiting values etc.), but am using an external script. You may find my 
earlier reply here
http://www.hswn.dk/hobbiton/2008/10/msg00159.html useful though.

With the external script mechanism you don't need to restart Hobbit if your 
test generates additional indexes, only if you add new tests. I'm not 
entirely sure whether SPLITNCV works the same although it looks OK - but you 
sound perfectly at home with the source, so have a look at that (do_ncv.c). 
If you're interested, I attach my parsing script to the end of this - enter 
the test name list and change the regex for your needs. The commented lines 
were from when I was using a single RRD file for all indices, but that 
doesn't give the flexibility of displaying multiple graphs, or adding 
additional indices.
