[rrd-users] Re: Getting last value out

[McCann, Brian]

I'm trying to avoid Perl...I'm not, nor have I ever been, a big fan of
it.  But...that's a huge help.  Thanks!

You can run a RRDTool last some.rrd to get the last update time.  You
can then turn this around to make your RRDTool fetch.

-or-
my $rrd = '/some/database.rrd';
my $last = RRDs::last($rrd);

Then you would use $last as the time to fetch (I'm fuzzy on the Perl
Shared fetch arguments but if you're already doing it, I'm sure it won't
be that hard).

This is such a simple question I must be missing something stupid.  I'm
trying to get the last value of a DS out of an RRD, but for the life of
me can't figure out how.  I figured that "rrdtool fetch" would do
it...but when I specify LAST, I get an error.  I read the man page, and
was a little enlightened, but not much.  Any help would be appreciated.
 
Thanks all.
