Hi Mark, You're missing the module, did you build rrdtool from source or use a RPM/YUM?
To check you can do: updatedb locate RRDs If the perl module is installed you should get something like: /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/RRDs.pm If you find the module but it's not in a perl ISA path you will need to add a line like this to tell perl where the module is: use lib qw( /path/to/RRDs ); I tend to build rrdtool from source per the rrdbuild: http://oss.oetiker.ch/rrdtool/doc/rrdbuild.en.html If you are on centos, you can yum install perl-rrdtool and that should get you want you need. -Chris --- On Wed, 11/4/09, Mark Woodruff <[email protected]> wrote: > From: Mark Woodruff <[email protected]> > Subject: Re: [rrd-users] RRD Newbee needs help with RRD Perl script > To: "Koaps" <[email protected]>, [email protected] > Date: Wednesday, November 4, 2009, 10:52 AM > > Chris, Thank you for the feedback.
