I'm trying to set up opsview (Nagios) on a CentOS 5 server running perl 5.8.9

When I try to start it, it can't find RRDs.pm. Turns out, neither can I. It's not on CPAN and I've been unable to determine what package would provide it. yum provides "*/RRDs.pm" doesn't return any results.

Edit: so we've established that it should come with the perl-rrdtool package, but unfortunately hasn't. Where do I go from here?

RRDs.pm should be provided by perl-rrdtool, but you indicate that you've already installed this program.

Your script can't find RRDs.pm, but RRDs.pm may still be installed on your system, just not in a place where PERL expects to find it.

What do one of these commands tell you?

(You might need to update the locate database first, with /etc/cron.daily/mlocate or a similar cron command)

locate RRDs.pm


find / -type f -name RRDs.pm

I did find an old RRDs.pm in under the perl 5.8.8 libs, but after copying it into the 5.8.9 tree it jsut segfaults. –  Brad Mace Oct 7 '10 at 21:27
I pointed you to the i386 files (I corrected the link). You might have the x86_64 architecture. Make sure you are downloading the correct RPM for your architecture: rpmfind.net/linux/rpm2html/search.php?query=perl-rrdtool –  Stefan Lasiewski Oct 7 '10 at 21:41
CentOS 5.5 ships with Perl 5.8.8 by default. If you are using Perl 5.8.9, then it sounds like you are starting to go the custom route. A simpler solution would be to stick with the default version of Perl, unless you really need a newer version of Perl. –  Stefan Lasiewski Oct 7 '10 at 21:50
This time you've hit it. Running strings against the rpm it appears to be hardcoded to install under perl 5.8.8. I've reverted to 5.8.8 and it's now working! Hopefully there wasn't a good reason I'd upgraded to 5.8.9 –  Brad Mace Oct 7 '10 at 22:26

You have to install rrdtool, CentOS doesn't provide this package by default but you can use Dag Wiers' repository

$ cd /etc/yum.repos.d
$ vim dag.repo

insert the following lines:

name=Dag RPM Repository

and :wq (save) the file. After this, just install the package via yum.

$ yum install rrdtool

Unfortunately I already had rrdtool-1.4.4-1.el5.rf.i386 installed from the CentOS repository, so that's not it either –  Brad Mace Oct 7 '10 at 21:09
