Nagios Grapher fun
I was struggling with Nagios Grapher (or was it nagiosgraph - I tested both) in Slackware 13.1 After installing all dependencies it would still refuse to work. I tracked the problem pretty easy to be related to Perl not being able to load the librrd.so.4 library.
That was funny as I was sure that I did configure, make and make install the latest version. Well, by default, on slackware at least rrdtool installs in /opt !
I added /opt/rrdtool-x.x/lib in /etc/ld.so.conf (check to see what is the exact path in your case) and re-ran ldconfig. Sure enough everything worked fine.
This is the error log I received:
