Installing n2rrd with Nagios on Centos 6.2

[Randal, Phil]

Can't help but think that using pnp4nagios would be easier :-)

Subject: [Nagios-users] Installing n2rrd with Nagios on Centos 6.2

I am in the process of building a Centos 6.2 system to run Nagios and n2rrd.  It is a virtual machine / sandbox.  Centos 6.2 is installed as is Nagios 3.4.1 and Nagios Plugins 1.4.15.  Nagios and the Nagios Plugins were installed following the Fedora Quick Start instructions at
http://nagios.sourceforge.net/docs/3_0/quickstart-fedora.html   Nagios was
started and I was able to access the Nagios web pages on Apache successfully.
It is the basic, just after installation, configuration, but it tells me it is working.

The next step was to download and install n2rrd.  I downloaded nagios-n2rrd- 1.4.5-1.src.rpm, and started following the instructions at http://n2rrd- wiki.diglinks.com/display/n2rrd/RPM+Source to perform the install.

Step 2 rpm -i nagios-n2rrd-1.4.5-1.src.rpm created /root/rpmbuild/SPECS, SOURCES, etc.

Step3 and 4 verify the PATHs for ../SPECS/n2rrd.spec and ../SOURCES/...

Step 5 executes the rpmbuild -ba  /root/rpmbuild/SPECS/n2rrd.spec

My first attempt at rpmbuild revealed that I had some problems with some PATHs specified in n2rrd.spec.  Nagios is installed entirely in /usr/local/nagios.
No problem, now that I know.  I made the appropriate (I believe) changes to
n2rrd.spec:

#nagios related
%define         nagios_conf_dir   /usr/local/nagios/etc
%define         nagios_data_dir   /usr/local/nagios/share
%define         nagios_lib_dir    /usr/local/nagios
%define         nagios_log_dir    /usr/local/nagios/var

I'll admit I guessed on the nagios_lib_dir.  I fired up a Nagios installation I had on Fedora 14 to compare directory structures and defining it as /usr/local /nagios did not seem unreasonable.

I kicked off the rpmbuild -ba  /root/rpmbuild/SPECS/n2rrd.spec again and the messages look a bit better.  Near the end of the output, I am seeing the
following:

Processing files: nagios-n2rrd-1.4.5-1.noarch
Provides: config(nagios-n2rrd) = 1.4.5-1
Requires(interp): /bin/sh
Requires(rpmlib): rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(FileDigests) <=
4.6.0-1

Processing files: nagios-n2rrd-rrd2graph-1.4.5-1.noarch

/BUILDROOT/nagios-n2rrd-1.4.5-1.i386

I believe the above messages are statements produced by the execution rather than errors.  These statements are followed by some errors:

error: Installed (but unpackaged) file(s) found:
   /etc/nagios/n2rrd.cfg
   /usr/share/nagios/css3menu/256base-save-over.png
   /usr/share/nagios/css3menu/256subdown.png
   /usr/share/nagios/css3menu/256subdown1.png
   /usr/share/nagios/css3menu/EPS.png
     .
     .
     .
   /usr/share/nagios/css3menu/zoom-graph.png
   /usr/share/nagios/css3menu/zoom.png


RPM build errors:
    Installed (but unpackaged) file(s) found:
   /etc/nagios/n2rrd.cfg
   /usr/share/nagios/css3menu/256base-save-over.png
   /usr/share/nagios/css3menu/256subdown.png
     .
     .
     .
   /usr/share/nagios/css3menu/zoom-graph.png
   /usr/share/nagios/css3menu/zoom.png


My questions are:

1 - Can someone confirm the above messages  (Requires...) are statements rather
    than errors?

2 - What did I do wrong to generate the 'Installed (but unpackaged) file(s)
    found:' errors?

3 - Is there some 'big picture' item or bit of knowledge that I am missing that
    caused me to make these errors?

Yes, I am beyond the limit of my expertise here.  Any thoughts or comments would be welcomed, even 'this is the wrong place for this message.'

Thank you.
