Monitoring tool - init script for icinga, ido2db(idoutils), and npcd(pnp4nagios)

As installing finishes icinga, icinga-web, and pnp4nagios, it's necessary to setup init scripts to run and stop daemon. Of course, each of the source files includes ones, but I prefer a typical format based on RPM package to the ones in the source file. So I modified the init scripts based on RPM packages.

I am going to introduce of each of the init scripts and verification about how they work.
They are open to the public in my github.

daemon and init script

Icinga (based on Nagios RPM package)	/etc/init.d/icinga
IDOUtils ( based on NDOUtils RPM package)	/etc/init.d/ido2mod
PNP4nagios ( based on Nagios RPM Package a little)	/etc/init.d/npcd

icinga

create init script based on nagios RPM package

about the pidfile and the lockfile path
Icinga.cfg(also nagios.cfg) defines lockfile as pidfile.
I'm not sure why they're defined as so, but I think they should be separated.

Monitoring tool - setup icinga-web with pnp4nagios

As introducing how to install Icinga and Icinga-web before, I am trying to install pnp4nagios and setup icinga-web with pnp4nagios. As Nagios and Icinga themselves have no graphing function, some may use Cacti or Munin for graphing performance data. There's an addon called PNP4nagios released in Nagios Addon Project, which analyzes performance data provided by nagios-plugins and stores them automatically into RRD-databases.

Reference
Setting up PNP with Icinga
Integration of PNP4nagios into Icinga-web

Then, let's see how to install pnp4nagios and integrate it into Icinga-web.

install pnp4nagios

install rrdtool, perl-rrdtool

# rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
# rpm -ivh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm
# sed -i 's|enabled\s\?=\s\?1|enabled = 0|' /etc/yum.repos.d/rpmforge.repo
# yum -y install pango.x86_64 pango-devel.x86_64 glib2.x86_64 glib2-devel.x86_64
# yum -y --enablerepo=rpmforge install rrdtool perl-rrdtool

install pnp4nagios

$ curl http://downloads.sourceforge.net/project/pnp4nagios/PNP-0.6/pnp4nagios-0.6.16.tar.gz | tar zx
$ cd pnp4nagios-0.6.16
./configure  \
--prefix=/usr/local/pnp4nagios-0.6.16  \
--with-nagios-user=icinga \

$ make all
# make install install-webconf install-config install-init
# ln -s /usr/local/pnp4nagios-0.6.16 /usr/local/pnp4nagios

Before setting up the configuration, I'll explain the art of collecting data of pnp4nagios. Pnp4nagios has 5 kinds of ways to collect data, synchronous-mode, bulk mode, bulk mode with NPCD, bulk mode with npcdmod, and gearman mode. The detail about each way is shown, here. I adopt bulk mode with npcdmod, but I am also showing how to setup bulk mode with NPCD.
