Installation

The installation of PNP will be described in more detail. It is expected that nagios was compiled from source and is located in /usr/local/nagios.
Attention: The description applies to the developer version PNP 0.6.0.
Please note that PNP has to be configured after the installation.

Make and more

The installation of PNP is controlled by makefiles. The system is analyzed after invocation of ./configure and the detected values are tranferred to makefiles.

Please unpack PNP as user root:

tar -xvzf pnp4nagios-HEAD.tar.gz
cd pnp4nagios

./configure is to be called from the directory pnp4nagios.

./configure

Note: Without specifying any options user and group will be “nagios”. If you have different values then please use the parameters ”--with-nagios-user” and ”--with-nagios-group”, respectively. Using Icinga the call might be

./configure --with-nagios-user=icinga --with-nagios-group=icinga

Some lines run across the screen. The output at the end is important.

*** Configuration summary for pnp4nagios-0.6.2 23-12-2009 ***

  General Options:
  -------------------------         -------------------
  Nagios user/group:                nagios nagios
  Install directory:                /usr/local/pnp4nagios
  HTML Dir:                         /usr/local/pnp4nagios/share
  Config Dir:                       /usr/local/pnp4nagios/etc
  Location of rrdtool binary:       /usr/bin/rrdtool Version 1.2.12
  RRDs Perl Modules:                FOUND (Version 1.2012)
  RRD Files stored in:              /usr/local/pnp4nagios/var/perfdata
  process_perfdata.pl Logfile:      /usr/local/pnp4nagios/var/perfdata.log
  Perfdata files (NPCD) stored in:  /usr/local/pnp4nagios/var/spool

  Web Interface Options:  -------------------------         -------------------
  HTML URL:                         http://localhost/pnp4nagios/
  Apache Config File:               /etc/apache2/conf.d/pnp4nagios.conf


  Review the options above for accuracy.  If they look okay,
  type 'make all' to compile.

The paths shown should be checked. If the displayed values aren't correct you can change them calling ./configure with appropriate options.
Attention: “Location of rrdtool binary” means path including name of binary! If necessary it can be specified using the following syntax:

 ./configure --with-rrdtool=/usr/local/rrdtool-1.2.xx/bin/rrdtool
 ./configure --help 

shows the supported options.

Invoking

 make all

compiles the components like NPCD which are written in C

 make install

copies everything to the right places in the file system. The paths were already shows during ./configure.

After the installation of the program and HTML files you can copy a sample Apache configuration file to your web-server config directory

 make install-webconf

You can call

 make install-config

optionally. This way config files for process_perfdata.pl and npcd are copied to etc/pnp.

To install the NPCD Init script call

 make install-init

All these steps are combined in

 make fullinstall

Note: As already stated the Nagios settings will be used per default. If you are using Icinga the file '/etc/apache2/conf.d/pnp4nagios.conf' has to be edited to change the path to AuthUserFile (the path may differ between distributions):

#       AuthUserFile /usr/local/nagios/etc/htpasswd.users
        AuthUserFile /usr/local/icinga/etc/htpasswd.users

Attention: After copying the configuration file for the web server you have to restart the web server (service httpd restart or /etc/init.d/apache2 restart, respectively).

Update

The update of a 0.6.x version works (nearly) the same way as an installation. Please note that you have to call ./configure with the same options you used during the first installation. Please check if you changed anything in the folder share/templates.dist. Own templates should be placed in share/templates to avoid being overwritten.
Attention: If you changed config.php then you should save this file before it is overwritten when you execute make install-config.

You can skip make install-webconf and make install-init because nothing changed between 0.6.x versions.

The components

After installation the components of PNP were copied to the appropriate places in the file system. These are

the PHP-Files for the web-frontend below

 /usr/local/pnp4nagios/share

the data collector process_perfdata.pl in

 /usr/local/pnp4nagios/libexec

sample config files with the suffix -sample in

 /usr/local/pnpnagios/etc

the config file config.php for the web frontend in

 /usr/local/pnp4nagios/etc
