Icinga with PNP4Nagios


PNP4Nagios

PNP는 여러 Plugin으로 부터 얻어온 성능 데이터를 분석하여 RRD 데이터베이스 (Round Robin Databases, see RRD Tool)에 자동 저장해주는 Nagios add-on 프로그램이다.
이 페이지에서 PNP4Nagios는 Bulk mode with NPCD 모드로 설정하도록 한다. 자세한 모드 설명은 링크를 참조한다.

Prerequisites

yum install rrdtool-perl rrdtool rrdtool-devel -y
yum install perl-Time-HiRes -y

Build

tar zxvf pnp4nagios-0.6.21 -C /tmp
cd /tmp/pnp4nagios-0.6.21
./configure --with-nagios-user=icinga --with-nagios-group=icinga
make all
make install
make install-webconf
make install-config

Enable BULK Mode with NPCD

make install-init
Start Apache Web Server
service httpd restart
Configuration - Bulk Mode with NPCD
Edit Configuration
/usr/local/pnp4nagios/etc/config.php
$conf['nagios_base'] = "/icinga/cgi-bin";

Start Daemon

chkconfig npcd on
service npcd start
service icinga reload

Integration into Classic-UI

Copy SSI Header File

cp /tmp/pnp4nagios-0.6.18/contrib/ssi/status-header.ssi /usr/local/icinga/share/ssi/status-header.ssi
chown icinga: /usr/local/icinga/share/ssi/status-header.ssi

Default Popups

action_url templates
  • 기존 Template 선언에 action_url을 추가
define host {
  use   linux-server
        name       pnp-host
        register    0
        action_url  /pnp4nagios/graph?host=$HOSTNAME$' class='tips' rel='/pnp4nagios/popup?host=$HOSTNAME$&srv=_HOST_
}

define service {
  use   generic-service
        name        pnp-service
        register    0
        action_url  /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$' class='tips' rel='/pnp4nagios/popup?host=$HOSTNAME$&srv=$SERVICEDESC$
}
  • 실제로 사용하기 위해서는 pnp-host, pnp-service 템플릿에 다른 템플릿 처럼 여러 설정을 해주어야 Host나 Service Define항목에서 사용하기 좋을 것이다. 위와 같이 use를 사용하여 확장하는 것도 좋은 방법이 될 수 있다.
  • use pnp-host와 pnp-service를 사용하여 PNP4Nagios 사용을 명시
define host{
        name                            generic-host
        use                             pnp-host
...

define service{
        name                            generic-service
        use                             pnp-service

  </cronk>
 </cronks>
    </ae:configuration>
</ae:configurations>

Making the grid view just created as default (Optional)

mv data/xml/grid/icinga-host-template.xml data/xml/grid/icinga-host-template.bak
mv data/xml/grid/icinga-my-host-template.xml data/xml/grid/icinga-host-template.xml
mv data/xml/grid/icinga-service-template.xml data/xml/grid/icinga-service-template.bak
mv data/xml/grid/icinga-my-service-template.xml data/xml/grid/icinga-service-template.xml
이 경우는 /usr/local/icinga-web/app/modules/Cronks/config/cronks.xml에 cronk를 추가할 필요가 없음!

Clear cache

/usr/local/icinga-web/bin/clearcache.sh
or
rm -f /usr/local/icinga-web/app/cache/config/*.php

Check new grid view
