最近搞了搞nagios並對最新版本的pnp加了圖形，現就配置過程，寫成文檔如下，以備忘，也給廣大同行一個借鑑參考。
一、下載安裝
tar -xzvf pnp4nagios-0.6.16.tar.gz
cd pnp4nagios-0.6.16
./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-rrdtool=/usr/local/rrdtool/bin/rrdtool --with-perfdata-dir=/usr/local/nagios/share/perfdata
make all
make install
make install-webconf（可不做，只是安裝pnp4nagios.conf文件到此路徑： /etc/httpd/conf.d/pnp4nagios.conf下，可自行添加到httpd.conf中）
make install-config
make install-init
二、配置
1、配置nagios.cfg添加以下參數
process_performance_data=1
host_perfdata_command=process-host-perfdata
service_perfdata_command=process-service-perfdata
enable_environment_macros=1
之後找到836行, 註釋此語句
#process_performance_data=0
2、將下列配置文件重命名，使之能夠被程序識別
cd /usr/local/pnp4nagios/etc
mv nagios.cfg-sample nagios.cfg （可不做）
mv misccommands.cfg-sample misccommands.cfg
mv rra.cfg-sample rra.cfg
cd /usr/local/pnp/etc/pages/
mv web_traffic.cfg-sample web_traffic.cfg
cd ../check_commands/
mv check_all_local_disks.cfg-sample check_all_local_disks.cfg
mv check_nrpe.cfg-sample check_nrpe.cfg
service npcd restart
3、修改nagios下配置文件 commands.cfg
添加下面兩行在文件的末行 ，並刪除或註釋掉原有對process-host-perfdata和process-service-perfdata進行定義的字段
define command {
command_name process-service-perfdata
command_line /usr/bin/perl /usr/local/pnp4nagios/libexec/process_perfdata.pl
}
define command {
command_name process-host-perfdata
command_line /usr/bin/perl /usr/local/pnp4nagios/libexec/process_perfdata.pl -d HOSTPERFDATA
}
4、修改配置文件templates.cfg
define host {
name hosts-pnp
register 0
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_' class='tips' rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=_HOST_
process_perf_data 1
}
define service {
name srv-pnp
register 0
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$' class='tips' rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=$SERVICEDESC$
process_perf_data 1
}
5、回到pnp解壓目錄下，複製鼠標懸停圖標顯示，預覽繪圖所需的文件 .
cd /root/soft/pnp4nagios-0.6.16/contrib/ssi
cp * /usr/local/nagios/share/ssi/
懸停在小太陽上就會出現預覽圖
6、定義監控服務和主機配置文件
修改主機配置文件
define host{
use standard-server,hosts-pnp
host_name localhost-93
alias 192.168.1.93
address 192.168.1.93
}
define host{
use standard-server,hosts-pnp
host_name 192.168.1.46
alias 192.168.1.46
address 192.168.1.46
}
修改服務配置文件
define service {
use service-all,srv-pnp
host_name localhost-93
service_description check-http
check_command check_http
}
define service {
use service-all,srv-pnp
host_name localhost-93
service_description check-disk
check_command check_nrpe!check_disk
}
define service {
use service-all,srv-pnp
host_name localhost-93
service_description check-alive
check_command check-host-alive
}
define service {
use service-all,srv-pnp
host_name localhost-93
service_description check-load
check_command check_nrpe!check_load
}
define service {
use service-all,srv-pnp
host_name localhost-93
service_description Prot-3306
check_command check_tcp!3306!-t 30 -w 10 -c 20
｝
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
重啓nagios: service nagios restart
7、修改apache配置文件添加下列
Alias /pnp4nagios "/usr/local/pnp4nagios/share" (也不能隨便改路徑否則無法點擊小 太陽無法找到pnp4nagios訪問，如果要改需要修改PHP文件)
<Directory "/usr/local/pnp4nagios/share">
AllowOverride None
Order allow,deny
Allow from all
#
# Use the same value as defined in nagios.conf
#
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
<IfModule mod_rewrite.c>
# Turn on URL rewriting
RewriteEngine On
Options FollowSymLinks
# Installation directory
RewriteBase /pnp4nagios/
# Protect application and system files from being viewed
RewriteRule ^(application|modules|system) - [F,L]
# Allow any files or directories that exist to be displayed directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Rewrite all other URLs to index.php/URL
RewriteRule .* index.php/$0 [PT,L]
</IfModule>
</Directory>
重啓apache: /usr/local/apache/bin/httpd -k restart
三、測試
chmod +x verify_pnp_config
perl verify_pnp_config --mode sync --config=/usr/local/nagios/etc/nagios.cfg --pnpcfg=/usr/local/pnp4nagios/etc

1、pnp 編譯錯誤
configure: error: Perl Module Time::HiRes not available
解決：
yum instal perl*
2、編譯時候出現
RRDs Perl Modules: *** NOT FOUND ***
解決：
cp /usr/local/rrdtool/lib/perl/5.8.5/i386-linux-thread-multi/auto/RRDs /RRDs.so /usr/lib/perl5/5.8.5/i386-linux-thread-multi/
cp /usr/local/rrdtool/lib/perl/5.8.5/i386-linux-thread-multi/* /usr/lib/perl5/5.8.5/i386-linux-thread-multi/
3、php5.1.6無GD模塊
快速添加
yum install php-gd
重啓apache
四、生成的圖像
