　　rrdtool安装
　　pnp是基于php和perl,所有这两个软件包必须先安装好。rrdtool是用来采集nagios数据并生成绘图
　　[root@localhost tmp]# tar -zxvf rrdtool-11.0.50.tar.gz
　　[root@localhost tmp]# cd rrdtool-1.0.50/
　　[root@localhost rrdtool-1.0.50]# ./configure
　　[root@localhost rrdtool-1.0.50]# make
　　[root@localhost rrdtool-1.0.50]# make install
　　pnp安装
　　[root@localhost tmp]# tar -zxvf pnp-0.4.14.tar.gz
　　[root@localhost tmp]# cd pnp-0.4.14
　　[root@localhost pnp-0.4.14]# ./configure –with-rrdtool=/usr/local/rrdtool-1.0.50/bin/rrdtool
　　configure: error: Perl Module Time::HiRes not available
　　[root@localhost pnp-0.4.14]# yum install perl-Time-HiRes
　　[root@localhost pnp-0.4.14]# ./configure –with-rrdtool=/usr/local/rrdtool-1.0.50/bin/rrdtool
　　*** Configuration summary for pnp 0.4.14 05-02-2009 ***
　　General Options:
　　————————- ——————-
　　Nagios user/group: nagios nagios
　　Install directory: /usr/local/nagios
　　HTML Dir: /usr/local/nagios/share/pnp
　　Config Dir: /usr/local/nagios/etc/pnp
　　Location of rrdtool binary: /usr/local/rrdtool-1.0.50/bin/rrdtool Version 1.0.50
　　RRDs Perl Modules: *** NOT FOUND ***
　　RRD Files stored in: /usr/local/nagios/share/perfdata
　　process_perfdata.pl Logfile: /usr/local/nagios/var/perfdata.log
　　Perfdata files (NPCD) stored in: /usr/local/nagios/var/spool/perfdata/
　　Review the options above for accuracy. If they look okay,
　　type ‘make all’ to compile.
　　WARNING: The RRDs Perl Modules are not found on your System
　　Using RRDs will speedup things in larger Installtions.
　　[root@localhost pnp-0.4.14]# make all
　　[root@localhost pnp-0.4.14]# make install
　　[root@localhost pnp-0.4.14]# make install-config
　　[root@localhost pnp-0.4.14]# make install-init
　　编辑httpd.conf，在DirectoryIndex后面加上index.php
　　DirectoryIndex index.html index.php
　　[root@localhost pnp-0.4.14]#service httpd restart
　　在浏览器中访问http://192.168.1.66/nagios/pnp/index.php?host=localhost

　　Nagios增加绘图
　　[root@localhost /]# vi /usr/local/nagios/etc/nagios.cfg
　　#将0改为1
　　process_performance_data=1
　　#去掉一下2行注释
　　host_perfdata_command=process-host-perfdata
　　service_perfdata_command=process-service-perfdata
　　将commands.cfg最后面的command_line后的内容替换为下面的内容
　　[root@localhost /]# vi /usr/local/nagios/etc/objects/commands.cfg
　　# ‘process-host-perfdata’ command definition
　　define command{
　　command_name process-host-perfdata
　　command_line /usr/local/nagios/libexec/process_perfdata.pl
　　}
　　# ‘process-service-perfdata’ command definition
　　define command{
　　command_name process-service-perfdata command_line /usr/local/nagios/libexec/process_perfdata.pl
　　}
　　修改localhost.cfg 文件，在define service加入以下参数（颜色标注）
　　[root@localhost /]# vi /usr/local/nagios/etc/objects/localhost.cfg
　　define service{
　　use local-service ; Name of service template to use
　　host_name localhost
　　service_description PING
　　check_command check_ping!100.0,20%!500.0,60%

　　action_url /nagios/pnp/index.php?host=$HOSTNAME$
　　}
　　define service{
　　use local-service ; Name of service template to use
　　host_name localhost
　　service_description Root Partition
　　check_command check_local_disk!20%!10%!/
　　process_perf_data 1
　　action_url /nagios/pnp/index.php?host=$HOSTNAME$
　　}
　　define service{
　　use local-service ; Name of service template to use
　　host_name localhost
　　service_description Current Users
　　check_command check_local_users!20!50
　　process_perf_data 1
　　action_url /nagios/pnp/index.php?host=$HOSTNAME$
　　}
　　define service{
　　use local-service ; Name of service template to use
　　host_name localhost
　　service_description Total Processes
　　check_command check_local_procs!250!400!RSZDT
　　process_perf_data 1
　　action_url /nagios/pnp/index.php?host=$HOSTNAME$
　　}
　　define service{
　　use local-service ; Name of service template to use
　　host_name localhost
　　service_description Current Load
　　check_command check_local_load!5.0,4.0,3.0!10.0,6.0,4.0
　　process_perf_data 1
　　action_url /nagios/pnp/index.php?host=$HOSTNAME$
　　}
　　define service{
　　use local-service ; Name of service template to use
　　host_name localhost
　　service_description Swap Usage
　　check_command check_local_swap!20!10
　　process_perf_data 1
　　action_url /nagios/pnp/index.php?host=$HOSTNAME$
　　}
　　define service{
　　use local-service ; Name of service template to use
　　host_name localhost
　　service_description SSH
　　check_command check_ssh
　　notifications_enabled 0
　　process_perf_data 1
　　action_url /nagios/pnp/index.php?host=$HOSTNAME$
　　}
　　define service{
　　use local-service ; Name of service template to use
　　host_name localhost
　　service_description HTTP
　　check_command check_http
　　notifications_enabled 0
　　process_perf_data 1
　　action_url /nagios/pnp/index.php?host=$HOSTNAME$
　　}
　　[root@localhost /]# service httpd restart
　　[root@localhost /]# service nagios restart
　　Running configuration check…done.
　　Stopping nagios: done.
　　Starting nagios:This account is currently not available.
　　done.
　　重启httpd和nagios后重新打开web监控页面，此时服务状态多出一列小太阳图标，点击该图标可直接调出绘图页面，效果如图：
