Nagios-PNP绘图
本文转自：http://www.yylog.org/?p=4287rrdtool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
# tar -zxvf rrdtool-11.0.50.tar.gz
# cd rrdtool-1.0.50/
# ./configure
# make
# make install
pnp安装
# tar -zxvf pnp-0.4.14.tar.gz
# cd pnp-0.4.14
# ./configure –with-rrdtool=/usr/local/rrdtool-1.0.50/bin/rrdtool
configure: error: Perl Module Time::HiRes not available
# yum install perl-Time-HiRes
# ./configure –with-rrdtool=/usr/local/rrdtool-1.0.50/bin/rrdtool

编辑httpd.conf，在DirectoryIndex后面加上index.php
DirectoryIndex index.html index.php
#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
# 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
# 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）
# vi /usr/local/nagios/etc/objects/localhost.cfg
define service{
use local-service ; Name of service template to use
host_name localhost

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：
