# tar zxvf rrdtool-1.4.5.tar.gz && cd rrdtool-1.4.5 && ./configure --prefix=/usr/local/rrdtool && make && make install 2、安装pnp tar zxvf pnp-0.4.13.tar.gz && cd pnp-0.4.13 && ./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-config && make install-init 安装完成，PNP默认文件放置情况如下： 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 Path to rrdtool: /usr/local/bin/rrdtool (Version 1.4.5) 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/ ps:RRDs Perl Modules: *** NOT FOUND *** 在这里我遇到一个很奇怪的问题，由于没有安装rrds perl模块，导致pnp出图的数据是乱码，附上图片：  后来通过yum install rrdtool-perl就恢复正常了，有图有真相
3、配置PNP，创建默认配置文件 # cd /usr/local/nagios/etc/pnp/ # cp process_perfdata.cfg-sample process_perfdata.cfg # cp npcd.cfg-sample npcd.cfg # cp rra.cfg-sample rra.cfg # chown -R nagios:nagios /usr/local/nagios/etc/pnp 修改process_perfdata.cfg文件 vim /usr/local/nagios/etc/pnp/process_perfdata.cfg LOG_FILE = /usr/local/nagios/var/perfdata.log # # Loglevel 0=silent 1=normal 2=debug # LOG_LEVEL = 2 这里将日志级别改为2，即debug模式。 4、修改Nagios配置文件 1、增加小太阳图标 修改templates.cfg，增加一个定义PNP的host和service。修改后的内容如下： define host { name host-pnp register 0 #action_url /nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_' class='tips' rel='/nagios/index.php/popup?host=$HOSTNAME$&srv=_HOST_ action_url /nagios/pnp/index.php?host=$HOSTNAME$ process_perf_data 1 } ps：我这里只添加了主机的小太阳图标，每当添加某主机的服务的时候，都会自动生成该服务的数据文件
define command{ command_name process-host-perfdata command_line /usr/local/nagios/libexec/process_perfdata.pl } 3、让主机引用host-perfdata # cat hosts.cfg define host{ use host-pnp host_name xx alias xx(x) address xx contact_groups shyygroup check_command check-host-alive max_check_attempts 5 notification_interval 10 notification_period 24x7 notification_options d,u,r } 4、重启nagios服务后，在这个目录下会产生2个主机的目录 ls /usr/local/nagios/share/perfdata/ xxjshyy xxysix cd xxjshyy -rw-rw-r-- 1 nagios nagioscmd 1151496 Dec 21 16:13 Current_Load.rrd -rw-rw-r-- 1 nagios nagioscmd 12165 Dec 21 16:13 Current_Load.xml -rw-rw-r-- 1 nagios nagioscmd 384952 Dec 21 16:11 Java_9800.rrd -rw-rw-r-- 1 nagios nagioscmd 11208 Dec 21 16:11 Java_9800.xml -rw-rw-r-- 1 nagios nagioscmd 384952 Dec 21 16:12 Java_9801.rrd -rw-rw-r-- 1 nagios nagioscmd 11208 Dec 21 16:12 Java_9801.xml -rw-rw-r-- 1 nagios nagioscmd 384952 Dec 18 17:35 mysql_3306.rrd -rw-rw-r-- 1 nagios nagioscmd 384952 Dec 21 16:11 Mysql_3306.rrd -rw-rw-r-- 1 nagios nagioscmd 11199 Dec 18 17:35 mysql_3306.xml -rw-rw-r-- 1 nagios nagioscmd 11202 Dec 21 16:11 Mysql_3306.xml -rw-rw-r-- 1 nagios nagioscmd 384952 Dec 21 16:12 Nrpe_5666.rrd -rw-rw-r-- 1 nagios nagioscmd 11198 Dec 21 16:12 Nrpe_5666.xml -rw-rw-r-- 1 nagios nagioscmd 768224 Dec 21 16:14 Ping.rrd -rw-rw-r-- 1 nagios nagioscmd 11702 Dec 21 16:14 Ping.xml -rw-rw-r-- 1 nagios nagioscmd 384952 Dec 21 16:14 sda3.rrd -rw-rw-r-- 1 nagios nagioscmd 11170 Dec 21 16:14 sda3.xml -rw-rw-r-- 1 nagios nagioscmd 1534768 Dec 21 16:13 traffic.rrd -rw-rw-r-- 1 nagios nagioscmd 12701 Dec 21 16:13 traffic.xml -rw-rw-r-- 1 nagios nagioscmd 384952 Dec 21 16:12 Users.rrd -rw-rw-r-- 1 nagios nagioscmd 11120 Dec 21 16:12 Users.xml ps:点击小太阳也能会报以下这种错误： Deprecated: Assigning the return value of new by reference is deprecated in /usr/local/nagios/share/pnp/include/function.inc.php on line 1026 Warning: date() [function.date]: It is not safe to rely on the system's timezone settings.
