nagios图形监控和管理
1、Pnp安装图形监控曲线（服务器端）
Pnp出图软件官方站点：http://docs.pnp4nagios.org/
2、执行yum安装基础pnp软件需要依赖的包：
yum install cairo pango zlib zlib-devel freetype freetype-devel gd dg-devel -y
3、安装libart_lgpl
tar xf libart_lgpl-2.3.17.tar.gz
cd libart_lgpl-2.3.17
./configure
make
make install
/bin/cp -r /usr/local/include/libart-2.0 /usr/include/
cd ../
# 原理：利用rrdtool （轮询数据库工具）出图
4、安装rrdtool
tar xf rrdtool-1.2.14.tar.gz
cd rrdtool-1.2.14
./configure --prefix=/usr/local/rrdtool --disable-python --disable-ct1
##WARNING: The RRDs Perl Modules are not found on your System
#Using RRDs will speedup things in larger Installtions.
#configure后出现上面的提示可以不用理会。
make
make install
cd ..
#关注：ls /usr/local/rrdtool/bin/
rrdcgi rrdtool rrdupdate 表示成功
5、安装负责图形展示的pnp-0.4.14.tar.gz
tar zxf pnp-0.4.14.tar.gz
cd pnp-0.4.14
./configure \
--with-rrdtool=/usr/local/rrdtool/bin/rrdtool --with-perfdata-dir=/usr/local/nagios/share/perfdata/
问题：configure报错（一般不会发生）
checking for linker flags for loadable modules... -shared
checking for Perl Module Time::HiRes... no
configure: error: Perl Module Time::HiRes not available
解决：yum install perl-Time-HiRes -y

#####################
make all
make install
make install-config
make install-init
ll /usr/local/nagios/libexec/ |grep process #（用来搜集数据）
6、出图的配置
vi nagios.cfg +833
833 process_performance_data=1
#1记录数据，0不记录数据
837 # HOST AND SERVICE PERFORMANCE DATA PROCESSING COMMANDS
838 # These commands are run after every host and service check is
839 # performed. These commands are executed only if the
840 # enable_performance_data option (above) is set to 1. The command
841 # argument is the short name of a command definition that you
842 # define in your host configuration file. Read the HTML docs for
843 # more information on performance data.
844
845 host_perfdata_command=process-host-perfdata
#主机记录数据
846 service_perfdata_command=process-service-perfdata
#服务记录数据
执行编辑命令 vi /usr/local/nagios/etc/objects/commands.cfg +227，修改commands.cfg配置文件。
#修改commands.cfg 配置文件，约227-238行
#默认配置为（如果没有直接添加即可）
#-----------------------------------------------------------------
# 'process-host-perfdata' command definition
define command{
command_name process-host-perfdata
command_line /usr/bin/printf "%b" "$LASTHOSTCHECK$\t$HOSTNAME$\t$HOSTSTATE$\t$HOSTATTEMPT$\t$HOSTSTATETYPE$\t$HOSTEXECUTIONTIME$\t$HOSTOUTPUT$\t$HOSTPERFDAT A$\n" >> /usr/local/nagios/var/host-perfdata.out
}
# 'process-service-perfdata' command definition
define command{
command_name process-service-perfdata
command_line /usr/bin/printf "%b" "$LASTSERVICECHECK$\t$HOSTNAME$\t$SERVICEDESC$\t$SERVICESTATE$\t$SERVICEATTEMPT$\t$SERVICESTATETYPE$\t$SERVICEEXECUTIONTIME$\t$SERVICELATENCY$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$\n" >> /usr/local/nagios/var/service-perfdata.out
}
修改成如下配置
# '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
}
也可以用nagios变量$USER1$替代/usr/local/nagios/libexec/路径
执行检查语法命令/etc/init.d/nagios checkconfig
Total Warnings: 0
Total Errors: 0
根据提示，配置通过。重启。
7、 vi templates.cfg
58 process_perf_data 1 ; Process performance data
#出图控制，可以在服务、主机、模版添加；
8、绑定主机出图整合nagios
define host{
use linux-server
host_name nagios
alias nagios-01
address 10.0.0.23
action_url /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
}
#可以在 模版vi templates.cfg 里linux-server里添加
/nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
#重启服务后观察主机的监控，如图，点人即可： 
9、绑定服务出图整合nagios
vi services.cfg
define service{
use generic-service
host_name nagios,C
service_description Disk Partition
check_command check_nrpe!check_disk
action_url /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
}
10、出图的数据路径：/usr/local/nagios/share/perfdata/
出图地址：http://10.0.0.22/nagios/pnp/index.php
