nagios安装完了，只有数字输出监控内容是不是不炫丽呢?是不是想像CACTI 一样出炫丽的图呢？那你可以选择PNP，他可以满足你的需求，只要你的脚本符合perfdata规则，那么rrdtool就可以出数据，PNP就可以用图给你画出来。

安装pnp4nagios

# yum -y install pnp4nagios

重载apache

# service httpd reload

配置nagios

# vim /etc/nagios/nagios.cfg

修改以下参数

process_performance_data=1 将0改为1，并在下面添加如下内容

# *** the template definition differs from the one in the original nagios.cfg
#
service_perfdata_file=/var/log/pnp4nagios/service-perfdata
service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=15
service_perfdata_file_processing_command=process-service-perfdata-file

# *** the template definition differs from the one in the original nagios.cfg
#
host_perfdata_file=/var/log/pnp4nagios/host-perfdata
host_perfdata_file_template=DATATYPE::HOSTPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tHOSTPERFDATA::$HOSTPERFDATA$\tHOSTCHECKCOMMAND::$HOSTCHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$
host_perfdata_file_mode=a
host_perfdata_file_processing_interval=15
host_perfdata_file_processing_command=process-host-perfdata-file

修改commands.cfg

# vim /etc/nagios/objects/commands.cfg

注释掉原有对process-host-perfdata和process-service-perfdata，重新定义

#
# Bulk with NPCD mode
#
define command {
command_name process-service-perfdata-file
command_line /bin/mv /var/log/pnp4nagios/service-perfdata /var/spool/pnp4nagios/service-perfdata.$TIMET$
}

define command {
command_name process-host-perfdata-file
command_line /bin/mv /var/log/pnp4nagios/host-perfdata /var/spool/pnp4nagios/host-perfdata.$TIMET$
}

修改templates.cfg

# vim /etc/nagios/objects/templates.cfg

添加如下内容

define host {
name host-pnp
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_
register 0
}

define service {
name srv-pnp
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
register 0
}

如果将pnp4nagios集成到nagios web中，而不需要点击任何图标，请添加如下内容：

#Popups
define host {
name host-pnp
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_' class='tips' rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=_HOST_
register 0
}

define service {
name srv-pnp
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$' class='tips' rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=$SERVICEDESC$
register 0
}

并复制status-header.ssi到nagios网站目录下

# cp /usr/share/doc/pnp4nagios-0.6.22/contrib/ssi/status-header.ssi /usr/share/nagios/html/ssi/

修改linux-server，添加host-pnp

define host{
name linux-server ; The name of this host template
use generic-host,host-pnp

修改windows-server，添加host-pnp

define host{
name windows-server ; The name of this host template
use generic-host,host-pnp

修改service，添加srv-pnp

define service{
name local-service ; The name of this service template
use generic-service,srv-pnp

启动npcd

# service npcd start

将npcd加到开机启动

# chkconfig npcd on

重新加载nagios配置

# service nagios reload

pnp4nagios模板位置

自定义模板位置：/usr/share/nagios/html/pnp4nagios/templates

pnp包自带的模板位置：/usr/share/nagios/html/pnp4nagios/templates.dist
