cd /etc/nagios
vim nagios.cfg
process_performance_data=1
#将此变量值设为1
host_perfdata_command=process-host-perfdata
service_perfdata_command=process-service-perfdata
#取消这两项的注释

cd /etc/nagios/objects
vim commands.cfg
# 'process-host-perfdata' command definition
define command{
command_name process-host-perfdata
command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl
}
# 'process-service-perfdata' command definition
define command{
command_name process-service-perfdata
command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl
}
#添加上面两行在文件的末行 ，并删除或注释掉原有对process-host-perfdata和process-service-perfdata进行定义的字段
12.添加小太阳模版，镶嵌在nagios页面上。
cd /etc/nagios/objects

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
}
#回到解压目录下，复制鼠标悬停图标显示，预览绘图所需的文件到nagios html目录
