# mv check_all_local_disks.cfg-samplecheck_all_local_disks.cfg
# mv check_nrpe.cfg-samplecheck_nrpe.cfg
# mv check_nwstat.cfg-samplecheck_nwstat.cfg
启动npcd服务
# service npcd start
# vi /usr/local/nagios/etc/nagios.cfg(把前面的注释符"#"去掉)
process_performance_data=1 (原为process_performance_data=0)
host_perfdata_command=process-host-perfdata
service_perfdata_command=process-service-perfdata
:wq
# vi /usr/local/nagios/etc/objects/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
}
:wq
注：要注释掉原有对process-service-perfdata和process-host-perfdata的定义
为主机添加小太阳图标
# vi /usr/local/nagios/etc/objects/yang.cfg
define host {
use linux-server
host_name yang
address 192.168.1.10
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$
}
:wq
为单个服务添加小太阳图标
# vi /usr/local/nagios/etc/objects/yang.cfg
define service {
use generic-service
host_name yang
service_description check_load
check_command check_nrpe!check_load
normal_check_interval 2
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
}
:wq
重启 nagios 服务
# service nagios restart
# mv /usr/local/pnp4nagios/share/install.php/usr/local/pnp4nagios/share/install2.php (或者直接删除)
注：点击小太阳图标后会出现个测试页面，各项要求都PASS了，会提示你重命名或删除install.php文件，原因不详
# ls /usr/local/pnp4nagios/var/perfdata(看下面有没有nagios中定义的主机名目录以及目录下面有没有对应服务的rrd文件和xml文件)
注：nagio图像（pnp4nagios）只能显示nagios插件中的服务，以脚本监控的服务不显示图像
