6.配置nagios 和pnp4nagios
6.1. vim /etc/nagios/nagios.cfg
process_performance_data=0 //0改成1
host_perfdata_command=process-host-perfdata //去掉注释
service_perfdata_command=process-service-perfdata //去掉注释
6.2. vim /etc/nagios/objects/commands.cfg
define command{
command_name process-host-perfdata
command_line /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl -d HOSTPERFDATA
}

define command{
command_name process-service-perfdata
command_line /user/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl
}
6.3. vim /etc/nagios/objects/templates.cfg
define host{
name host-pnp
action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_
register 0
process_perf_data 1
}

define service{
name service-pnp
action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
register 0
process_perf_data 1
}
6.4. cd /etc/nagios/objects/ //默认localhost.cfg文件包含本机及本机服务的配置
vim hosts.cfg //新建主机配置文件hosts.cfg
define host{
use linux-server,host-pnp
host_name localhost
alias localhost

}
define hostgroup{
hostgroup_name linux-servers

host_name localhost
service_description PING
check_command check_ping!100.0,20%!500.0,60%
}
6.5. vim /etc/nagios/nagios.cfg //新增以下2条

cfg_file=/etc/nagios/objects/hosts.cfg
