PNP4NAGIOS怎么安装自己网上找吧，懒得整理了

首先编辑/usr/local/nagios/etc/nagios.cfg文件，在文件中添加

process_performance_data=1

#
# service performance data
#
service_perfdata_file=/usr/local/pnp4nagios/var/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

#
# host performance data starting with Nagios 3.0
# 
host_perfdata_file=/usr/local/pnp4nagios/var/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

其次编辑/usr/local/nagios/etc/objects/commands.cfg,添加以下配置

define command{
       command_name    process-service-perfdata-file
       command_line    /bin/mv /usr/local/pnp4nagios/var/service-perfdata /usr/local/pnp4nagios/var/spool/service-perfdata.$TIMET$
}

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

Using these commands the file service-perfdata will be moved to var/spool/ after the interval specified in service_perfdata_file_processing_interval has passed. The Nagios macro $TIMET$ is appended to the filename to avoid overwriting of old files unintentionally. The macro $TIMET$ contains the current timestamp in time_t format (seconds since the UNIX epoch).

In the directory /usr/local/pnp4nagios/var/spool/ files are gathered to be processed by NPCD.

NPCD monitors the spool directory and passes the file names to process_perfdata.pl. This way processing of performance data is completely decoupled from nagios.

Before starting NPCD you have to check the paths to the spool directory and toprocess_perfdata.pl specified in the config file npcd.cfg. The only thing that remains is to start NPCD.

 /usr/local/pnp4nagios/bin/npcd -d -f /usr/local/pnp4nagios/etc/npcd.cfg

第三,在/usr/local/nagios/etc/objects/templates.cfg中添加定义host和service模板：

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
        }

最后,在需要查看图像化的host和service定义中添加第三步定义的模板

在hosts.cfg中添加use host-pnp,generic-host

service.cfg 添加 use srv-pnp,generic-service

vi hosts.cfg

define host{
        use                             generic-host,host-pnp
        host_name                       gc1
        alias                           gc1
        address                         192.168.10.150
        check_command                   check-host-alive
        max_check_attempts              5
        check_period                    24x7
        contact_groups                  admins
        notification_interval           10
        notification_period             24x7
        notification_options            d,u,r
        }

define host{
        use                             generic-host,host-pnp
        host_name                       gc2
        alias                           gc2
        address                         192.168.10.152
        check_command                   check-host-alive
        max_check_attempts              5
        check_period                    24x7
        contact_groups                  admins
        notification_interval           10
        notification_period             24x7
        notification_options            d,u,r
        }

vi services.cfg

define service{

use generic-service,srv-pnp

host_name gc2

service_description check-host-alive

check_command check-host-alive

max_check_attempts 5

normal_check_interval 3

retry_check_interval 2

check_period 24x7

notification_interval 10

notification_period 24x7
