Nagios结合pnp4nagios图形监控

#下面是Bulk Mode with NPCD模式配置

cd /usr/local/nagios/etc/objects/

vim commands.cfg
# 'process-host-perfdata' command definition
#注释默认的process-host-perfdata和process-service-perfdata，添加以下
define command{
 command_name process-service-perfdata-file

配置完成，检查nagios配置后将nagios和apache重启

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

出现这个页面说明安装完成，那么将install.php删除后刷新即可看到出图的页面

mv /usr/local/pnp4nagios/share/install.php /usr/local/pnp4nagios/share/install.php.bak

如下：

如果需要在nagios页面即可查看到动态曲线那么需要做如下改动：

到pnp4nagios-0.6.24解压目录下

cp pnp4nagios-0.6.24/contrib/ssi/status-header.ssi /usr/local/nagios/share/ssi/

vim /usr/local/nagios/etc/objects/templates.cfg 
define host{
        name       host-pnp
        register   0
        action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_' class='tips' rel='/pnp4nagios/popup?host=$HOSTNAME$&srv=_HOST_
        process_perf_data 1
        }
define service{
        name       service-pnp
        register   0
        action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$' class='tips' rel='/pnp4nagios/popup?host=$HOSTNAME$&srv=$SERVICEDESC$  
        process_perf_data 1
        }

备注：

生成的rrd文件在此目录/usr/local/pnp4nagios/var/perfdata/localhost

如果因为网络不稳定导致出图问题，可以修改一下超时时间

vim /usr/local/pnp4nagios/etc/process_perfdata.cfg

TIMEOUT = 30 #默认是15秒
