NPC就是Nagios Plugin for Cacti

cacti+nagios+ganglia cacti,nagios,ganglia整合:(在之前部署好各个监控的条件下) 需要下载这几个包：npc-2.0.4.tar.gz ndoutils-1.5.2.tar.gz ##npc是cacti的一个插件 nagios培训 Installing NPC ：
tar zxf npc-2.0.4.tar.gz -C /var/www/html/cacti/plugins Nagios Command File Path /usr/local/nagios/var/rw/nagios.cmd cacti界面plugin安装激活npc，并进行一下设置： Configuring Nagios ： tar zxf ndoutils-1.5.2.tar.gz ##ndoutils是一个模块 cd ndoutils-1.5.2 ./configure && make vim /usr/local/nagios/etc/nagios.cfg broker_module=/usr/local/nagios/bin/ndomod.o config_file=/usr/local/nagios/etc/ndomod.cfg nagios实施 添加模块：
cd ndoutils-1.5.2/src cp ndomod-3x.o /usr/local/nagios/bin/ndomod.o chmod +x /usr/local/nagios/bin/ndomod.o ##添加可执行权限 chown nagios.nagios /usr/local/nagios/bin/ndomod.o ##添加用户和用户组 cp ndo2db-3x /usr/local/nagios/bin/ndo2db chmod +x /usr/local/nagios/bin/ndo2db chown nagios.nagios /usr/local/nagios/bin/ndo2db cd ndoutils-1.5.2/config cp ndo2db.cfg-sample /usr/local/nagios/etc/ndo2db.cfg 监控软件
chmod +x /usr/local/nagios/etc/ndo2db.cfg chown nagios.nagios /usr/local/nagios/etc/ndo2db.cfg cp ndomod.cfg-sample /usr/local/nagios/etc/ndomod.cfg chmod +x /usr/local/nagios/etc/ndomod.cfg chown nagios.nagios /usr/local/nagios/etc/ndomod.cfg vim /usr/local/nagios/etc/ndo2db.cfg socket_type=tcp #socket_type=tcp tcp_port=5668 db_name=cacti db_prefix=npc_ #以npc开头的表 db_user=cacti db_pass=123 debug_verbosity=1 若忘记cacti密码， vim /var/www/html/cacti/include/config.php查看。 nagios配置 vim /usr/local/nagios/etc/ndomod.cfg
output_type=tcpsocket output=127.0.0.1 以npc开头的表里没有字段 `long_output` add.sql 根据nagios版本以及各插件版本的不同可编辑
nagios高于4.0(包括） [ /leeypp1/blog/293678#]?

把这个字段添加到cacti仓库 mysql -p123 cacti < add.sql 开启ndo2db： /usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg 把开启程序写到开机文件里 vim /etc/rc.local /usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg /etc/init.d/nagios reload 如果没有问题的话，cacti和nagios（nagios已经和ganglia整合）就出现在同一界面，如下图：
