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）

ALTER TABLE `npc_notifications` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;

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：
