ICINGA项目是由Michael Luebben、Hendrik Backer和JoergLinge等人发起的，他们都是现有的Nagios项目社区委员会的成员，他们承诺，新的开源项目将完全兼容以前的Nagios应用程序及扩展功能。在新项目的网站上，他们是如此定义ICINGA的，这将是一个介于Nagios社区版和企业版间的产品。特别将致力于解决Nagios项目现在的问题，比如不能及时处理Nagios项目的bug、新功能不能及时添加等。还有在新的ICINGA项目中，将更好的实现数据库集成方面的功能，标准化第三发应用程序的接口等。

Tsar是淘宝的采集工具，主要用来收集服务器的系统信息（如cpu，io，mem，tcp等）以及应用数据（如squid haproxy nginx等），tsar支持实时查看和历史查看，方便了解应用和服务器的信息!

它类似于sar，能监控和收集服务器和关键应用的信息，支持实时终端显示和集中式数据库存储查询，还能向Nagios发送报警信息。Tsar模块化的设计利于通过开发新模块来扩展新的功能，非常方便。

1.模块化
Tsar的各个模块专门采集一类数据，通过配置文件和参数支持模块化，用户也可以根据需求编写自己的采集模块，集成到Tsar中即可生效
2.输出方式多样
支持本机查看
支持输出到远程数据库
配合nagios的被动监控，页面显示

由于需要用Nagios+Ganglia监控Hadoop集群,所以这里开始了Nagios+Ganglia的旅程.Nagios官网上资料已经很详尽,但在Ubuntu上安装Nagios方面,只停留在Ubuntu 6.10和Ubuntu 7.10版本.而在Ubuntu11.10或Ubuntu10.04上安装有些错误,所以这里记录下来.具体可以查看Nagios官网上Nagios在Ubuntu上安装说明:http://nagios.sourceforge.net/docs/3_0/quickstart-ubuntu.html

1.所依赖包:

1)Apache #必须安装

2)Php #必须安装

3)Gcc #必须安装

4)Gd #必须安装

5) mailx #可选,让Nagios支持邮件

6) postfix #可选,让Nagios支持邮件

以上可以通过dpkp -L apache2等查看,如未安装,请通过sudo apt-get install apache2等安装,具体如下:

sudo apt-get install apache2 # 安装Apache

sudo apt-get install php5 # 安装Php

sudo apt-get install libapache2-mod-php5 # 整合Apache+Php

sudo apt-get install build-essential # 安装Ubuntu编译内核

sudo apt-get install libgd2-xpm-dev # 安装Gd

sudo apt-get install mailx

sudo apt-get install postfix

2.开始安装

sudo -s # 切换到root

1) 设置好用户和用户组

/usr/sbin/useradd -m -s /bin/bash nagios # 添加用户nagios

passwd nagios # 给新用户nagios设置密码

/usr/sbin/groupadd nagios # 添加用户组nagios

/usr/sbin/usermod -G nagios nagios # 将新用户nagios添加到用户组nagios

/usr/sbin/groupadd nagcmd # 添加新的用户组nagcmd,用于接受外部命令,如通过web

/usr/sbin/usermod -a -G nagcmd nagios # 添加用户nagios到用户组nagcmd

/usr/sbin/usermod -a -G nagcmd www-data # 添加apache用户到用户组nagcmd

2)下载nagios和nagios-plugin

mkdir ~/downloads

cd ~/downloads

wget http://nchc.dl.sourceforge.net/project/nagiosplug/nagiosplug/1.4.15/nagios-plugins-1.4.15.tar.gz # 下载插件

wget http://nchc.dl.sourceforge.net/project/nagios/nagios-3.x/nagios-3.3.1/nagios-3.3.1.tar.gz #下载nagios

3)安装Nagios

cd ~/downloads

tar xzf nagios-3.3.1.tar.gz

cd nagios

./configure --with-command-group=nagcmd

make all

#make install #使用该命令会报错,替换成以下命令

./configure --with-command-group=nagcmd

sed -i 's:for file in includes/rss/\*;:for file in includes/rss/\*.\*;:g' ./html/Makefile

sed -i 's:for file in includes/rss/extlib/\*;:for file in includes/rss/extlib/\*.\*;:g' ./html/Makefile

make fullinstall

#以上避免了使用make install报错,报错内容查看博客结尾.具体原因不清楚,有知道的麻烦回帖告知.

make install-init #安装初始化,貌似make fullinstall有了安装,但无所谓

make install-config #安装配置

make install-commandmode #安装命令模式

4)自定义配置

vi /usr/local/nagios/etc/objects/contacts.cfg #在里面修改,如email

5)安装web接口,以便通过浏览器可以访问到nagios

make install-webconf

htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin #给nagios设置用户和密码

/etc/init.d/apache2 reload #重载,让新设置的用户和密码生效

6)编译nagios插件

cd ~/downloads

tar xzf nagios-plugins-1.4.15.tar.gz

cd nagios-plugins-1.4.15

./configure --with-nagios-user=nagios --with-nagios-group=nagios

make

make install

7)启动nagios

ln -s /etc/init.d/nagios /etc/rcS.d/S99nagios #让nagios随机启动

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg #验证naios配置文件是否正确

/etc/init.d/nagios start #启动nagios

8)通过浏览器进入nagios控制台

http://localhost/nagios/ #再输入刚配置的用户nagiosadmin和你设置的密码

最后附上用make install安装nagios时所报错误

被监控机安装nrpe

准备工作:
apt-get install openssl
apt-get install libcurl3-openssl-dev
apt-get install xinetd

下载:

http://prdownloads.sourceforge.net/sourceforge/nagios/nrpe-2.13.tar.gz

tar -zxf nrpe-2.13.tar.gz
cd nrpe-2.13

开始安装:
./configure
make all && make install-plugin && make install-daemon && make install-daemon-config
make install-xinetd

编辑 /etc/xinetd.d/nrpe 将nagios的服务器ip添加进去
将NRPE进程端口加到/etc/services中
nrpe 5666/tcp
重新启动xinetd服务
service xinetd restart

确认nrpe是否在xinetd下运行
netstat -at |grep nrpe

测试nrpe是否工作
/usr/local/nagios/libexec/check_nrpe -H localhost

服务器配置:

同样安装nrpe.

检查命令行是否可查到被监控主机nrpe信息:
/usr/local/nagios/libexec/check_nrpe -H 192.168.0.被监控

1:创建command定义

编辑/usr/local/nagios/etc/objects/commands.cfg增加以下配置信息

define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}

2:定义主机和服务设定

先建立一个模板用于之后的主机监控的继承设定(在/usr/local/nagios/etc/objects/templates.cfg已经有添加了这个模板规则，只是notification_period不一样而已，关于这个的解释也非常有意思可以自己看看)
define host{
name linux-server ; Name of this template
use generic-host ; Inherit default values
check_period 24×7
check_interval 5
retry_interval 1
max_check_attempts 10
check_command check-host-alive
notification_period 24×7
notification_interval 30
notification_options d,r
contact_groups admins
register 0 ; DONT REGISTER THIS – ITS A TEMPLATE
}

3:编辑/usr/local/nagios/etc/objects/localhost.cfg(也可以自己创建文件，只要在nagios.cfg中添加对应配置)

增加被监控的主机对象

define host{
use linux-server
host_name web-server ;nrpe check host
alias ubuntu server (WWW)
address 192.168.200.244
}

增加监控远程服务器的服务对象

define service{
use generic-service
host_name web-server
service_description CPU Load
check_command check_nrpe!check_load
}

define service{
use generic-service
host_name web-server
service_description Current Users
check_command check_nrpe!check_users
}

磁盘监控需要确认自己的硬盘是hda 还是sda，nrpe安装的默认配置是check_hda1，所以需要你手动修改被监控服务器的/usr/local/nagios/etc/nrpe.cfg，将hda修改为sda。并重新启动xinetd服务

define service{
use generic-service
host_name web-server
service_description /dev/sda1 Free Space
check_command check_nrpe!check_sda1
}

define service{
use generic-service
host_name web-server
service_description Total Processes
check_command check_nrpe!check_total_procs
}

define service{
use generic-service
host_name web-server
service_description Zombie Processes
check_command check_nrpe!check_zombie_procs
}

配置完成后，运行/etc/init.d/nagios checkconfig
或
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

安装nrpe时提示错误：configure: error: cannot find ssl headers

起首安装SSL库，openssl或者libssl：

sudo apt-get install openssl

sudo apt-get install libssl

configure的时辰加上选项：

./configure --with-ssl=/usr/bin/openssl --with-ssl-lib=/usr/lib/x86_64-linux-gnu（可能64位和32位有所不合）
