      	check_command                   check_tcp!80//检查的命令 commands.cfg 配置
}

2、定义主机的配置文件
hosts.conf

define host {
        host_name                test         //主机名名字
        alias                        test_host_group //主机别名
        address                 10.168.1.100 //主机IP
        contact_groups        gjw_apparitor//联系组 contacts.cfg配置
        check_period                            24x7        //检查时间 timeperiods.cfg配置
        max_check_attempts              3        //最大尝试次数，建议2～3次
        normal_check_interval         5         //正常检查的间隔/分
        retry_check_interval         2        //重试检查的间隔/分
        notification_interval           10        //报警的间和时间/分
        notifications_enabled                  1         //启用主机事件通知
        event_handler_enabled           1        //启用主机事件处理程序
        flap_detection_enabled         1        //启用状态抖动监测
        failure_prediction_enabled     1        //启用故障预测
        process_perf_data                       1        //启用进程性能数据记录
        retain_status_information      1        //启用状态信息保存功能
        retain_nonstatus_information       1        //启用非状态信息保存功能
        notification_period                     24x7        //报警的时间 timeperiods.cfg配置
        notification_options               d,u,r        //报警的状态：d—宕机(down),u—未知(unkown),或者r—从异常情况恢复正常。
        check_command                   check-host-alive//检查的命令 commands.cfg 配置

}

3、定义主机组的配置文件

hostgroup.cfg

define hostgroup {
        hostgroup_name               test_group              //组名字
        alias                           xxx_test_group       //组别名
        members                      test                   //主机名，多写以“，”号分割。
}

4、定义联系人的配置文件

contacts.cfg

define contact{
        contact_name                 test_name            //联系人名字
        alias                        test_name_admin      //联系人别名
        service_notification_period     24x7              //主机报警时间 timeperiods.cfg配置
        host_notification_period        24x7             //服务报警时间 timeperiods.cfg配置
        service_notification_options    w,u,c,r,f,s      //报警的状态：w—报警(warning),u—未知(unkown),c—严重(critical),或者r—从异常情况恢复正常
        host_notification_options       d,u,r,f,s       //报警的状态：d—宕机(down),u—未知(unkown),或者r—从异常情况恢复正常。
        service_notification_commands   notify-service-by-email         //服务报警类型（邮件）
        host_notification_commands      notify-host-by-email           //主机报警类型（邮件）
        email                           gjw.apparitor@gmail.com        //邮件地址
        pager                           13810000000                    //手机号
}

define contactgroup{
contactgroup_name gjw_apparitor    //联系组名字
aliasnagios Admin                  //联系组别名
memberstest_name                   //联系人名字，多写以“，”号分割。
}

1、nginx编译时允许http_stub_status_module
2、修改nginx配置文件

0
1
2
3
4
5
6
7
8
9

 # vi nginx.conf
server {
……
……
        location /NginxStatus {
        stub_status on;
        allow 192.168.8.8;#允许cacti IP 访问    
             access_log off;
       }
}

3、nginx配置文件生效

# kill -HUP `cat /usr/local/nginx/logs/nginx.pid`


二、cacti上安装插件
1、下载cacti for nginx 插件包： http://www.oschina.net/uploads/code/cacti-nginx.tar.gz

# tar zxvf cacti-nginx.tar.gz
# cd cacti-nginx
# chown -R cacti. *.pl
# cp *.pl /www/WEB/www/cacti/scripts/

导入的方式是 Import Templates > Import Template from Local File (浏览导入插件包另外2个文件)
cacti_graph_template_nginx_clients_stat.xml
cacti_graph_template_nginx_sockets_stat.xml
导入 cacti_graph_template_nginx_clients_stat.xml 跟 cacti_graph_template_nginx_sockets_stat.xml 的时候，

cacti 出现红字提醒：
Error: XML: Hash version does not exist.

解决：因为你的 cacti 版本太旧了，去Cacti 下个最新版吧：http://www.cacti.net/download_cacti.php

安装 RRDTOOL
rrdtool 1.2.x以后不用GD画图了。用freetype 和 libart_lgpl
所以不用在安装GD了
代码:

# BUILD_DIR=/gjw/rrdbuild
# INSTALL_DIR=/usr/local/rrdtool-1.2.30
# set BUILD_DIR=/gjw/rrdbuild
# set INSTALL_DIR=/usr/local/rrdtool-1.2.30
# mkdir -p $BUILD_DIR

# cd $BUILD_DIR
# wget http://oss.oetiker.ch/rrdtool/pub/libs/libart_lgpl-2.3.17.tar.gz
# tar zxvf libart_lgpl-2.3.17.tar.gz
# cd libart_lgpl-2.3.17
# env CFLAGS=”-O3 -fPIC” ./configure –disable-shared –prefix=$BUILD_DIR/lb
# make
# make install
# ranlib $BUILD_DIR/lb/lib/*.a
# IR=-I$BUILD_DIR/lb/include
# CPPFLAGS=”$IR $IR/libart-2.0 $IR/freetype2 $IR/libpng”

# ./configure –prefix=$INSTALL_DIR –disable-python –disable-tcl
# make clean
# make
# make install
# cat rrdtool-1.2.30/doc/rrdbuild.txt

这个文档就是安装rrdtool的说明

安装 net-snmp
NET-SNMP 官方网站:http://www.net-snmp.org/
代码:

# cd /software/cacti
# wget http://nchc.dl.sourceforge.net/sourceforge/net-snmp/net-snmp-5.4.2.1.tar.gz
# tar zxvf net-snmp-5.4.2.1.tar.gz
# cd net-snmp-5.4.2.1
# ./configure –prefix=/data_server/net-snmp –enable-developer
# make
# make install
# ln –s /data_server/net-snmp/bin/* /usr/local/bin/

安装 cacti
代码:

# wget http://www.cacti.net/downloads/cacti-0.8.7d.tar.gz
# tar zxvf cacti-0.8.7d.tar.gz
# cd cacti-0.8.7d
# useradd cacti
# mysqladmin -uroot -p create cacti
# mysql -uroot -p cacti < cacti.sql
# mysql -uroot -p

GRANT ALL ON cacti.* TO cacti@localhost IDENTIFIED BY ‘cacti’;
flush privileges;
quit
# vi include/config.php

$database_default = “cacti”;
$database_hostname = “127.0.0.1″;
$database_username = “cacti”;
$database_password = “cacti”;
-0.8.7d
# cp -r cacti-0.8.7d/ /data11/www 复制到你的apache的访问目录
# chown -R cacti:cacti /data11/www/cacti/
用浏览器打开http://ip/cacti/

name:admin
passwd:admin
之后会提示更改密码。修改后可以进入cacti了。

安装 cacti 插件

1、编译squid
编译Squid加上 –enable-snmp 支持snmp

2、# vi squid.conf 在配置文件加上。
acl CactiHost src 10.168.1.215
acl SNMP snmp_community Squid_snmp
snmp_port 3401
snmp_access allow SNMP CactiHost
snmp_access deny all
—————————-
注释：
acl CactiHost src 10.168.1.215 ＃定义允许snmp探测的机器IP
acl SNMP snmp_community Squid_snmp ＃设置snmp的 community
snmp_port 3401 # 监听的端口
snmp_access allow SNMP CactiHost
snmp_access deny all

3、测试。再cacti上运行
＃ snmpwalk -v 1 -c Squid_snmp 10.168.1.48:3401 .1.3.6.1.4.1.3495.1

4、添加模板

http://forums.cacti.net/download/file.php?id=79

unzip SquidStats-0.1.zip
mv webcache_squid_*.xml cacti_Path/resource/snmp_queries/
打开cacti的WEB
Console -> Import Templates -> 选择文件
导入cacti_host_template_webcache_squid_server_snmp.xml 保存

5、添加监控
Host Template 里选择 WebCache – Squid-Server(SNMP)
在 Downed Device Detection 选项中不要选择带有snmp的选项。
Ping Method 着个可以随便选择。
SNMP Version 选择 Version 1
SNMP Port 选择 3401

其他的按照你的配置填。
