Cacti监控

Cacti监控

1）cacti是用PHP语言实现的一个软件2）使用snmp服务获取数据，nnmp关系着数据的收集3）当用户需要查看数据的时候用rrdtool生成图表

搭建Cacti监控平台

1）部署Cacti服务运行环境LAMP/LNMP#yum -y install httpd php php-mysql mariadb#systemctl restart httpd#systemctl restart mariadb2)搭建cacti服务器#yum -y install rrdtool net-snmp-*    /安装依赖包  snmp 简单的网络管理协议#tar zxf cacti-0.8.8h.tar.gz#cp -r cacti-0.8.8h /var/www/html/cacti#chown apache:apache /var/www/html/cacti  /属主，属组为apache创建存储配置信息的库及表#create database cactidb;#grant all on cactidb.* to cacti@"localhost" identified by "123456"#mysql -ucacti -p123456 cactidb < /var/www/html/cacti/cacti.sql    /导入存储配置信息的表修改配置文件，设置存储配置信息使用的库/var/www/html/cacti/include/config.php$database_type = "mysql";             /类型为mysql数据库$database_default = "cactidb";       /库名为创建的cactidb$database_hostname = "localhost";   /数据库本地主机名 localhost$database_username = "cacti";       /登录数据库用户 cacti$database_password = "123456";$database_port = "3306";$database_ssl = false;安装数据高速采集器spine#yum -y install mariadb-devel#tar zxf cacti-0.8.8h.tar.gz#cd cacti-0.8.8h#./configure  --with-mysql     默认目录为/usr/local/spine#make#make install#cp usr/local/spine/etc/spine.conf.dist /etc/spine.conf#vim /etc/spine.confDB_Host         localhostDB_Database     cactidbDB_User         cactiDB_Pass         123456DB_Port         3306web页面上进行修改settings --> path --->Spine Poller File Path   /usr/local/spine/bin/spine ---> poller--->poller Type  spine

监控远端主机

a)配置被监控端[host17]#yum -y install net-snmp-*#sed -n '41p,62p,85p' /etc/snmp/snmpd.conf#systemctl restart snmpd#systemctl enable snmpdb)配置监控服务器1）添加监控主机 并选择监控模版web页面 --->Devices --->add--->host17/192.168.4.17/...--->save2）设置监控项3）创建图片Devices--->create Graphs for this Host4）创建图像树，并把监控主机的图片添加到图像数里Graph Trees--->add5）编写抓取数据的cron任务*/5 * * * * php /var/www/html/cacti/poller.php &> /dev/null#ls /var/www/html/cacti/rra -l

监控报警

1）安装插件: 解压并移动到插件目录下然后激活2）配置监控报警 要求: 对本机登录用户数做监控报警a)创建消息列表notification Listsb)设置监控报警项Thresholdsc)指定服务器setting---> Mail/DNS
