Cacti监控MYSQL

-—cacti下mysql插件的安装

关于cacti 的安装配置，见之前的博文，本文接上篇cacti 短信报警外链网址已屏蔽

1.下载插件到/downloads目录

插件见附件

2.解压缩

Cd /downloads

Tar xvf mysql-cacti-templates-1.1.2.tar

3.拷贝mysql插件到scripts目录

Cd /var/www/localhost/htdocs/cacti/

Cp /downloads/mysql-cacti-templates-1.1.2/ss_get_mysql_stats.phpscripts/.

4.修改ss_get_mysql_stats.php

Vi ss_get_mysql_stats.php$mysql_user = ‘cactiuser’;

$mysql_pass = ‘cactipass’;

……

$cache_dir= ‘/var/www/localhost/htdocs/cacti/cache’;

5.创建cach_dir目录，并赋予最大权限

Mkdir cache

Chmod 777 –R cache

Chown –R cactiuser:cactiuser cache

6.赋予cactiuser对数据库的数据采集权限mysql -uroot -proot

Welcome to the MySQL mands end with ; or \g.

Your MySQL connection id is 129

Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the current input statement.

mysql>\q

测试：

Mysql –ucactiuser –pcactipass –h localhost

PhpMyadmin下看权限

7.打开IE访问Cacti 网址

8.导入mysql监控模板

Consoleàimport templatesà浏览, 选择刚才解压文件中的

cacti_host_template_x_db_server_ht_0.8.6i.xml，点击import导入

$A175124096-28561.png\_small.png$

Consoleàgraph templates，我们会看到如下图选项，导入成功。

9.添加一台有Mysql 服务的主机测试，主机需要安装net-snmp服务，添加方法

Console à devices àadd 出现如下界面，添加方法和普通主机一样，唯一的区别是Host Template中选择X DB Server HT(不选也行以后再添加，MYSQL监控表格比较多，以后添加比较麻烦)，

然后将这台刚才添加的主机添加到graph tree里面，这样我们就可以去看监控图片了

时间比较短，只能贴张1小时的图片

10.遇到问题

10.1 日志报错08/19/2013 11:55:05 PM - CMDPHP: Poller[0] ERROR: A DB Exec Failed!, Error:’1062’, SQL:”insert into poller_output (local_data_id, rrd_name, time, output) values (7, ‘proc’, ‘2013-08-19 23:55:04’, ‘88’)’

08/19/2013 11:55:04 PM - CMDPHP: Poller[0] ERROR: A DB Exec Failed!, Error:’1062’, SQL:”insert into poller_output (local_data_id, rrd_name, time, output) values (6, ‘users’, ‘2013-08-19 23:55:04’, ‘1’)’

解决方法：

chmod 755 –R log rra

chown cactiuser:cactiuser –R log rra

不过做完以后日志的purge权限没了

10.2日志一堆警告08/19/2013 11:45:04 PM - CMDPHP: Poller[0] Host[34] Description[MySQLtest01] DS[376] Graphs[‘MySQLtest01 - InnoDB Buffer Pool Activity’] WARNING: Result from CMD not valid. Partial Result: Can’t connect to MyS

08/19/2013 11:45:04 PM - CMDPHP: Poller[0] Host[34] Description[MySQLtest01] DS[381] Graphs[‘MySQLtest01 - MySQL Sorts’] WARNING: Result from CMD not valid. Partial Result: Can’t connect to MyS

其实日志已经说得很明白了，不能连接到MYSQL服务器，可惜我还是找了大半天，原来我的/include/config.inc默认密码是cactiuser，而这里设置的是cactipass，修改一样就可以了
