DB系统预警联系人API
在我们维护系统时，需要把系统的报警信息即时传递给相应同学，如果把联系方式直接写到脚本里，对以后的维护变更将埋下祸根，尤其是成百上千的系统。
为此这里写了个获取联系人信息的API
数据库配置中心表：
CREATE TABLE `db_alertcontact` (
`id` INT(11) NULL DEFAULT NULL,
`levelid` INT(11) NULL DEFAULT NULL COMMENT ‘contact level‘,
`contact` VARCHAR(50) NULL DEFAULT NULL COMMENT ‘email or phone information‘,
`type` VARCHAR(50) NULL DEFAULT NULL COMMENT ‘phone/email‘,
`username` VARCHAR(100) NULL DEFAULT NULL,
`group` VARCHAR(80) NULL DEFAULT NULL COMMENT ‘contact group‘
)
COLLATE=‘utf8_general_ci‘
ENGINE=InnoDB;
CREATE TABLE `db_alertlevel` (
`id` INT(11) NULL DEFAULT NULL,
`levelname` VARCHAR(50) NULL DEFAULT NULL COMMENT ‘info/warn/err‘
)
COLLATE=‘utf8_general_ci‘
ENGINE=InnoDB;
用法帮助：
[root@skatedb55 pytest]# python contactlist.py --help
usage: Contanct API v0.1 ,(C) Copyright Skate 2014 [-h] --group GROUP --type
TYPE --level LEVEL
[--interval INTERVAL]
[--load LOAD]
optional arguments:
-h, --help show this help message and exit
--group GROUP = The contact group
--type TYPE = The mode of contact
--level LEVEL = alarm level,info/warn/err
--interval INTERVAL = Database query interval
--load LOAD = The configure center database,eg:
load=user/pass@ip:port:dbname
[root@skatedb55 pytest]#
例子：
INSERT INTO `db_alertcontact` (`id`, `levelid`, `contact`, `type`, `username`, `group`) VALUES
(1, 1, ‘skate1@163.com‘, ‘email‘, ‘skate1‘, ‘p1‘),
(2, 2, ‘skate2@163.com‘, ‘email‘, ‘skate2‘, ‘p2‘),
(3, 1, ‘1300000000‘, ‘phone‘, ‘skate3‘, ‘p2‘),
(4, 1, ‘1311111111‘, ‘phone‘, ‘skate4‘, ‘p2‘),
(5, 1, ‘1322222222‘, ‘phone‘, ‘skate5‘, ‘p2‘),
(6, 2, ‘skate6@163.com‘, ‘email‘, ‘skate6‘, ‘p2‘);
INSERT INTO `db_alertlevel` (`id`, `levelname`) VALUES
(1, ‘info‘),
(2, ‘warn‘),
(3, ‘error‘);
[root@skatedb55 pytest]# python contactlist.py --group=p2 --type=phone --level=info --interval=10--load=root/root@10.20.0.55:3306:test6
1300000000,1311111111,1322222222,
[root@skatedb55 pytest]#
[root@skatedb55 pytest]# python contactlist.py --group=p2 --type=email --level=warn --interval=10--load=root/root@10.20.0.55:3306:test6
skate2@163.com,skate6@163.com,
[root@skatedb55 pytest]#
优点：
1.在变更联系人或联系方式不需要修改代码
2.联系人的相关信息存储在配置中心数据库，为了减少对数据库的查询,每天查一次数据库，把联系信息放在本地，既提高了速度，也减少了对配置中心的依赖
3.如果想在变更联系信息及时生效，只需把本地的临时文件"/tmp/contact_dbinfo"删除即可
