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_alertconta
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(s) --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,默认每天查一次数据库(自己可以指定),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
