Database System Alert contact API

 

When we maintain the system, we need to transmit the system's alarm information to the corresponding students in real time. If we directly write the contact information in the script, it will cause future maintenance changes, in particular, hundreds of systems.
For this reason, an API is provided to obtain contact information.

Database Configuration center table:

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;

Usage help:
[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] #

Example:

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, '123', 'phone', 'skate3 ', 'p2 '),
(4, 1, '000000', 'phone', 'skate', 'p2 '),
(5, 1, '000000', '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

Advantages:
1. You do not need to modify the code when changing the contact or contact information.
2. the contact information is stored in the configuration center database. To reduce the number of queries to the database, the database is queried once a day by default (you can specify the contact information yourself), which improves the speed, reduces the dependency on the configuration center.
3. If you want the change contact information to take effect immediately, you only need to delete the local temporary file "/tmp/contact_dbinfo ".
