# cat check_Mysql_custom.py

import os

try:
import MySQLdb as mysql
except Exception, e:

print "pip install MySQL-python"

假如执行测试时报以下错误：# python check_Mysql_custom.py slave_statusTraceback (most recent call last):File "test.py", line 14, in con = mysql.connect(user='zabbix',passwd='',port=3306)File "/usr/local/lib/python2.7/site-packages/MySQLdb/__init__.py", line 81, in Connect return Connection(*args, **kwargs)File "/usr/local/lib/python2.7/site-packages/MySQLdb/connections.py", line 193, in __init__ super(Connection, self).__init__(*args, **kwargs2)_mysql_exceptions.OperationalError: (2002, "Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)")

# mkdir /var/lib/mysql
# ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock
##测试一下脚本：
1

3
4
# python check_Mysql_custom.py processlist
3
# python check_Mysql_custom.py Connections
55876
##测试显示所有在mysql中show status的都可以输出信息出来：
##写一个模板配置文件（自定义key值）：
1
2
# cat Mysql_Custom.conf
UserParameter=mysql.Custom,/usr/local/bin/python /home/python/check_Mysql_custom.py $1
##在zabbix web界面上加入模板： ##增加一个Appaliactions:
##加入item值：
