使用python写一个监控mysql的脚本，在zabbix web上自定义模板

Posted 2020-10-30

##先使用mysqldb的接口关联数据库。

[[email protected] python]# cat check_Mysql_custom.py
#!/usr/local/bin/python
'''author = chenmingle'''
'''Description:get mysql status'''
import os
import sys
try:
    import MySQLdb as mysql
except Exception, e:
    print e
    print "pip install MySQL-python"
    sys.exit(1)
con = mysql.connect(host='localhost',user='root',passwd='passwd',)
def processlist():
cur = con.cursor()
sql1 = 'show processlist'
a = str(cur.execute(sql1))
print a
def slave_status():
        cur = con.cursor()
        sql2 = cur.execute('show status like "%Slave_running%";')
        status2 = str(cur.fetchall())
        check2 = status2.split("'")[3]
        if check2 == 'ON':
                print 0
        else:
                print 1
def show_status(type):
cur = con.cursor()
b = cur.execute('show status like "%s";' %(type))
for i in cur.fetchall():
cat = str(i)
check = str(cat.split("'")[3])
print check
def main(type):
   if type == 'processlist':
processlist()
   elif type == 'slave_status':
slave_status()
   else:
show_status(type)
if __name__ == '__main__':
    try:
        type = sys.argv[1]
    except Exception, e:
        print "Usage: python %s type" % sys.argv[0]
        sys.exit(1)
    main(type)

假如执行测试时报以下错误：

[[email protected] python]# python check_Mysql_custom.py slave_status

Traceback (most recent call last):

  File "test.py", line 14, in <module>

    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)")

[[email protected] python]# mkdir /var/lib/mysql
[[email protected] python]# ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock

##测试一下脚本：

[[email protected] python]# python check_Mysql_custom.py processlist
3
[[email protected] python]# 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）：

[[email protected] zabbix_agentd.d]# 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：
