篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了zabbix监控windows mysql脚本报错相关的知识，希望对你有一定的参考价值。
报错提示Arg = objArgs(0)有问题，有大神知道怎么修改吗
这段代码是zabbix来监控windows上的mysql的
运行会报错，是因为运行的时候后面要加参数，比如加个 $1 这个参数
C:\\zabbix\\script> MySQL_Ext-Status_Script.vbs $1追问在zabbix配置里面有跟 $1，我用Power Shell执行脚本同样会报错。
zabbix自定义监控
zabbix自定义监控
开启自定义监控功能
在zabbix客户端上将zabbix_agent.conf文件中将自定义监控的功能打开
[root@client /]# vim /usr/local/etc/zabbix_agentd.conf
UnsafeUserParameters=1 //0表示此功能关闭1表示此功能打开
在两台被监控的主机上创建脚本存放目录
[root@client ~]# mkdir /scripts
自定义监控进程
编写判断进程是否开启的脚本
[root@client ~]# vim /scripts/check_process.sh
#!/bin/bash
process_status=$(ps -elf | grep -Ev "grep|$0" | grep -c $1)
if [ $process_status != 0 ];then
echo '1'
else
echo '0'
fi
给脚本加执行权限
[root@client ~]# chmod +x /scripts/check_process.sh
测试zabbix用户是否能使用此脚本
[root@client ~]# ss -anlt

try:
tagKey = str(sys.argv[3])

return tagKey
def getResult(filename,seekfile,tagkey):
destPos = prePos(seekfile)

curpos = 0
try:
f = open(filename)
except IOError:
print('Could not open file: %s' % filename)
except FileNotFoundError:
print('Could not open file: %s' % filename)
else:
f.seek(destPos)
while curPos != 0 and f.tell() < curPos:
rresult = f.readline().strip()
global result
if re.search(tagkey, rresult):
result = 1
break
else:
result = 0

sf.write(str(curPos))

f.close()
return result

mysql主从状态的监控
实验环境说明：
| 主机名：主机IP | 角色 |
|---|---|
| zabbix：192.168.247.215 | zabbix_server端 |
| client：192.168.247.211 | zabbix_agent端、mysql从数据库 |
| client1：192.168.247.214 | mysql主数据库 |
配置主数据库的root账号在从数据库可以远程登录且不需要密码
client1：
mysql> create user 'root'@'192.168.247.211' identified by 'hanao.';
mysql> grant all on *.* to 'root'@'192.168.247.211';
Query OK, 0 rows affected (0.01 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
client：
[root@client ~]# vim /etc/my.cnf
[mysqld]
basedir = /usr/local/mysql
datadir = /opt/mysql_data
socket = /tmp/mysql.sock
port = 3306
pid-file = /opt/mysql_data/mysql.pid
user = mysql
skip-name-resolve
server-id=2
relay-log=slave_relay_bin
[client]
user=root
password=hanao.
编写判断主从状态的脚本
client:
[root@client ~]# vim /scripts/check_mysql_replistatus.sh

status=$(mysql -e 'show slave status\\G' | grep "Running: Yes" |awk '{print $2}' | grep -c 'Yes')
if [ $status == 2 ];then
echo '0'
else
echo '1'
