Zabbix监控

1.zabbix监控日志文件配置

[root@localhost ~]# mkdir /scripts/
[root@localhost ~]# mv log.py /scripts/
mv: 无法获取"log.py" 的文件状态(stat): 没有那个文件或目录
[root@localhost ~]# cd pyscripts-master/
[root@localhost pyscripts-master]# mv log.py /scripts/
[root@localhost pyscripts-master]# ls
[root@localhost pyscripts-master]# cd
[root@localhost ~]# ls
anaconda-ks.cfg   pyscripts-master.zip  zabbix-5.0.2.tar.gz
pyscripts-master  zabbix-5.0.2
[root@localhost ~]# cd /scripts/
[root@localhost scripts]# ls
log.py
[root@localhost scripts]# pwd
/scripts
[root@localhost scripts]# vim /usr/local/etc/zabbix_agentd.conf
[root@localhost scripts]# tail /usr/local/etc/zabbix_agentd.conf

[root@localhost scripts]# 

2.mysql主从监控

2.1配置主库

[root@localhost ~]# mysql

MariaDB [(none)]> 

[root@localhost scripts]# vim mysql.sh    //编写脚本

#!/bin/bash

mysql=$(mysql -e 'show slave status \G'| grep Slave.*Running: | grep -co 'Yes')

if [ $mysql -eq 2 ];then
    echo '0'
else
    echo '1'
fi

[root@localhost scripts]# chmod +x mysql.sh 
[root@localhost scripts]# vim /usr/local/etc/zabbix_agentd.conf
UserParameter=lzlz[*],/bin/bash /scripts/mysql.sh

3.监控数据库主从延迟

[root@localhost scripts]# vim mysql_delayed.sh 
[root@localhost scripts]# bash mysql_delayed.sh 
0
[root@localhost scripts]# cat mysql_delayed.sh 
#!/bin/bash

delay_value=$(mysql -e 'show slave status\G' 2>/dev/null|grep 'Seconds_Behind_Master' | awk -F'[: ]+' '{print $3}')

if [ $delay_value -eq 0 ];then
    echo '0'
else 
    echo '1'
fi

[root@localhost scripts]# vim /usr/local/etc/zabbix_agentd.conf  

UserParameter=mysql_delayed,/bin/bash /scripts/mysql_delayed.sh   //添加这一行

4.监控时可以加声音
