zabbix自定义监控（mysql主从状态和延迟）

zabbix自定义监控

需要先配置mysql主从，从库上需要安装zabbix_agentd
zabbix_server配置
zabbix_agentd配置
mysql主从配置

监控mysql主从状态

主从同步完成

[root@localhost ~]# mysql -uroot -p123456 -e "show slave status\G"*************************** 1. row ***************************                Slave_IO_State: Waiting for master to send event                   Master_Host: 192.168.111.139                   Master_User: repl                   Master_Port: 3306                 Connect_Retry: 60               Master_Log_File: mysql_bin.000001           Read_Master_Log_Pos: 328                Relay_Log_File: myrela.000002                 Relay_Log_Pos: 555         Relay_Master_Log_File: mysql_bin.000001              Slave_IO_Running: Yes             Slave_SQL_Running: Yes

需要监控的是IO和SQL

配置监控脚本

#在被监控端，也是从库端，编写一个脚本测试[root@localhost ~]# mysql -uroot -p123456 -e "show slave status\G"|egrep -w "Running|Yes"|awk '{print $2}'|wc -l2[root@localhost ~]# cd /scripts/[root@localhost ~]# vim mysql_status.sh[root@localhost scripts]# chmod +x mysql_status.sh [root@localhost scripts]# ./mysql_status.sh 0#在被监控端，也是从库端，修改配置文件[root@localhost ~]# vim /usr/local/etc/zabbix_agentd.confUserParameter=check_mysql_status,/bin/bash /scripts/mysql_status.sh#!/bin/bashcount=$(mysql -uroot -p123456 -e "show slave status\G"|egrep -w "Running|Yes"|awk '{print $2}'|wc -l)if [ $count == 2 ];then    echo '0'else    echo '1'fi#重启zabbix_agentd[root@localhost ~]# pkill zabbix[root@localhost ~]# zabbix_agentd #服务端测试[root@zabbix ~]# zabbix_get -s 192.168.111.137 -k check_mysql_status0

添加监控项

添加触发器

手动触发报警

[root@localhost ~]# mysql -uroot -p123456 -e "stop slave"

监控mysql主从延迟

#在被监控端，也就是从库，编写脚本[root@localhost ~]# vim /scripts/mysqlyc.sh#!/bin/bashyc=`mysql -uroot -p123456 -e "show slave status\G" 2> /dev/null |awk '/Seconds_Behind_Master/ {print $2}' `echo $yc[root@localhost ~]# chmod +x /scripts/mysqlyc.sh#在被监控端，也就是从库，修改配置文件[root@localhost ~]# vim /usr/local/etc/zabbix_agentd.confUserParameter=check_mysqlyc,/bin/bash /scripts/mysqlyc.sh#重启zabbix_agentd[root@localhost ~]# pkill zabbix[root@localhost ~]# zabbix_agentd #服务端测试[root@zabbix ~]# zabbix_get -s 192.168.111.137 -k check_mysqlyc0
