zabbix监控之mysql监控

应用背景：

    生产环境中对mysql是否存活、版本、主从状态等监控是必不可少的，所以做了如下监控

 

zabbix_agent配置中添加如下:

#mysqldb status
UserParameter=mysql.version,/usr/local/mysql/bin/mysql -V
UserParameter=mysql.ping,/usr/local/mysql/bin/mysqladmin -S /data/mysqldata/mysql.sock ping | grep -c alive
UserParameter=mysql.status[*],/usr/local/zabbix-agent/bin/checkmysqlperformance.sh $1 $2
UserParameter=mysql.slave,/usr/local/zabbix-agent/bin/checkmysqlslave.sh |grep OK -c

 

脚本checkmysqlperformance.sh，监控数据库表和进程状态 如下：

#!/bin/bash
MYSQL_SOCK="/data/mysqldata/mysql.sock"
ARGS=1
if [ $# -ne "$ARGS" ];then
echo "Please input one arguement:"
fi
case $1 in
Uptime)
result=`/usr/local/mysql/bin/mysqladmin -S $MYSQL_SOCK status|cut -f2 -d":"|cut -f1 -d"T"`
echo $result
;;

echo $result
;;

echo $result

echo $result

echo $result

脚本checkmysqlslave.sh,监控数据库主从状态

#!/bin/bash
declare -a slave_is
slave_is=($(/usr/local/mysql/bin/mysql -e "show slave status\G"|grep -E "Slave_IO_Running|Slave_SQL_Running:"|awk '{print $2}'))
if [ "${slave_is[0]}" = "Yes" -a "${slave_is[1]}" = "Yes" ];then
echo "OK -slave is running"
exit 0
else
echo "Critical -slave is error"
exit 2
fi
