zabbix--监控MySQL性能

Zabbix 自带模板监控 MySQL 性能

经过自带的 Template DB MySQL 模板监控 MySQL 性能mysql

具体步骤:sql

1)建立脚本存放目录并编辑脚本数据库

# mkdir /etc/zabbix/script
# vim /etc/zabbix/script/mysql_status.sh //编辑脚本 #!/bin/bash #Desc:zabbix 监控 MySQL 状态 #Date:2019-5-6 #by:Lee-YJ #主机 HOST="localhost" #用户 USER="root" #密码 PASSWORD="IjRMv3l6TQIEjvb9nIX5" #端口 PORT="3306" #MySQL链接 CONNECTION="mysqladmin -h ${HOST} -u ${USER} -P ${PORT} -p${PASSWORD}"

if [ $# -ne "1" ];then
    echo "arg error!"
fi

case $1 in Uptime) result=`${CONNECTION} status 2>/dev/null |awk '{print $2}'` echo $result ;; Questions) result=`${CONNECTION} status 2>/dev/null |awk '{print $6}'` echo $result ;; Com_update) result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_update" |awk '{print $4}'` echo $result ;; Slow_queries) result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Slow_queries" |awk '{print $4}'` echo $result ;; Com_select) result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_select" |awk '{print $4}'` echo $result ;; Com_rollback) result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_rollback" |awk '{print $4}'` echo $result ;; Com_insert) result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_insert" |awk '{print $4}'` echo $result ;; Com_delete) result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_delete" |awk '{print $4}'` echo $result ;; Com_commit) result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_commit" |awk '{print $4}'` echo $result ;; Bytes_sent) result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Bytes_sent" |awk '{print $4}'` echo $result ;; Bytes_received) result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Bytes_received" |awk '{print $4}'` echo $result ;; Com_begin) result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_begin" |awk '{print $4}'` echo $result ;;*) echo "Usage:$0(Uptime|Questions|Com_update|Slow_queries|Com_select|Com_rollback|Com_insert|Com_delete|Com_commit|Bytes_sent|Bytes_received|Com_begin)" ;; esac
# chmod +x /etc/zabbix/script/mysql_status.sh //给脚本赋予执行权限

2)修改zabbix-agent配置文件,默认有一个MySQL的子配置文件,直接编辑该文件便可vim

# vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf #获取MySQL性能指标,这个是上一步编辑好的脚本 UserParameter=mysql.status[*],/etc/zabbix/script/mysql_status.sh $1 #获取MySQL运行状态 UserParameter=mysql.ping,mysqladmin -u root -h localhost -pIjRMv3l6TQIEjvb9nIX5 ping 2>/dev/null | grep -c alive #获取MySQL版本 UserParameter=mysql.version,mysql -V

3)重启 zabbix-agent bash

# service zabbix-agent restart

4)Web界面配置、点击须要配置的主机,进去添加连接模板,自带的Template DB MySQLide

5)配置完成后等一下子就能够查看到监控主机的MySQL监控信息性能

说明:若是发现监控没有数据,请排查以下问题code

1. zabbix客户端是否重启
2. 脚本是否有执行权限
3. 数据库是否有权限
4. 环境变量是否有问题

 

附 agent 端自动配置脚本
