zabbix--監控MySQL性能

Zabbix 自帶模板監控 MySQL 性能

經過自帶的 Template DB MySQL 模板監控 MySQL 性能

具體步驟：

1）建立腳本存放目錄並編輯腳本

# mkdir /etc/zabbix/script

# vim /etc/zabbix/script/mysql_status.sh //編輯腳本 #!/bin/bash #Desc：zabbix 監控 MySQL 狀態 #Date：2019-5-6 #by：Lee-YJ #主機 HOST="localhost" #用戶 USER="root" #密碼 PASSWORD="IjRMv3l6TQIEjvb9nIX5" #端口 PORT="3306" #MySQL鏈接 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 //給腳本賦予執行權限

2）修改zabbix-agent配置文件，默認有一個MySQL的子配置文件，直接編輯該文件便可

# vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf #獲取MySQL性能指標，這個是上一步編輯好的腳本 UserParameter=mysql.status[*],/etc/zabbix/script/mysql_status.sh $1 #獲取MySQL運行狀態 UserParameter=mysql.ping,mysqladmin -u root -h localhost -pIjRMv3l6TQIEjvb9nIX5 ping 2>/dev/null | grep -c alive #獲取MySQL版本 UserParameter=mysql.version,mysql -V

3）重啓 zabbix-agent 

# service zabbix-agent restart

4）Web界面配置、點擊須要配置的主機，進去添加連接模板，自帶的Template DB MySQL

5）配置完成後等一下子就能夠查看到監控主機的MySQL監控信息

 查看監控主機的 MySQL bandwidth 圖形

查看監控主機的 MySQL operations 圖形

說明：若是發現監控沒有數據，請排查以下問題

1. zabbix客戶端是否重啓
2. 腳本是否有執行權限
3. 數據庫是否有權限
4. 環境變量是否有問題

 

附 agent 端自動配置腳本
