zabbix監控mysql效能的配置教程

通過擷取mysql狀態值將這些狀態值傳遞給伺服器並繪製成圖片，這樣可以觀察mysql的工作情況，通常需要獲得狀態變數有以下

Com_update：mysql執行的更新個數
Com_select：mysql執行的查詢個數
Com_insert：mysql執行插入的個數
Com_delete：執行刪除的個數
Com_rollback：執行復原的操作個數
Bytes_received:接受的位元組數
Bytes_sent：發送的位元組數
Slow_queries：慢查詢語句的個數

1、建立mysql效能監控指令碼

#!/bin/bash
#Create by zhengdazhi 2014.09.22
MYSQL_DIR=/usr/local/mysql
MYSQL=${MYSQL_DIR}/bin/mysql
MYSQLADMIN=${MYSQL_DIR}/bin/mysqladmin
MYSQL_SOCK="/tmp/mysql.sock"
MYSQL_USER=root
MYSQL_PWD=root
 
ARGS=1
if [ $# -ne "$ARGS" ];then
    echo "Please input one arguement:"
fi
case $1 in
    Uptime)
        result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK status|cut -f2 -d":"|cut -f1 -d"T"`
            echo $result
            ;;
        Com_update)
            result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_update"|cut -d"|" -f3`
            echo $result
            ;;
        Slow_queries)
        result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK status |cut -f5 -d":"|cut -f1 -d"O"`
                echo $result
                ;;
    Com_select)
        result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_select"|cut -d"|" -f3`
                echo $result
                ;;
    Com_rollback)
        result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_rollback"|cut -d"|" -f3`
                echo $result
                ;;
    Questions)
        result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK status|cut -f4 -d":"|cut -f1 -d"S"`
                echo $result
                ;;
    Com_insert)
        result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_insert"|cut -d"|" -f3`
                echo $result
                ;;
    Com_delete)
        result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_delete"|cut -d"|" -f3`
                echo $result
                ;;
    Com_commit)
        result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_commit"|cut -d"|" -f3`
                echo $result
                ;;
    Bytes_sent)
        result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Bytes_sent" |cut -d"|" -f3`
                echo $result
                ;;
    Bytes_received)
        result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Bytes_received" |cut -d"|" -f3`
                echo $result
                ;;
    Com_begin)
        result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_begin"|cut -d"|" -f3`
                echo $result
                ;;
 
        *)
        echo "Usage:$0(Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions)"
        ;;
esac

2、修改用戶端設定檔

查看zabbix內建的mysql監控模板

截圖00

可以看出該模板是讀取 mysql.status的鍵，因此在用戶端設定檔中加入的自訂鍵名也應該是mysql.status

vim /usr/local/zabbix_agentd/etc/zabbix_agentd.conf
#開啟使用者自訂配置
UnsafeUserParameters=1
#添加mysql監控
UserParameter=mysql.status[*],/usr/local/zabbix_agent/bin/checkmysqlperformance.sh $1 $2
重啟用戶端
3、測試
[root@localhost bin]# ./zabbix_get -s 127.0.0.1 -k mysql.status[Com_update]
