zabbix監控mysql

zabbix添加mysql監控：

1、建立hosts、關聯mysql模闆

雖然zabbix有mysql的監控模闆，但是也需要在mysql伺服器上準備擷取mysql status的腳本chk_mysql.sh，zabbix通過調用這個腳本來擷取mysql的運作資訊。

2、配置zabbix_agent

vim /etc/zabbix/zabbix_agentd.conf

    UserParameter=mysql.version,mysql -V

    UserParameter=mysql.status[*],/usr/local/zabbix/scripts/chk_mysql.sh $1

    UserParameter=mysql.ping,mysqladmin -uzabbix -p123456 -P3306 -h127.0.0.1  ping | grep -c alive   

3、資料庫添加賬号：

mysql -uroot -p

    GRANT PROCESS,SUPER,REPLICATION CLIENT ON *.* TO zabbix@'127.0.0.1' IDENTIFIED BY '123456';

4、寫check腳本

mkdir -p /usr/local/zabbix/scripts

vim /usr/local/zabbix/scripts/chk_mysql

#!/bin/sh 

MYSQL_SOCK="/usr/local/mysql/mysql.sock" 

MYSQL_USER='zabbix'

MYSQL_PWD='123456'

MYSQL_HOST='127.0.0.1'

MYSQL_PORT='3306'

ARGS=1 

if [ $# -ne "$ARGS" ];then 

    echo "Please input one arguement:" 

fi 

case $1 in 

    Uptime) 

        result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK status|cut -f2 -d":"|cut -f1 -d"T"` 

            echo $result 

            ;; 

        Com_update) 

            result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_update"|cut -d"|" -f3` 

        Slow_queries) 

        result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK status |cut -f5 -d":"|cut -f1 -d"O"` 

                echo $result 

                ;; 

    Com_select) 

        result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_select"|cut -d"|" -f3` 

    Com_rollback) 

        result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_rollback"|cut -d"|" -f3` 

    Questions) 

        result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK status|cut -f4 -d":"|cut -f1 -d"S"` 

    Com_insert) 

        result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_insert"|cut -d"|" -f3` 

    Com_delete) 

        result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_delete"|cut -d"|" -f3` 

    Com_commit) 

        result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_commit"|cut -d"|" -f3` 

    Bytes_sent) 

        result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Bytes_sent" |cut -d"|" -f3` 

    Bytes_received) 

        result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Bytes_received" |cut -d"|" -f3` 

    Com_begin) 

        result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_begin"|cut -d"|" -f3` 

        *) 

        echo "Usage:$0(Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions)" 

        ;; 

esac

别忘了腳本授權：

chmod u+x /usr/local/zabbix/chk_mysql.sh

chown -R zabbix.zabbix /usr/local/zabbix/chk_mysql.sh

腳本準備完後，重新開機agent

5、驗證

在zabbix-server伺服器上測試是否可以擷取到mysql的status資訊：

    zabbix_get -s 127.0.0.1 -p10050 -k mysql.status[Com_update] 

有結果就是ok的！

PS：zabbix_get指令：

zabbix_get -s 10.8.95.74 -p10050 -k "system.cpu.load[all,avg15]";

6、圖示

zabbix自帶模版預設有2個性能圖，這些圖要等運作一段時間後才能畫出來
