zabbix监控mysql_MySQL

2、编写脚本，获取mysql的各种状态值。可以固定一个目录，专门存放监控脚本。比如/usr/local/zabbix/scripts/chk_mysql.sh

#!/bin/bash

MYSQL_CONN="/alidata/mysql/bin/mysqladmin -u ${MYSQL_USER} -p${MYSQL_PWD} -h${MYSQL_HOST} -P${MYSQL_PORT}"

# 参数是否正确
if [ $# -ne "1" ];then 
    echo "arg error!"

# 获取数据
case $1 in

        result=`${MYSQL_CONN} status|cut -f2 -d":"|cut -f1 -d"T"` 
        echo $result 
        ;; 
    Com_update) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_update"|cut -d"|" -f3` 
        echo $result 
        ;; 
    Slow_queries) 
        result=`${MYSQL_CONN} status |cut -f5 -d":"|cut -f1 -d"O"` 
        echo $result 
        ;; 
    Com_select) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_select"|cut -d"|" -f3` 
        echo $result 
                ;; 
    Com_rollback) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_rollback"|cut -d"|" -f3` 
                echo $result 
                ;; 
    Questions) 
        result=`${MYSQL_CONN} status|cut -f4 -d":"|cut -f1 -d"S"` 
                echo $result 
                ;; 
    Com_insert) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_insert"|cut -d"|" -f3` 
                echo $result 
                ;; 
    Com_delete) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_delete"|cut -d"|" -f3` 
                echo $result 
                ;; 
    Com_commit) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_commit"|cut -d"|" -f3` 
                echo $result 
                ;; 
    Bytes_sent) 
        result=`${MYSQL_CONN} extended-status |grep -w "Bytes_sent" |cut -d"|" -f3` 
                echo $result

    Bytes_received) 
        result=`${MYSQL_CONN} extended-status |grep -w "Bytes_received" |cut -d"|" -f3` 
                echo $result

        result=`${MYSQL_CONN} extended-status |grep -w "Com_begin"|cut -d"|" -f3` 
                echo $result 
                ;; 
                        
        *) 
        echo "Usage:___FCKpd___0(Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions|Com_insert|Com_delete|Com_commit|Bytes_sent|Bytes_received|Com_begin)" 
        ;; 
esac

3、修改zabbix的配置文件/usr/local/zabbix-agentd/etc/zabbix_agentd.conf，添加

#获取mysql版本
UserParameter=mysql.version,mysql -V
##获取mysql性能指标,这个是上面定义好的脚本
UserParameter=mysql.status[*],bash /alidata/zabbix-agentd/scripts/chk_mysql.sh $1
##获取mysql运行状态
UserParameter=mysql.ping,/alidata/mysql/bin/mysqladmin -uroot -pliujinWANG1985 -P3306 -h127.0.0.1  ping | grep -c alive
UserParameter=mysql.process,/alidata/mysql/bin/mysql -uroot -pliujinWANG1985 -P3306 -h127.0.0.1  -e "show processlist" 2>/dev/null|wc -l

4、重启zabbix的客户端
