Zabbix监控Mysql多实例自动添加

1、定义每个实例的端口

cat mysql_port
3306
3307
3308
3309
3310
 3311
3312
3313

2、给所有实例创建一个zabbix用户只允许本地访问，生产环境具体权限各位看官自己看着给吧O(∩_∩)O

GRANT ALL PRIVILEGES ON *.* TO [email protected]‘127.0.0.1‘ IDENTIFIED BY ‘zabbix‘;

3、创建自动发现MySQL端口脚本

cat /data/PRG/zabbix/scripts/discovery_mysql.sh

#!/bin/bash
# -------------------------------------------------------------------------------
# Script_name: discovery_mysql.sh
# Revision:    1.0
# Date:        2017/03/09
# Author:      kbsonlong
# Email:       [email protected]
# Website:     www.along.party
# -------------------------------------------------------------------------------

res=`cat /data/PRG/zabbix/scripts/mysql_port|grep -v "^#"`
port=($res)
printf ‘{\n‘
printf ‘\t"data":[\n‘
for key in ${!port[@]}
do
    if [[ "${#port[@]}" -gt 1 && "${key}" -ne "$((${#port[@]}-1))" ]];then
        printf ‘\t {\n‘
        printf "\t\t\t\"{#MYSQLPORT}\":\"${port[${key}]}\"},\n"
    else [[ "${key}" -eq "((${#port[@]}-1))" ]]
        printf ‘\t {\n‘
        printf "\t\t\t\"{#MYSQLPORT}\":\"${port[${key}]}\"}\n"
    fi
done
printf ‘\t ]\n‘
printf ‘}\n‘

4、创建MySQL检测脚本

# cat /data/PRG/zabbix/scripts/check_Multimysql.sh
#!/bin/bash
# -------------------------------------------------------------------------------
# FileName:    check_Multimysql.sh
# Revision:    1.0
# Date:        2017/03/09
# Author:      kbsonlong
# Email:       [email protected]
# Website:     www.along.party
# License:     GPL
# -------------------------------------------------------------------------------

# 用户名
MYSQL_USER=‘zabbix‘

# 密码
MYSQL_PWD=‘zabbix‘

# 主机地址/IP
MYSQL_HOST=‘127.0.0.1‘

# 端口
MYSQL_PORT=$2

# 数据连接
MYSQL_CONN="/usr/bin/mysqladmin -u${MYSQL_USER} -p${MYSQL_PWD} -h${MYSQL_HOST} -P${MYSQL_PORT}"

##help函数
help() {
        echo "Usage:$0  [ping|Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions|Com_insert|Com_delete|Com_commit|Bytes_sent|Bytes_received|Com_begin]  port"
}

# 参数是否正确
if [ $# -lt "2" ];then
    echo "参数缺失!"
    help
    exit 2
fi 

# 获取数据
case $1 in
    ping)
        result=`${MYSQL_CONN} ping | grep -c alive`
        echo $result
        ;;
    Uptime)
        result=`${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 $result
                ;;
    Com_begin)
        result=`${MYSQL_CONN} extended-status |grep -w "Com_begin"|cut -d"|" -f3`
                echo $result
                ;; 

        *)
        help
        ;;
esac

5、测试脚本是否正常

# bash discovery_mysql.sh
{
        "data":[
         {
                        "{#MYSQLPORT}":"3306"},
         {
                        "{#MYSQLPORT}":"3307"},
         {
                        "{#MYSQLPORT}":"3308"},
         {
                        "{#MYSQLPORT}":"3309"},
         {
                        "{#MYSQLPORT}":"3310"},
         {
                        "{#MYSQLPORT}":"3311"},
         {
                        "{#MYSQLPORT}":"3312"},
         {
                        "{#MYSQLPORT}":"3313"}
         ]
}

# bash check_Multimysql.sh
参数缺失!
Usage:check_Multimysql.sh  [ping|Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions|Com_insert|Com_delete|Com_commit|Bytes_sent|Bytes_received|Com_begin]  port
# bash check_Multimysql.sh ping 3306
1
# bash check_Multimysql.sh Uptime 3306
18180446

6、zabbix agent配置文件添加自定义脚本，并重启zabbix agent

vim /data/PRG/zabbix/etc/zabbix_agentd.conf

UserParameter=mysql_discovery[*],/bin/bash /data/PRG/zabbix/scripts/discovery_mysql.sh
#####$1==command   $2===port
UserParameter=mysql.status[*],/data/PRG/zabbix/scripts/check_mysql.sh $1 $2
UserParameter=mysql.ping[*],/data/PRG/zabbix/scripts/check_mysql.sh ping $1

/etc/init.d/zabbix_agentd restart

7、使用zabbix_get检查定义的key是否生效

# /usr/local/zabbix/bin/zabbix_get -s 192.168.62.200 -k mysql.ping[3307]
1
# /usr/local/zabbix/bin/zabbix_get -s 192.168.62.200 -k mysql.status[Uptime,3307]
18180813
# /usr/local/zabbix/bin/zabbix_get -s 192.168.62.200 -k mysql.status[Uptime,3306]
18180842
# /usr/local/zabbix/bin/zabbix_get -s 192.168.62.200 -k mysql.status[Uptime,3310]
18180847
# /usr/local/zabbix/bin/zabbix_get -s 192.168.62.200 -k mysql.status[Bytes_sent,3310]
58803854473

8、导入模板Template Multi Mysql.xml

9、被监控主机关联模板

自动发现规则mysql_discovery

自动添加的监控项

最新监控数据
