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 zabbix@'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: kbsonlong@gamil.com # 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: kbsonlong@gamil.com # 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
