自定义监控（阿里云&zabbix）-白红宇

目前阿里云对25端口有限制，无法在阿里云上搭建邮件服务器发送告警邮件，如果需要邮件通知，可以采取下面方法：

1.开同阿里云企业邮箱

2.使用阿里云监控告警

3.第三方开源监控系统zabbix自定义脚本监控

一、阿里云自定义监控

阿里云提供自定义监控SDK，这有助于我们定制化的根据自身业务来做监控，下面我就根据业务需求来介绍一个简单的自定义监控配置。

阿里提供了2个版本的自定义监控接口：

自定义监控SDK（python版）：cms_post.py

自定义监控SDK（bash版）：cms_post.sh

下载地址：

使用shell版本做演示

监控mysql主从状态：

1.创建自定义监控项

3eeeca1214b9fdb8ff208ba6c3f82c42a461a0cf

脚本post

方法说明

1.命名空间中的字符串，用户aliuid

2.监控项名称，用户创建监控项时填写的名称

3.监控项值，用户上报到云监控的业务数据

4.字段信息，结合监控项，表示具体业务字段意义。

mysql主从监控脚本

cat mysql_check.sh

#!/bin/bash export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/binexport HOSTS=$(hostname)mysql_user='root'mysql_pass='123.com'mail="xuel@51idc.com"data=$(date +%Y-%m-%d-%H:%M)netstat -lntup|egrep ":3306"|grep -v grep>/dev/null0if [ $? -eq 0 ];thenSlave_IO=`mysql -u${mysql_user} -p${mysql_pass} -e "show slave status\G"|grep "Slave_IO_Running:"|awk -F": " '{print $2}'`Slave_SQL=`mysql -u${mysql_user} -p${mysql_pass} -e "show slave status\G"|grep "Slave_SQL_Running:"|awk -F": " '{print $2}'`if [ "$Slave_IO" == "Yes" ] && [ "$Slave_SQL" == "Yes" ];thenSTAT=1 && echo "$data mysql-status is ok">>/var/log/mysql-status.logelseSTAT=0 && echo "$data mysql-status is error">>/var/log/mysql-status.logfielseSTAT=0 && echo "$data mysql-status is error">>/var/log/mysql-status.logfi/scripts/cms_post.sh 1931875513165389 mysql_status $STAT status=$HOSTS

制作定时任务，没分钟调用check脚本来上数据

cms_post.sh 阿里云上报脚本

二、Zabbix监控方式

在被监控服务器上需要先安装zabbix-sender 来给zabbix-server提交发送数据

rpm -ivh http://repo.zabbix.com/zabbix/3.0/rhel/6/x86_64/zabbix-release-3.0-1.el6.noarch.rpmyum install zabbix-sender -y#!/bin/bashmysql_user='root'mysql_pass='123.com'mail="xuel@51idc.com"data=$(date +%Y-%m-%d-%H:%M)netstat -lntup|egrep ":3306"|grep -v grep>/dev/null0if [ $? -eq 0 ];thenSlave_IO=`mysql -u${mysql_user} -p${mysql_pass} -e "show slave status\G"|grep "Slave_IO_Running:"|awk -F": " '{print $2}'`Slave_SQL=`mysql -u${mysql_user} -p${mysql_pass} -e "show slave status\G"|grep "Slave_SQL_Running:"|awk -F": " '{print $2}'`if [ "$Slave_IO" == "Yes" ] && [ "$Slave_SQL" == "Yes" ];thenSTAT=1 && echo "$data mysql-status is ok">>/var/log/mysql-status.logelseSTAT=0 && echo "$data mysql-status is error">>/var/log/mysql-status.logfielseSTAT=0 && echo "$data mysql-status is error">>/var/log/mysql-status.logfizabbix_sender -z 192.168.1.234 -s "test-mysql-status" -k mysql -o $STAT

-z zabbix-server的地址

-s 监控项目名称

-k 键值
