自定义监控(阿里云&zabbix)
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: http://help.aliyun.com/knowledge_detail.htm?knowledgeId=5974901
使用shell版本做演示
监控mysql主从状态:
1.创建自定义监控项
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/bin
export 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/null0
if [ $? -eq 0 ];then
Slave_IO=`mysql -u${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" ] && [ "$Slave_SQL" == "Yes" ];then
STAT=1 && echo "$data mysql-status is ok">>/var/log/mysql-status.log
else
STAT=0 && echo "$data mysql-status is error">>/var/log/mysql-status.log
fi
else
STAT=0 && echo "$data mysql-status is error">>/var/log/mysql-status.log
fi
/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
#!/bin/bash
#########################################
#Usage: sh cms_post.sh
#Author: CMS Dev Team
#Company: Aliyun Inc.
#Version: 1.0

#parameters instructions
# $1: ali_uid, $2: metric_name, $3: metric_value, $4:fields
#convert current time to milliseconds
if [[ ! "$#" -eq 4 ]];then
echo "usage: $0 userId, metricName, value, dimensions"
echo "--multiple dimensions like 'ip=111.111.111.111,hostname=cms'"
exit 1
fi
#biz time
timestamp=`date +%s%N | cut -b1-13`
#build dimensions json
arr=(${4//,/ })
dimensions="{"
for i in "${arr[@]}"; do
kv=(${i//=/ })
dimensions=${dimensions}'"'${kv[0]}'":"'${kv[1]}'",'
done
dimensions=${dimensions%,*}
dimensions=${dimensions}'}'
#build namespace and metrics
userId="$1"
namespace="acs/custom/$1"
metrics='[{"metricName":"'"$2"'","value":'"$3"',"unit":"None","timestamp":'"$timestamp"',"dimensions":'"$dimensions"'}]'
url="http://openNaNs.aliyun.com/metrics/put"
params="userId=$userId&namespace=$namespace&metrics=$metrics"
echo "params: ${params}"
curl -v ${url} --data ${params}添加完成监控后,监控图表如下:
告警配置
Status填写变量HOSTNAME 统计周期填写告警触发间隔
二、Zabbix监控方式
在被监控服务器上需要先安装zabbix-sender 来给zabbix-server提交发送数据
rpm -ivh http://repo.zabbix.com/zabbix/3.0/rhel/6/x86_64/zabbix-release-3.0-1.el6.noarch.rpm
yum install zabbix-sender -y#!/bin/bash
mysql_user='root'
mysql_pass='123.com'
mail="xuel@51idc.com"
data=$(date +%Y-%m-%d-%H:%M)
netstat -lntup|egrep ":3306"|grep -v grep>/dev/null0
if [ $? -eq 0 ];then
Slave_IO=`mysql -u${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" ] && [ "$Slave_SQL" == "Yes" ];then
STAT=1 && echo "$data mysql-status is ok">>/var/log/mysql-status.log
else
STAT=0 && echo "$data mysql-status is error">>/var/log/mysql-status.log
fi
else
STAT=0 && echo "$data mysql-status is error">>/var/log/mysql-status.log
fi
zabbix_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
监控项目
触发器
