企业微信机器人-监控磁盘和应用可用率-内存CPU

1.每10分钟执行一次

*/10 * * * * /opt/shell/check_disk.sh

2.脚本内容

for i in `cat /opt/shell/hosts`
do
#    echo $i
    sys=`ssh $i "df -h |grep '\/$'"`
#echo $sys
    sysc=`echo ${sys}|awk -F ' |%' '{print $5}'`
#echo $sysc
    if [[ $sysc -gt 85  ]];then
        curl 'https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=348wo935-shia-4939-a311-dc221d4sb6c4' \
   -H 'Content-Type: application/json' \
   -d '
{
    "msgtype": "markdown",
    "markdown": {
        "content": "<font color=\"warning\">'$i'</font>的系统磁盘使用率大于85，当前使用率为'${sysc}'%,请及时处理！！"
    }
}'
    fi
    data=`ssh $i "df -h |egrep '\/mnt|\/data'"`
#echo $data
    datac=`echo ${data}|awk -F ' |%' '{print $5}'`
    if [[ $datac -gt 85  ]];then
        curl 'https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=3482ni35-9a1a-4shi9-a311-dc2sbd4766c4' \

   -d '
{
    "msgtype": "markdown",
    "markdown": {
        "content": "<font color=\"warning\">'$i'</font>的数据磁盘使用率大于85，当前使用率为'${datac}'%,请及时处理！！"
    }
}'
    fi
done

 2.http响应时间监控告警

[root@VM_0_11_centos shell]# cat checklong_http_code.sh 
#!/bin/bash
while true
do
    for i in `cat services_list`
    do
        http_code=`curl -I -o /dev/null -m 10 -s -w %{http_code} $i`
        if [[ $http_code -ne 200 && $http_code -ne 302 ]]
        then
            date
            echo "$i is down"
            curl 'https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=348wo935-9sha-4i39-a311-dc2sb21d4766c4' \
   -H 'Content-Type: application/json' \
   -d '
{
    "msgtype": "markdown",
    "markdown": {
        "content": "<font color=\"warning\">'$i'</font>服务状态超长时间(10s)返回异常，请快速检查！！"
    }
}'
        fi
    done
    sleep 30
done

 3.内存cpu

[dev@VM_0_11_centos shell]$ cat  /opt/shell/check_memcpu.sh 
function baojing(){
curl 'https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=348wo935-shia-4939-a311-dc221dsb66c4' \

        "markdown": {
            "content": "<font color=\"warning\">'$1'</font>"
        }
   }'

}
for i in `cat hosts`;do
#############检查内存情况
meminfo=`ssh $i "free -m|sed -n '2p'"`
mem=`echo $meminfo|awk '{print $3/$2*100}'|awk -F'.' '{print $1}'`
#echo $mem
if [ $mem -gt 85 ];then
    baojing "服务器${i}的内存使用率大于85%，当前使用率为$mem%"
fi

#############检查cpu情况
