- 写一个配置文件保存被监控主机SSH连接信息,格式:IP User Port
[root@Test ~]# cat host
10.10.10.10 root 22
10.10.10.11 root 22
- 配置防火墙规则
iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
- 创建ssh免密通道
[root@Test ~]# ssh-keygen -t rsa -f ~/.ssh/id_dsa -P ""
[root@Test ~]# ssh-copy-id root@10.10.10.10
[root@Test ~]# ssh-copy-id root@10.10.10.11
- 脚本如下
#!/bin/bash
disk_file=/tmp/disk
host_info=host
function info() {
echo -e " 33[32m [INFO] 33[0m$@ "
}
function warn() {
echo -e " 33[31m [WARN] 33[0m$@"
}
for IP in `cat $host_info |awk '/^[^#]/{print $1}'`; do
user=`awk -v ip=$IP '$1==ip{print $2}' $host_info`
port=`awk -v ip=$IP '$1==ip{print $3}' $host_info`
ssh -p $port $user@$IP df -h > $disk_file
USE_RATE_LIST=`cat $disk_file |awk 'BEGIN{OFS="="}/^/dev/{print $1,int($5)}'`
log_info "------------------------------------------------------"
for USE_RATE in $USE_RATE_LIST; do
PART_NAME=${USE_RATE%=*}
USE_RATE=${USE_RATE#*=}
if [ $USE_RATE -ge 10 ]; then
warn " $IP $PART_NAME $USE_RATE%!"
else
info " $IP $PART_NAME $USE_RATE%!"
fi
done
done
