2、主机列表文件如下所示，需以|分割提供服务器IP地址、用户名、密码、ssh端口、空格分开的多个需要监控的分区挂载点：
|
1 2 3 4 |
[root@imzcy ~]# cat imzcy/host.txt 192.168.2.4|zcy|123_pass|2222|"/ /u01/app/oracle/oradata" 192.168.2.5|zcy|123456|22|"/ /data" [root@imzcy ~]# |
3、执行效果如下：
|
1 2 3 4 5 6 7 8 9 10 |
[root@imzcy ~]# sh imzcy/index.sh 192.168.2.4: / 总共: 36G 可用: 1.5G 使用率: 96% /u01/app/oracle/oradata 总共: 394G 可用: 12G 使用率: 97% 192.168.2.5: / 总共: 509G 可用: 210G 使用率: 57% /data 总共: 509G 可用: 3.0G 使用率: 100% [root@imzcy ~]# |
