You can view your disk usages in either of the following ways:
- View disk usages manually.
The details depend on the OS. This FAQ uses Windows Server 2008, Windows Server 2016, and Linux as samples to describe how to view the disk usage.

Viewing Disk Usage in Linux
In this section, CentOS 7.4 64bit is used as an example. The details depend on if you need to view the available space or not.
- To query the total capacity only, run lsblk.Information similar to the following is displayed:
[root@ecs-test-0001 ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT vda 253:0 0 40G 0 disk └─vda1 253:1 0 40G 0 part / vdb 253:16 0 40G 0 disk └─vdb1 253:17 0 40G 0 part
In the command output, the server has two disks, /dev/vda and /dev/vdb. System disk /dev/vda has 40 GB of capacity, as does data disk /dev/vdb.
- To query the total capacity and display the space available as well, run df -TH. Ensure that the disk has been attached and initialized before running this command.
Information similar to the following is displayed:
[root@ecs-0001 ~]# df -TH Filesystem Type Size Used Avail Use% Mounted on /dev/vda1 ext4 43G 2.0G 39G 5% / devtmpfs devtmpfs 509M 0 509M 0% /dev tmpfs tmpfs 520M 0 520M 0% /dev/shm tmpfs tmpfs 520M 7.2M 513M 2% /run tmpfs tmpfs 520M 0 520M 0% /sys/fs/cgroup tmpfs tmpfs 104M 0 104M 0% /run/user/0 /dev/vdb1 ext4 43G 51M 40G 1% /mnt/sdc
In the command output, the server has two partitions, /dev/vda1 and /dev/vdb1. Partition /dev/vda1 is used to deploy the OS, and its total capacity, used capacity, and available capacity are 43 GB, 2 GB, and 39 GB, respectively. Partition /dev/vdb1's total capacity, used capacity, and available capacity are 43 GB, 51 MB, and 40 GB, respectively.

Installing Agent to View Disk Usage
Some disk monitoring metrics require that the agent to be installed.
- For instructions about how to install the agent on a Windows ECS, see "Installing and Configuring the Agent (Windows)" in the Cloud Eye User Guide.
- For instructions about how to install the agent on a Linux ECS, see "Installing and Configuring the Agent (Linux)" in the Cloud Eye User Guide.
