Dedicated Host:View and export the information of a dedicated host

View the information of a dedicated host

On the Host Details tab, you can view the information of a dedicated host, including the ID, name, billing method, machine ID, and the number of physical CPU cores.

1. Log on to the ECS console.

2. In the left-side navigation pane, choose Instances & Images > > Dedicated Hosts.

3. In the top navigation bar, select the region and resource group to which the resource belongs.

4. On the Dedicated Hosts page, click the Host tab.

5. Find the dedicated host that you want to view and click Details in the Actions column.

6. In the panel that appears, view the information of the dedicated host.

   • To view the ECS instances that run on the dedicated host, click the Instances tab.

   • To view the properties of the dedicated host, click the Host Details tab.

     The properties of a dedicated host include whether automatic deployment and failover are enabled, vCPU usage, memory usage, and the number of sockets, as shown in the following figure.

     Note

     Before you create an ECS instance on a dedicated host, we recommend that you check the available computing resources (vCPUs and memory) to determine whether the ECS instance can be created. For more information, see Why do I fail to create an ECS instance on a dedicated host even though there are sufficient available resources on the dedicated host?

     

Export the information of a dedicated host

You can export the information of all dedicated hosts, such as the host type, vCPU usage, and memory usage, in a region for backup or save the information as a report.

1. Log on to the ECS console.

2. In the left-side navigation pane, choose Instances & Images > > Dedicated Hosts.

3. In the top navigation bar, select the region and resource group to which the resource belongs.

4. On the Host tab, click .

   The exported data is saved in a CSV file, such as ecs_dedicatedHost_list_cn-hangzhou_2020-07-29.csv.

FAQ

Why do I fail to create an ECS instance on a dedicated host even though there are sufficient available resources on the dedicated host?

Typically, each dedicated host has two CPUs, labeled as Socket 0 and Socket 1. To maximize the performance of an ECS instance on a dedicated host, the ECS instance is created on a single socket.

• If the available computing resources on one socket meet or exceed the requirements of the ECS instance that you want to create, the ECS instance can be created.

• If the available computing resources on each socket are insufficient to meet the requirements, the ECS instance cannot be created, even if the combined available resources of both sockets are sufficient.

The following figure shows an example:

The following table lists the dedicated host types with socket information available and the number of sockets each type supports.
