View the details of a node

This topic describes how to view the details of a node in the KubeSphere Virtualization (KSV) web console.

Prerequisites

The user that you use has been granted the permissions to use the Physical Resources module. The Physical Resources module is available only to user admin.

Procedure

1. Log in to the KSV web console.

2. In the top navigation bar, click Physical Resources to go to the management page of physical resources.

3. In the left-side navigation pane, choose Nodes > Physical Nodes.

4. On the Nodes page, click the name of the node that you want to view. The details page of the node appears.

5. On the left side of the details page, view basic information and physical resource statistics about the node.

   Parameter	Description
   Status	The health status of the node.
   IP	The IP address of the node. Nodes in the same cluster can communicate with each other using IP addresses.
   Role	The role of the node in the cluster. KSV provides workers nodes and control nodes. In single-node mode, the node serves as the control node and the worker node. In multi-node mode, the node role is specified when you install KSV or add a node. A node can run as a control node or a worker node, or a control and worker node at the same time. You can create VMs on worker nodes.
   OS	The OS type of the node. The server node on which KSV is installed must run on Linux, and the kernel version of Linux must be 4.0 or later. We recommend that you use one of the following OSs: Ubuntu 18.04, Ubuntu 20.04, CentOS 7.9, Unity Operating System (UOS), Kylin V10, and EulerOS.
   Kernel	The kernel version of the OS used by the node.
   Architecture	The architecture used by the node.
   Created at	The time when the node was added.
   CPU Model	The CPU model used by the node.
   CPU cores	The number of physical CPU cores provided by the node. The following formula can be used: Total number of CPU cores = Number of physical CPUs x Number of CPU cores per physical CPU.
   Physical Disks	The number of physical disks inserted on the node.
   Physical NICs	The number of physical NICs inserted on the node.

6. On the right side of the details page, click Overview to view the resource overview of the node.

   Section	Description
   Usage	The resource usage of the node, including the CPU, memory, data disk, and system disk resources.
   Requests and Limits	The resource limits and requests of the node, including the CPU and memory resources.
   Monitoring	The monitoring of cluster resources, including compute, network, and storage resources. You can expand the drop-down list next to Monitoring to specify a time range to query. KSV allows you to view resource statistics in the latest 7 days.
   Compute	The monitoring of compute resources, including the CPU usage, average CPU workloads, and memory usage.
   Networks	The monitoring of network resources, including the inbound and outbound traffic and packet loss rate. You can expand the drop-down list next to Networks to specify an NIC to view its network performance.
   Storage	The monitoring of storage resources, including the disk usage, throughput, IOPS, average I/O latency, and I/O queue length. You can expand the drop-down list next to Storage to specify a physical disk to view its resource usage.

7. On the right side of the details page, click VMs to view the VMs that run on the node.

   Parameter	Description
   Name	The custom name of the VM. The name can contain only lowercase letters, digits, and hyphens (-), and must start and end with a lowercase letter or a digit. The name can contain up to 16 characters in length. If you create multiple VMs at a time, the system automatically appends a sequential number to the name of each VM.
   Status	The status of the VM.
   OS	The OS type of the VM. You can place the cursor on the OS to view the specific type and version of the OS.
   IP Address	The IP address of the VM. If a VM contains multiple NICs, multiple IP addresses are assigned to the VM.
   CPU Usage	The CPU usage of the VM.
   Memory Usage	The memory usage of the VM.
   System Disk	The system disk size of the VM.

8. On the right side of the details page, click Disks to view the physical disks inserted on the node.

   Parameter	Description
   Name	The custom name of the disk. The name can contain only lowercase letters, digits, and hyphens (-), and must start and end with a lowercase letter or a digit. The name can contain up to 16 characters in length. If you create multiple disks at a time, the system automatically appends a serial number to the name of each disk.
   Type	The type of the disk. KSV provides system disks and data disks.
   Model	The model of the disk. KSV supports SATA disks, HDDs, and SSDs.
   Size	Th size of the disk.
   Mount Target	The mount point of the disk, which is the entry point of the filesystem.
   Filesystem	The filesystem of the disk.

9. On the right side of the details page, click Physical NICs to view the physical NICs inserted on the node.

   Parameter	Description
   Name	The name of the NIC.
   MAC Address	The physical address of the NIC, which is the unique identifier of the NIC in the network.
   Status	The status of the NIC.
   Type	The type of the NIC. KSV supports physical NICs and virtual NICs.
   IP Address	The IP address of the NIC.
   MTU	The maximum transmission unit (MTU) of the NIC.
   Max. Rate	The maximum transmission rate of the NIC.
   Current Rate	The current transmission rate of the NIC.

10. On the right side of the details page, click Alerts to view the alerts generated on the node.

    Parameter	Description
    Alert Message	The alert message that is automatically generated after the alert is fired.
    Status	The status of the alert. Valid values: Firing: The alert trigger condition has been met for a period of time specified in the alert rule. Pending: The alert trigger condition has not been met for a period of time specified in the alert rule. Normal: The alert trigger condition has not been met.
    Severity	The severity of the alert. Valid values: Critical: an alert condition that requires immediate response. Major: an error without the need to take immediate action. Minor: a non-critical condition that has not caused a degradation in performance.
    Alert Policy	The custom name of the alert policy. The name can contain only letters, digits, and hyphens (-), and must start and end with a letter or a digit. The name can be up to 16 characters in length.
    Fired at	The time when the alert was fired.

11. On the right side of the details page, click Events to view the events generated on the node.

    Parameter	Description
    Type	The type of the event.
    Cause	The reason why the event was generated.
    Occurred at	The time when the event happened.
    Source	The name of the resource on which the event happened.
    Message	The message that is automatically generated after the event happened.

12. (Optional) Click Export in the upper-right corner to export the events to your local environment.
