ZStack Cloud monitor can switch between different hypervisors or zones. You can select and change the hypervisor or zone through the drop-down box in the upper right corner to display different monitoring results.

• Supports the change between the KVM hypervisor and the vCenter hypervisor.
• Allows to monitor on all zones or a specific zone.
• The differences between the KVM hypervisor and the vCenter hypervisor are as follows:
  • The major resource overview of the vCenter hypervisor does not include cluster information.
  • The usage statistics of the vCenter hypervisor does not display the IPv6 networks.

The monitor collects usage statistics on the CPU and memory of VM instances/hosts in the selected hypervisor and zone, and displays the top 5 of VM instances or hosts in real time based on VM CPU utilization, VM memory utilization, host CPU utilization, and host memory utilization. The top rankings are displayed in real time and indicated by blue, yellow, and red progress bars, so that you can easily know what resources are running out at the moment.

The monitor collects usage statistics on the CPU, memory, disk, and network resource of all hosts of the data center in the selected hypervisor and zone, and provides real-time monitoring on the CPU utilization of all hosts, memory utilization of all hosts, host disk I/O sum, and host network throughput sum respectively. The monitoring results are displayed in the form of dynamic graphs in real time, and monitoring items are differentiated by colors, which can visually present you the resource utilization and performance status of all current hosts.

The monitor collects usage statistics on relevant physical resources of the data center in the selected hypervisor and zone, and provides real-time monitoring on the usage of CPU, memory, primary storage, image storage, private IP, public IP, GPU, vGPU, and others. The resource usages are displayed in real time and indicated by blue, yellow and red progress bars, so that you can easily know the resource utilization at the moment.

• The private IP and public IP of KVM hypervisor support the display of IPv4 and IPv6 resources respectively. You can click the small arrow below to switch.
• If GPU and vGPU are not attached to the Cloud, the usage statistics does not display the utilization of GPU and vGPU.
• The resource usage is displayed by progress bars in different colors. If the resource utilization is less than 60%, the progress bar is shown in blue. If the resource utilization is between 60% (inclusive) and 80%, the progress bars is shown in yellow. If the resource utilization is between 80% and 100% (both inclusive), the progress bars is shown in red.

The monitor collects usage statistics on the VM instances, hosts, images, and clusters of the data center in the selected hypervisor and zone, and provides real-time monitoring on their total utilization.

• The differences between the KVM hypervisor and the vCenter hypervisor are as follows:
  • The vCenter hypervisor does not display the VM instance tag.
  • The usage statistics of the vCenter hypervisor does not display the IPv6 networks.

The monitor collects usage statistics on the CPU, memory, disk, and network resource of all hosts of the data center in the selected hypervisor and zone, and provides real-time monitoring on the CPU utilization of all hosts, memory utilization of all hosts, host disk I/O sum, and host network throughput sum respectively.

The monitoring results are displayed in the form of dynamic graphs in real time, and monitoring items are differentiated by colors, which present you the resource utilization and performance status of all current hosts.

The load trend supports dynamic switching, which means the statistics graphs of all hosts are switched every 15 seconds, and you can also click and switch the graphs manually.

The monitor collects usage statistics on relevant physical resources of the data center in the selected hypervisor and zone, and provides real-time monitoring on the usage of CPU, memory, primary storage, image storage, private IP, public IP, GPU, vGPU, and others. The resource usages are displayed in real time and indicated by blue, yellow and red progress bars, so that you can easily know the resource utilization at the moment.

• The monitor pushes usage statistics every 21 seconds. After each push, the increase or decrease of usage can be indicated by the red arrow or blue arrow in the lower right corner respectively.
• The private IP and public IP support the display switching between IPv4 and IPv6 network addresses. By default, the change occurs every 15 seconds, and you can also click and switch it manually. In case there is only one type of network address, the usage statistics will only show the existing network type by default, and the automatic switching will not be supported.
• If GPU and vGPU are not attached to the Cloud, the usage statistics does not display the utilization of GPU and vGPU.
• The resource usage is displayed by progress bars in different colors. The resource utilization less than 60% is indicated by the color blue. The resource utilization equal to or more than 60% but less than 80% is indicated by the color yellow. The resource utilization equal to or more than 80% but less than or equal to 100% is indicated by the color red.

The monitor collects usage statistics on the VM instances, hosts, images, and clusters of the data center in the selected hypervisor and zone, and provides real-time monitoring on their total utilization.

The load statistics supports dynamic switching, which means the statistics graphs are switched every 15 seconds, and you can also click and switch the graphs manually.

The monitor collects alarm messages set in ZStack Cloud and pushes the latest five alarm messages to the monitor display, which can intuitively inform you of the current risks in the Cloud.

The monitor collects statistics of personnel in the account system or tenant management (Tenant Management License needs to be added) of ZStack Cloud. The account overview is displayed in real time.

• The account overview displays the accounts (including admin accounts) and the number of tenants in ZStack Cloud if the Tenant Management License is not added.
• The account overview displays the number of platform managers in tenant management and number of tenants in ZStack Cloud if the Tenant Management License is added.
• The account overview supports the whole platform, and the switching between hypervisors or zones does not affect the statistical results.

The monitor collects statistics on the KVM VM instance tags as well as the tags bound to KVM VM instances in the selected hypervisor and zone, and provides the tags cloud in different colors and sizes. When more VM instances are bound to a tag, this tag will be more eye-catching with larger size and brighter color, which can intuitively inform you which VM tags are more popular.

The monitor collects usage statistics on the CPU and memory of VM instances/hosts in the selected hypervisor and zone, and displays the top 5 of VM instances or hosts in real time based on VM CPU utilization, VM memory utilization, host CPU utilization, and host memory utilization.
