Parameters
System Health: Average health value of all hosts in CVM. This parameter is displayed only in full screen mode.
Host Health: CVK host health statistics, including the CPU, memory, storage, network, and host health values of hosts.
The CPU, memory, or storage health value is calculated as follows:
When the CPU, memory, or storage usage is greater than 80%, in the range of 60% to 80%, and smaller than 60%, the CPU, memory, or storage health value is in the range of 0 to 50, 51 to 80, and 81 to 100, respectively.
The network health value is calculated as follows:
When the network throughput is greater than 1024 Mbps, in the range of 500 to 1024 Mbps, and smaller than 500 Mbps, the network health value is in the range of 0 to 50, 51 to 80, and 81 to 100, respectively.
The host health value is calculated as follows:
Host health=CPU health × 0.3 + memory health × 0.4 + storage health × 0.15 + network health × 0.15
Host Statistics: Total number of hosts and number of hosts in each state (including normal, abnormal, and maintain).
VM Statistics: Total number of VMs and number of VMs in each state (including normal, shutdown, and abnormal).
CPU Overcommit
Host: Total number of CPU cores on all hosts.
VM: Total number of CPUs that have been allocated to VMs.
CPU Overcommit: Host CPU usage, which is the ratio between the VM CPUs and the host CPUs.
Memory Overcommit
Host: Total memory size of all hosts.
VM: Total memory size of all VMs.
Memory Overcommit: Host memory usage, which is the ratio between the VM memory and the host memory.
Shared Storage Overcommit
Total: Total shared storage size.
Available: Available shared storage size.
Shared Storage Overcommit: Shared storage usage, which is the ratio between the used storage and the total storage.
Top 5 Clusters by I/O Through and IOPS: Statistics about the five clusters with the highest I/O throughput and IOPS values in the last 20 minutes. Hover over the curve chart to view the values.
System Alarms: Number of alarms for each alarm level.
Critical/Major System Alarms: Detailed information about the critical and major alarms. You can click More to enter the Alarms page, or click To deal with for an alarm to view alarm details.
Top 5 Hosts by CPU Usage: Statistics about the five hosts with the highest CPU usage values.
Top 5 Hosts by Memory Usage: Statistics about the five hosts with the highest memory usage values. Hover over the radar chart to view the memory usage values of the hosts.
Top 5 VMs by CPU Usage: Statistics about the five VMs with the highest CPU usage values.
Top 5 VMs by Memory Usage: Statistics about the five VMs with the highest memory usage values. Hover over the radar chart to view the memory usage values of the VMs.
Top 5 VMs by Disk Requests: Statistics about the five VMs with the highest number of disk access requests.
Top 5 VMs by Network Throughput: Statistics about the five VMs with the highest network throughput values. Hover over the radar chart to view the throughput values of the VMs.
Top 5 VMs by IOPS: IOPS trends of the five VMs with the highest IOPS values. This parameter is displayed only in full screen mode.
