Performance TOP5 is a visual performance monitoring page. This page provides a direct and simple display of the top 5 monitoring metrics of various resources, such as VM instances, routers, hosts, L3 networks, and VIPs. With Performance TOP5, you can directly manage the real-time health state of resources on the Cloud, and improve the O&M efficiency.

• Host tab page:

  On the host tab page, the Cloud analyzes utilizations of CPUs, memories, disks, and network resources of all hosts under the current zone. In addition, the Cloud provides a real-time monitoring display of top 5 resources by taking average CPU utilization, memory utilization, disk read/write IPOS, used disk capacity in percent, disk read/write speed, NIC out/in speed, NIC out/in package rate, and NIC out/in error rate as performance metrics. Different colors of real-time percentage ranks and progress bars will directly indicate resource utilizations or performance bottlenecks, as shown in Host Performance TOP5.

• VM tab page:
  The VM instance page includes external monitoring and internal monitoring.

  • Similar to the host tab page, the external monitoring page provides a utilization analysis of CPUs, memories, disks, and network resources of all VM instances under the current zone. In addition, the external monitoring page provides a real-time monitoring display of top 5 resources by taking average CPU utilization, memory utilization, memory free (idle) in percent, disk read/write IPOS, disk read/write speed, NIC out/in speed, NIC out/in package rate, and NIC out/in error rate as performance metrics. Different colors of real-time percentage ranks and progress bars will directly indicate resource utilizations or performance bottlenecks.
  • To check the internal monitoring of VM instances, install an agent. On the internal monitoring page, the Cloud analyzes utilizations of CPUs, memories, and disks of all VM instances under the current zone. In addition, the Cloud provides a real-time monitoring display of top 5 resources by taking average CPU utilization, memory utilization, memory free in percent, used disk capacity in percent, and disk free in percent as performance metrics. Different colors of real-time percentage ranks and progress bars will directly indicate resource utilizations or performance bottlenecks, as shown in VM Internal Monitoring TOP5.

    
    
    

    Note: For memory data, internal monitoring is more accurate than external monitoring. We recommend that you use internal monitoring to monitor memory data.
• Router tab page:
  The router tab page includes external monitoring and internal monitoring.

  • Similar to the VM instance tab page, the external monitoring page provides a utilization analysis of CPUs, memories, disks, and network resources of all routers (including vRouters and VPC vRouters) under the current zone. In addition, the external monitoring page provides a real-time monitoring display of top 5 resources by taking average CPU utilization, memory utilization, memory free (idle) in percent, disk read/write IPOS, disk read/write speed, NIC out/in speed, NIC out/in package rate, and NIC out/in error rate as performance metrics. Different colors of real-time percentage ranks and progress bars will directly indicate resource utilizations or performance bottlenecks.
  • To check the internal monitoring of routers, install an agent. On the internal monitoring page, the Cloud analyzes utilizations of CPUs, memories, and disks of all VM instances under the current zone. In addition, the Cloud provides a real-time monitoring display of top 5 resources by taking average CPU utilization, memory utilization, memory free in percent, used disk capacity in percent, and disk free in percent as performance metrics. Different colors of real-time percentage ranks and progress bars will directly indicate resource utilizations or performance bottlenecks.
• VIP tab page:

  On the VIP tab page, the Cloud analyzes network transmission performances of all VIPs under the current zone. In addition, the Cloud provides a real-time monitoring display of top 5 resources by taking network in (bytes), network out (bytes), network packets in (count), and network packets out (count) as performance metrics. Different colors of real-time percentage ranks and progress bars will directly indicate performance bottlenecks of some VIPs, as shown in VIP Performance TOP5.

• L3 network tab page:

  On the L3 network tab page, the Cloud analyzes IP resource utilizations of all L3 networks under the current zone. In addition, the Cloud provides a real-time monitoring display of top 5 resources by taking used IP in percent, used IP count, available IP in percent, and available IP count as performance metrics. Different colors of real-time percentage ranks and progress bars will directly indicate IP resource utilizations of L3 networks, as shown in L3 Network Performance TOP5.

Capacity Management provides a direct display of core resource capacity statistics on the cloud. With Capacity Management, various storage metrics on the Cloud are analyzed and rearranged to display detailed capacities of core resources in card. In addition, Top 10 resource capacities are displayed so that you can directly manage resource utilizations on the cloud.

The Capacity Management page mainly includes the following two sections:

• Upper section: Display detailed capacities of various core resources in card, including primary storages, backup storages, compute nodes, VM instances, volumes, images, snapshots, and management nodes.
• Lower section: Sort top 10 capacities of various core resources, including hosts, primary storages, backup storages, VM instances, images, VM instances, volumes, and snapshots.

Note:

• The resource capacities displayed in this page are all actual physical capacities of your resources.
• The data on this page are all static. To obtain the latest data, refresh this page each time when you go to this page.
• Currently, capacity statistics of primary storages can be analyzed and provided, such as LocalStorage, Shared Block, and Ceph.
• Currently, capacity statistics of backup storages can be analyzed and provided, such as ImageStore and Ceph.
