Performance Analysis

Performance Analysis is a performance statistics page designed for O&M personnel. This page takes resources as a unit to directly and simply display monitoring metrics of various resources, such as VM instances, routers, hosts, L3 networks, VIPs, and backup storages at different time ranges. With Performance Analysis, the O&M personnel can directly manipulate the health status of resources on the Cloud.

In the navigation pane of the ZStack Private Cloud UI, choose Platform O&M > Performance Analysis. Then, the Performance Analysis page is displayed. This page contains six tab pages: VM instance, router, host, L3 network, VIP, and backup storage.
  • VM instance or router tab page:
    The VM instance or router page includes external monitoring and internal monitoring.
    • On the external monitoring page, the Cloud analyzes utilizations of CPUs, memories, disks, and network resources of all VM instances or routers under the current zone. In addition, the Cloud provides a direct display of average CPU utilization, memory utilization, disk read/write speed, and NIC out/in speed. In this regard, you can manage directly performance metrics of resources within the Cloud, as shown in Performance Analysis of VM/Router External Monitoring.
      Figure 1. Performance Analysis of VM/Router External Monitoring


    • On the internal monitoring page, the Cloud analyzes the plug-in state, operating system, default IP, CPU utilization, memory utilization, and disk used capacity of all VM instances or routers under the current zone. In addition, the Cloud provides a direct display of the plug-in state, operating system, default IP, CPU utilization, memory utilization, and disk used capacity as performance metrics. In this regard, you can manipulate directly performance metrics of resources within the Cloud, as shown in Performance Analysis of VM/Router Internal Monitoring.

    Note:
    • On the VM instance tab page, you can click Stop to stop VM instances.
    • If you have multiple CPUs, CPU utilizations on the external monitoring page might probably exceed 100%.
    • For memory data, internal monitoring is more accurate than external monitoring. We recommend that you use internal monitoring to monitor memory data.
  • Host tab page:
    On the host tag 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 direct display of the average CPU utilization, memory utilization, disk read speed, disk write speed, NIC in speed, and NIC out speed as performance metrics. In this regard, you can manipulate directly performance metrics of resources within the Cloud, as shown in Figure 3.

  • L3 network tab page:
    On the L3 network tab page, the Cloud analyzes IP utilizations of all L3 networks under the current zone. In addition, the Cloud provides a direct display of the used IP count, used IP in percent, available IP count, and available IP in percent as performance metrics. In this regard, you can manipulate directly IP resource utilizations of the current L3 networks within the Cloud, as shown in Figure 4.

  • 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 direct display of the inbound traffic in bytes, inbound traffic in packages, outbound traffic in bytes, and outbound traffic in packages. In this regard, you can manipulate directly transmission bottlenecks that occur in some VIPs, as shown in Figure 5.

  • Backup storage tag page:
    On the backup storage tab page, the Cloud analyzes capacities of all backup storages under the current zone. In addition, the Cloud provides a direct display of the available backup storage capacity in percent as a performance unit. In this regard, you can manage directly storage utilizations of backup storages, as shown in Figure 6.

More Information

  • You can customize data ranges (defaults to 1 minute). By clicking the time range button at the upper right, you can specify the start time and end time to check data of performance analysis within different time ranges.
  • The left-side filter allows you to check custom performance analysis list according to the resource range and the filter entry. Specifically, a VM instance, router, and VIP allow you to display a custom performance analysis list according to owners.
  • By default, each page displays 20 pieces of information. You can choose to display resource counts on a single page. Options: 10 | 20 | 50 | 100. In addition, you can turn your pages by clicking the left arrow button and the right arrow button.
  • By clicking the download button at the upper right, you can export a CVS file of resource information.
  • A regular account or project member can check performance analysis. Similar to an admin, the regular account or project member can directly and easily check real-time utilizations of VM instances, routers, L3 networks, and VIPs on the performance analysis page.
  • A time range can be selected to check performance analysis data. Note that these data are average values collected within the selected time range. To obtain the currently detailed resource data, go to the resource details page.
