Performance TOP5

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.

In the navigation pane of the ZStack Private Cloud UI, choose Platform O&M > Performance TOP5. Then, the Performance TOP5 page is displayed. This page includes five tab pages: host, VM instance, router, L3 network, and VIP.
  • 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.

    You can click one of the top 5 resource names to check resource details, as shown in Top 5 Resource Details.

  • 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.
  • 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.

  • 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.

More Information

  • On the performance top 5 page at the upper right, select the time drop-down box to set data collection periods for host, VM instance, router, and VIP. Optional period: 1 minute | 1 hour | 24 hours | 1 week, and 1 month. The L3 network tab page does not have data collection period settings.
  • A regular account can check the performance top 5. Similar to an admin, the regular account can directly and easily check top 5 information of various monitoring metrics such as VM instances, routers, VIPs, and L3 networks on the performance top 5 page. In this regard, you can directly manage the real-time health state of resources on the Cloud, and can quickly locate problems.
  • A project member can also check the performance top 5. Similar to an admin, the project member can directly and easily check top 5 information of various monitoring metrics such as VM instances, routers, L3 networks, and VIPs on the performance top 5 page. In this regard, project member can directly manipulate the real-time health state of resources on the Cloud, and can quickly locate problems.
