Performance Analysis

Performance Analysis displays the performance metrics of key resources monitored externally or internally in the Cloud. You can view the performance analysis or export the analysis report as needed to improve the O&M efficiency.

View Performance Analysis

On the main menu of ZStack Cloud, choose Platform O&M > Cloud Monitoring > Monitoring Chart > Performance Analysis. Then, the Performance Analysis page is displayed.

Figure 1. View Performance Analysis


The Performance Analysis page consists of filters and analysis reports.
  • Filters: Supports basic filtering and advanced filtering.
    • Basic filtering: Allows you to filter by resource, monitoring methods, and time spans.
      • Resource: Supports VM instances, VPC vRouters, hosts, backup storages, L3 networks, and virtual IPs.
      • Monitoring method: Supports external monitoring and internal monitoring.
        • External monitoring: Obtains the VM performance data, such as the CPU, memory, disk I/O, and NIC data from the host by using libvirt.
        • Internal monitoring: Obtains the VM performance data, such as the CPU, memory, and disk capacity directly by using the agent and pushes the data to the host. To using internal monitoring, install the agent first.
        Note: The memory data obtained by using internal monitoring is more accurate than that obtained by external monitoring. Therefore, we recommend that you use internal monitoring to monitor the memory data.
      • Time span: You can select a time span to view the monitoring data. Available time spans: 15 minutes, 1 hour, 1 week, and custom.
    • Advanced filtering: Allows you to further filter by filter item, resource scope, and owner scope.
      • Filter item: Allows you to sort and view resources based on monitoring metrics and metric values (for example, CPU utilization >= 75%).
      • Resource range: Allows you to view the monitoring information of all resources on the Cloud or specify a resources to view its own monitoring information.
      • Owner range: Allows you to view the monitoring information of all owners in the Cloud or specify an owner to view the monitoring information.
  • Analysis report: Generates an analysis report based on the filter conditions.
    • Allows you to sort the items by resource name or monitoring metric.
    • Allows you to export all the report information or export the information on the current page in CSV format.
    • Allows you to customize the number of items to be displayed on each page. By default, 10 items are displayed per page.
    Note:
    • The VM analysis report page allows you to stop a VM instance.
    • The VM analysis report page allows you to filter VM instances based on the VM state.
    • The VM/VPC vRouter analysis report allows you to customize the columns to be displayed.
    • When you export a VM or VPC vRouter analysis report, you can choose to export the average, maximum, or minimum values of the metrics as needed.
The following table lists the monitoring metrics of each resources.

Export Analysis Report

You can export all the analysis information of a resource or only information on the current page based on the filter conditions. For VM instance and VPC vRouters, you can customize the monitoring metrics to be exported and choose to export their average values, maximum values, or minimum values as needed.

On the main menu of ZStack Cloud, choose Platform O&M > Cloud Monitoring > Monitoring Chart > Performance Analysis. Then, the Performance Analysis page is displayed. Taking VM instance as an example, on the analysis report area, click Export CSV and choose Current Page or All. Then, the export page is displayed.

Figure 2. Export Analysis Information on the Current Page


  • The export page displays the selected resource, monitoring method, time span, and all the monitoring metrics of the resource.
  • By default, metrics displayed in the VM/VPC vRouter list are automatically selected. You can deselect them or select the average, maximum, or minimum value of other metrics.
  • You can select all the average, maximum, and minimum values or empty your selections with on click.

Capacity Management
