Checking the Static Resources of an MRS Cluster

The big data management platform can manage and isolate service resources that are not running on YARN using static service resource pools. The system supports time-based automatic adjustment of static service resource pools. This enables the cluster to automatically adjust the parameter values at different periods to ensure more efficient resource utilization.

System administrators can view the monitoring indicators of resources used by each service in the static service pool on Manager. The monitoring indicators are as follows:

  • CPU usage of services
  • Total disk I/O read rate of services
  • Total disk I/O write rate of services
  • Total used memory of services

Checking Static Resources (MRS 3.x and Later)

  1. Log in to FusionInsight Manager and choose Cluster > Static Service Pool Configurations.
  2. In the configuration group list, click a configuration group, for example, default.
  3. Check the system resource adjustment base values.

    • System Resource Adjustment Base indicates the maximum volume of resources that can be used by each node in the cluster. If a node has only one service, the service exclusively occupies the available resources on the node. If a node has multiple services, all services share the available resources on the node.
    • CPU indicates the maximum number of CPUs that can be used by services on a node.
    • Memory indicates the maximum memory that can be used by services on a node.

  4. In Chart, view the metric data of the cluster service resource usage.

Checking Static Resources (MRS 2.x and Earlier)

  1. On MRS Manager, click System. In the Resource area, click Configure Static Service Pool.
  2. Click Status.
  3. Check the system resource adjustment base values.

    • System Resource Adjustment Base indicates the maximum volume of resources that can be used by each node in the cluster. If a node has only one service, the service exclusively occupies the available resources on the node. If a node has multiple services, all services share the available resources on the node.
    • CPU(%) indicates the maximum number of CPUs that can be used by services on a node.
    • Memory(%) indicates the maximum memory that can be used by services on a node.

  1. Check the cluster service resource usage.

    In the chart area, select All services from the service drop-down list box. The resource usage status of all services in the service pool is displayed.

    Effective Configuration Group indicates the resource control configuration group used by the cluster service. By default, the default configuration group is used at all time every day, indicating that the cluster service can use all CPUs and 70% memory of the node.

  2. View the resource usage of a single service.

    In the chart area, select a service from the service drop-down list box. The resource usage status of the service is displayed.

  3. You can set the interval for automatically refreshing the page.
  4. In the Period area, select a time range for viewing service resources.
  5. Click View to view the service resource data in the corresponding time range.
  6. Customize a service resource report.

    1. Click Customize and select the service source indicators to be displayed.
    2. Click OK to save the selected monitoring metrics for display.

      Click Clear to cancel all the selected monitoring metrics in a batch.

  7. Export a monitoring report.

    Click Export. MRS Manager will generate a report about the selected service resources in a specified time of period. Save the report.

    To view the curve charts of monitoring metrics in a specified period, click View.
