Viewing Cluster Static Resources

Scenarios

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.

MRS cluster administrators can view the monitoring indicators of resources used by each service in the static service pool on FusionInsight 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

After the multi-tenant function is enabled, the CPU, I/O, and memory usage of all HBase instances can be centrally managed.

Procedure

On FusionInsight Manager, choose Cluster > Name of the desired cluster > Static Service Pool Configurations.
In the configuration group list, click a configuration group, for example, default.
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.
In the Chart, view the indicator data chart of cluster service resource usage.
- You can click Add Service to Chart to add static service resource data of specific services (up to 12 services) to the chart.
- For details about how to manage a single chart, see Managing the Monitoring Indicator Report.
