Resource Monitoring

Updated at: Mar 25, 2021 GMT+08:00

Some services in the cluster provide service-level resource monitoring metrics. By default, the monitoring data of the latest 12 hours is displayed. You can click to customize a time range. The default time ranges are as follows: 12 hours, 1 day, 1 week, and 1 month. You can click to export the corresponding report information. If a monitoring item has no data, the report cannot be exported. Table 1 lists the services and monitoring items that support resource monitoring.

Log in to FusionInsight Manager, choose Cluster > Name of the desired cluster > Services, and click Resource. The resource monitoring page is displayed.
