Performing a Health Check
Scenario
To ensure that cluster parameters, configurations, and monitoring are correct and that the cluster can run stably for a long time, you can perform a health check during routine maintenance.
A system health check includes MRS Manager, service-level, and host-level health checks:
- MRS Manager health checks focus on whether the unified management platform can provide management functions.
- Service-level health checks focus on whether components can provide services properly.
- Host-level health checks focus on whether host indicators are normal.
The system health check includes three types of check items: health status, related alarms, and customized monitoring indicators for each check object. The health check results are not always the same as the Health Status on the portal.
Procedure
- Manually perform the health check for all services.
On the MRS details page, choose Management Operations > Start Cluster Health Check.
For the operations on MRS Manager of MRS 1.7.2 or earlier, see Performing a Health Check; for the operations on FusionInsight Manager of MRS 3.x or later, see Overview.
- The cluster health check includes Manager, service, and host status checks.
- To perform cluster health checks, you can also choose System > Check Health Status > Start Cluster Health Check on MRS Manager.
- To export the health check result, click Export Report in the upper left corner.
- Manually perform the health check for a service.
- On the MRS cluster details page, click Components.
