Performing a Health Check

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

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.
    1. Click Services.
    2. Choose More > Start Cluster Health Check to start the health check for the cluster.
    • The cluster health check includes Manager, service, and host status checks.
    • To perform cluster health checks, you can also choose System > Check Health Check > 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.
    1. Click Services. In the services list, click the desired service name.
    2. Choose More > Start Service Health Check to start the health check for the service.
  • Manually perform the health check for a host.
    1. Click Hosts.
    2. Select the check box of the host for which you want to check the health status.
    3. Choose More > Start Host Health Check to start the health check for the host.
  • Automatically performing a health check
    1. Click System.
    2. Click Check Health Status under Maintenance.
    3. Click Configure Health Check to configure automatic health check items.
