Performing a Host Health Check

Scenario

If the running status of a host is not Normal, you can perform health checks on the host to check whether some basic functions are abnormal. During routine O&M, you can perform host health checks to ensure that the configuration parameters and monitoring of each role instance on the host are normal and can run stably for a long time.

Procedure

  1. Log in to FusionInsight Manager.
  2. Click Hosts.
  3. Select the check box of the target host.
  4. Select Health Check from the More drop-down list to start the health check.

    To export the result of the health check, click Export Report in the upper left corner. If any problem is detected, click Help.
