Enabling Health Alerts

You can enable alerts when the health of a role, service, or host crosses a threshold.

Minimum Required Role: Limited Cluster Administrator (also provided by Full Administrator and Cluster Administrator), and Cluster Administrator for host-level changes (also provided by Full Administrator).

  1. Select Clusters > cluster_name > service_name or open the page for a role or host.

    If you intend to work on the Cloudera Management Service, select Clusters > Cloudera Management Service.

  2. Click the Configuration tab.
  3. Select Scope > role_name or service_name (Service-Wide) or Host.
  4. Click the Monitoring category.
  5. Select the Enable Health Alerts for this Role, Enable Service Level Health Alerts, or Enable Health Alerts for This Host checkbox, depending on whether you are configuring a role, service, or host.

    The Enable Health Alerts for this Role checkbox controls alerts for all role-level health tests of the corresponding role. Similarly, the Enable Service Level Health Alerts checkbox enables alerts based on all service-level health tests of the corresponding service, and the Enable Health Alerts for This Host checkbox applies to all health tests of the corresponding host. You can differentiate among role, service, and host health tests by the status page they appear on (role, service, and host respectively).

    For a comprehensive list of health tests corresponding to each role type, service type, and host, see Cloudera Manager Health Tests documentation. Each listed health test can contribute to alerts, depending on whether you select the corresponding role-level, service-level, or host-level checkbox.
