Enabling and disabling health management

Health management monitoring is enabled by default. You can enable or disable health management monitoring.

Before you begin

The health monitor uses health policies. A health policy is a combination of health conditions and actions. Health conditions define triggers from which the system can protect itself, for example, a memory leak. Health actions are the specific steps that the system takes when a health condition is triggered. For example, with a memory leak condition, the health action can be to restart the associated servers . A number of predefined health conditions are installed with the product. You can use the predefined health conditions to create default health policies. In addition to these broad default health policies, you can define specific policies that apply for your environment. For more information about the default health policies, read about health management. For more information, read about creating health policies.

Depending on your administrative role, you are allowed specific privileges when configuring the autonomic managers. The following list shows the administrative roles and privileges for configuring the autonomic managers:

Monitor: Can view the information.

Operator: Can view the information on the configuration tab. Can change the settings on the runtime tab.

Configurator: Can change the configuration but not the runtime settings.

Administrator: Has all privileges.
