Configuring health management

Health management is the process by which the dynamic operations of WebSphere Extended Deployment monitor and manage servers that might fail, to preserve an optimal server environment.

Before you begin

Create the environment that you want to monitor. When you create a health policy, you select members for the policy, so these members must exist before you create the policy.

About this task

Health management is the ability of the system to take a policy-driven approach to monitoring the application server environment and to take action when certain criteria are discovered.

Procedure

  1. Verify that the health controller is enabled.

    The health controller is the autonomic manager that monitors health conditions. The health controller is enabled by default and is required for health management.

    In the administrative console, click Operational policies > Autonomic managers > Health controller. Verify that the health controller is enabled and configure the other settings for the health controller. For more information about configuring the health controller, see Enabling and disabling health management .
  2. Create health policies. Health policies define the health conditions that you want to monitor in your environment, and the health actions to take if these conditions are not met. You can define multiple health policies to monitor the same set of servers in your cell. For more information about creating health policies, see Creating health policies .

Results

The health controller monitors the conditions that you defined for the health policy members, and takes the defined actions on the members when the conditions in the health policy breach.

What to do next

If you chose the Supervise reaction mode, you receive recommendations to improve your health conditions. These recommendations display as runtime tasks that you can accept, deny, or close. To manage runtime tasks, click Runtime Operations > Task Management > Runtime Tasks in the administrative console. If you chose the automatic reaction mode, actions to improve the health of your environment occur automatically.
