Configure health management
Health management is the process by which the dynamic operations of WebSphere Virtual Enterprise monitor and manage servers that might fail, to preserve an optimal server environment.
Before you begin
Create the environment 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
- 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- Define health policy custom actions.
By default, you can define the following actions to occur when a health condition breaches:
- restart the server
- take thread dumps
- take heap dumps
- place the server into or out of maintenance mode
If we need a health action that is not covered by these default health actions, create a custom action. You can then select the custom action when you create a health policy.
- If you are configuring thread dumps as your health policy action on a z/OS system, specify the _CEE_DMPTARG custom property on your servers.
- Create health policies
Health policies consist of health conditions and health actions. When a health condition is triggered, the health action for the policy is invoked. You can create multiple health policies for a server or set of servers.
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...
