A health policy is the definition of specific health criteria that
you want your WebSphere Extended Deployment to protect itself against. The
health management function uses the defined policy to search the environment
for software malfunctions.
Before you begin
- To create a health policy, you must have configurator or administrator
administrative privileges. The health controller must be enabled.
About this task
Health policies work with the health management controller to monitor
the operation of the servers in your environment. When the health management
controller detects that your servers are not meeting a defined health policy,
you can take action to fix the problem. You can notify the administrator of
problems, or WebSphere Extended Deployment can fix the problems automatically.
Procedure
- In the administrative console, click Operational policies >
Health policies > New.
- Define the health policy general properties. These properties
include the health policy name, description, and the condition.
Remember: The
excessive request timeout and storm drain conditions do not apply to Java
Message Service (JMS) and Internet Inter-ORB Protocol (IIOP) traffic.
- Define health policy health condition properties. Health
policy conditions include the following properties:
- Set properties that pertain to the health condition that you selected
are displayed.
- Choose a reaction mode. Supervise mode gives more control to the
administrator, so that they can approve or reject actions before they are
taken.
- Select the actions to take when the health policy conditions are not met.
The available actions depend on the health condition type.
- Select the memberships to monitor for your health policy.
Layers of logic can apply to monitored memberships. For example, you
might want to apply a specific health policy to each member of a cluster and
to an application server outside of the cluster.
- Review and save your health policy.
Results
You created a health policy and applied that policy to a target environment.
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, then 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 System administration > 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.
