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 controller to monitor
the operation of the servers in your environment. When the health
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 health
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:
- 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.
