You can set the health of the object by selecting or deselecting the health check box.
Changing the value in the Development Client in this way has an immediate effect unless
the value is overriden by an attached policy (this follows the normal rules of policy
inheritance).
Set by using a discovery job (a job periodically scheduled to run on resources and to explicitly
set the health fact, much like it sets other discovered facts). In this case, the discovery job
performs a setFact (
Set by using a policy. This method has little practical use except for locking the value
immediately to override the setting (that is, the typical policy behavior) on the grid object:
<policy>
</policy>
Set by using a computed fact. This method can be used to monitor the health according to a
computed value. One applied scenario for this method might be a computed fact that performs
a statistical analysis of historical load data, perhaps provided by the Metrics facility.
Set automatically by using a health constraint. This is the most practical use and is best
illustrated with examples.
