Customizing existing rules
The advantage of providing a rules based allocation fitting process is that you can customize the
existing rules to change the business logic by modifying the CUSTOM LOGIC portion of the code.
You can modify or delete existing rules, or add new custom rules. Rules are written in Java and
the Drools syntax.
Available hooks for customizing:
•
SubnetPolicyCheck.applyFitting
•
AttributeBasedSubnetPolicyCheck.applyFitting
•
SpecifiedSubnetPolicyCheck.applyFitting
•
AutomaticIpAddressPolicyCheck.applyFitting
•
StaticIpAddressPolicyCheck.applyFitting
•
DhcpIpAddressPolicyCheck.applyFitting
•
PhysicalServerPolicyCheck.applyFitting
•
PhysicalBootDiskPolicyCheck.applyFitting
•
NPIVDataDiskPolicyCheck.applyFitting
•
VirtualServerPolicyCheck.applyFitting
