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
•
EsxDiskPolicyCheck.applyFitting
•
HypervDiskPolicyCheck.applyFitting
•
DasDiskPolicyCheck.applyFitting
•
SoftwarePolicyCheck.applyFitting
Writing a new rule file
Open a new drl file in a text editor, add the different sections of a rule file (as shown in
), and add the new rule logic.
•
Package—The name of the package and is always com.hp.hpio.controller.policy.
•
Import—Declares the use of any other Java classes required to write the rule business logic.
•
Rules:
— You can define multiple rules in a single rule (.drl) file.
— Each rule contains the business logic that you would like to execute in your rule.
— The INIT rule is a sample structure that you can duplicate and use as a starting point
to define your own rule.
You can also use tools such as Eclipse (
) to
write rule files by including the Drools Eclipse plug-in to the create rule project and including
the required Insight Orchestration libraries to the project. Using Eclipse helps with syntax
highlighting and auto code completion.

Example: Custom rule
rule "CustomRule1"
when
$pVO : PolicyExecutionVO( );
$resLst : List();
/* --------------- CUSTOM LOGIC ------------------ */
// Get service entity and resource objects.
$logicalSubnet : LogicalSubnet();
