Chapter 4 Managing RME Device Groups Using Group Administration
Understanding the Grouping Rules
Understanding the Grouping Rules
Every group is defined by a set of rules. A rule set contains a Boolean combination of individual rule
expressions.
Rules are created to filter in the devices that you want to include to the group, and to filter out those that
you do not want in the group.
When determining which devices belong to a group, Group Management compares device information
to the rule. If the information on a device satisfies all the requirements of the rule then it is placed in the
group.
The devices are filtered based on the data present in the RME Inventory database.
One or more rule expressions can be applied to form a rule.
Each rule expression contains the following:
<object type>.<variable> <operator> <value>
For examples on creating rules, see Examples for Grouping Rules.
Field/Buttons Description
OR, AND, EXCLUDE Logical operators.
• OR—Include objects that fulfill the requirements of either rule.
• AND—Include only objects that fulfill the requirements of both rules.
• EXCLUDE—Do not include these objects.
This field appears only after a rule expression is added in the Rule Text box.
Object Type The type of object (device) that is used to form a group. All RME rule
expressions begin with the same Object Type, :Device.
Vari ab le Device attributes, based on which you can define the group.
SeeRME Group Attributes
Operator The operator to be used in the rule. The list of possible operators changes
based on the Variable selected.
When using the equals operator the rule is case-sensitive.
Valu e The value of the rule expression. The possible values depend upon the
variable and operator selected. Depending on the operator selected, the
value may be free-form text or a list of values.
The wildcard characters are not supported.
Add Rule Expression Used to add the rule expression to the group rules.
Rule Text Displays the rule.
Check Syntax Verifies that the rule syntax is correct.
Use this button to verify the syntax of the rule created before proceeding to
the next step.
View Parent Rules Used to view the parent group rules.
All parent group rules apply to the subgroups.
