Configure a Source Object Filter for a Causal Rule

The Source Filter tab enables you to create a filter to specify which Source Object should be used for the Parent Incident that is generated for this Causal Rule.

Note Create only one Source Object Filter for a Causal Rule. If you select Use Child Incident's Source Object for Parent, NNMi ignores any Source Object Filter you configure.

To configure a Source Object Filter for a Causal Rule:

  1. Navigate to the Causal Rules tab.
  2. From the Causal Rules table toolbar, do one of the following:

    • To create a Causal Rule, click the New icon, and continue.
    • To edit a Causal Rule, click the Open icon in the row representing the Causal Rule you want to edit, and continue.
    • To delete a Causal Rule, click the  Delete icon.
  3. Create your Causal Rule. (See Configure a Causal Rule.)
  4. Create your Child Incident Configuration . (See Configure a Child Incident for a Causal Rule.)
  5. Optional. Configure a Child Incident Filter. (See Configure a Child Incident Filter for a Causal Rule.)
  6. Optional. Configure a Source Object Filter. (See the tables that follow, starting with Filter Editor Settings).

    Filter Editor Settings
    Setting Description
    Attribute

    The Attribute on which NNMi searches. See Valid Attributes below for a description of valid Attributes.

    Operator Use this Operator to establish the relationship between the Attribute and Expression. See Valid Operators in the table below for the description of each valid Operator.
    Expression Use the Expression to complete the criteria for the Parent Incident configuration. See Valid Expressions below for more information.
  7. Optional. Configure a Source Node Filter. (See Configure a Source Node Filter for a Causal Rule.)
  8. Click  Save and Close to save your changes and return to the previous form.

Valid Attributes
Attribute Description
Attribute

The Attribute on which NNMi searches. Valid attributes other than Source Node attributes depend on the Incident's Source Object. NNMi checks the Source Node as well as the Source Object for any Capability value.

Note the following when specifying Attributes:

  • Boolean Attributes begin with "is" and must contain the value true or false.
  • If you use attributes that are valid for the Source Node, NNMi uses the Source Node when comparing values. If you use attributes that are valid for the Source Object, NNMi uses the Source Object when comparing values. You cannot use attributes that are valid for the Source Node and Source Object in the same filter.
  • When using attributes for a Source Object, the attribute must be valid for the incident's Source Object or NNMi does not find a match. For example, if you use the hostedOn attribute and the Source Object is not an interface, the correlation does not occur.

  • Tip To check a Source Object for an incident, select the incident of interest, then select Open from the Lookup menu for the Source Object, and examine the Source Object form.

    A Source Object attribute value of None indicates that NNMi cannot identify the Source Object or the Source Object is a Node. If you want to match the incident, use one or more Source Node attributes.

Valid Operator Values
Operator Description
=

Finds all values equal to the value specified.

!=

Finds all values not equal to the value specified.

<

Finds all values less than the value specified.

<=

Finds all values less than or equal to the value specified.

>

Finds all values greater than the value specified.

>=

Finds all values greater than or equal to the value specified.

is not null

Finds all non-blank values.

is null

Finds all blank values.

like

Finds matches using wildcard characters and the question mark.

The asterisk (*) character means any number of characters of any type at this location.

The question mark (?) character means any single character of any type at this location.

not like

Finds all matches that do not have the values specified.

The asterisk (*) characters means any number of characters of any type at this location.

The question mark (?) character means any single character of any type at this location.

Valid Expressions
Attribute Description
Expression

The value or pattern for which you want NNMi to search.

Note the following:

  • The expression can include a valid Attribute.

  • The value or pattern you want to match is case sensitive.

  • When entering the value for ifSpeed, use the actual numeric value for the interface speed. For example, use 10000000 for ifSpeed 10 Mbps.
