Configure Incident Dampening Settings for a Node Group (SNMP Trap Incident)

Use this attribute to temporarily disable an incident's Dampening settings:

Disable  = Temporarily disable the selected configuration.

Enable  = Enable the selected configuration.

Specifies the number of minutes to be used for the dampen interval.

The Payload Filter Editor enables you to create expressions that further refine the filters used to select the incidents to be suppressed, enriched, or dampened. Make sure to design any complex Payload Filters offline as a Boolean expression first. This method can help to minimize errors when entering your expressions using the Payload Filter editor.

When creating a Payload Filter, note the following:

• Payload Filter expressions for the like and not like operators use the syntax defined for java regular expressions (java.util.regex Pattern class).
• You must use a ciaName that already exists in the trap or event you are configuring.
• Each set of expressions associated with a Boolean Operator is treated as if it were enclosed in parentheses and evaluated together.
• View the expression displayed under Filter String to see the logic of the expression as it is created.

• The AND and OR Boolean Operators must contain at least two expressions as shown in the example below.

  The following example filters incidents on voltage state:

  AND
    ciaName = .1.3.6.1.4.1.9.9.13.1.2.1.7
    ciaValue = 5

  NNMi evaluates the expression above as follows:

  (ciaName = .1.3.6.1.4.1.9.9.13.1.2.1.7 AND ciaValue = 5)

  NNMi finds all incidents with a varbind .1.3.6.1.4.1.9.9.13.1.2.1.7 value of 5.

  When you use ciaName and ciaValue in a Payload Filter, you must enter the ciaName and ciaValue as a pair as shown in the preceding example.

• The placement of your cursor and the subsequent text that is selected is important when performing operations using the Payload Filter Editor. For example, you append to, replace, or change the indentation of the expression that is selected.
• The placement of your cursor and the subsequent text that is selected is especially important when adding your Boolean operators.

• You can include more than one varbind in the same Payload Filter expression as shown in the following example:

  ((ciaName like \Q.1.3.6.1.4.1.9.9\E.* AND ciaValue = 25) AND (ciaName like \Q.1.3.6.1.2.1.2.2.1.1.3\E.* AND ciaValue = 3))

  In this example, a given trap must meet each of the following criteria:
  

  • Contain a varbind whose Object Identifier (OID) matches the regular expression \Q.1.3.6.1.4.1.9.9\E.* and has a value of 25.
  • Contain a varbind whose OID matches the regular expression \Q.1.3.6.1.2.1.2.2.1.1.3\E.* and has a value of 3.

The attribute name on which NNMi searches. Filterable attributes include the following:

• ciaName
• ciaValue
• sourceName

Valid operators are described below.

• = Finds all values equal to the value specified.

  Example: ciaName=.1.3.6.1.4.1.9.9.13.1.2.1.7 matches any incident that contains a varbind with the name value of .1.3.6.1.4.1.9.9.13.1.2.1.7.

• != Finds all values not equal to the value specified.

  Example: ciaName! = .1.3.6.1.4.1.9.9.13.1.2.1.7 matches any incident that contains a varbind with a name value other than 1.3.6.1.4.1.9.9.13.1.2.1.7.

• < Finds all values less than the value specified.

  Example: ciaValue < 6 matches any incident that contains a varbind with a value less than 6.

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

  Example: ciaValue <= 6 matches any incident that contains a varbind with a value less than or equal to 6.

• > Finds all values greater than the value specified.

  Example: ciaValue > 4 matches any incident that contains a varbind with a value greater than 4.

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

  Example: ciaValue >= 4 matches any incident that contains a varbind with values greater than or equal to 4.

• between Finds all values equal to and between the two values specified.

  Example: ciaValue between

  

  matches any incident that contains a varbind value equal to or greater than 1 and equal to or less than 4.

  As shown in the example, each value must be entered on a separate line.

• in Finds any match to at least one value in a list of values.

  Example:

  ciaValue in

  

  matches any incident with a varbind value of either 4 or 5.

  As shown in the example, each value must be entered on a separate line.

  NNMi displays the list of attributes using comma-separated values enclosed in parentheses, for example (4, 5). However, the comma-separated list is used only for display purposes. The actual delimiter is the new line.

• is not null Finds all non-blank values.

  Example: ciaValue is not null matches any incident with a varbind that contains a value.

• is null Finds all blank values.

  Example: ciaValue is null matches any incident with a varbind that does not contain a value.

• like Finds matches using the syntax defined for java regular expressions. See the Pattern (Java Platform SE6) API documentation at:

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

  The period (.) character means any single character of any type at this location.

  To include literal string values in the Value attribute, enclose the string value in \Q<literal_value>\E as shown in the Examples listed below.

  Example:

  ciaName like \Q.1.3.6.1.4.1.9.9\E.* matches any incident that contains a varbind name value that begins with 1.3.6.1.4.1.9.9 and (optionally) ends with any number of characters.

  ciaValue like .*Chicago.* finds all traps or events that contain a varbind value that includes the string Chicago.

• not between Finds all values except those between the two values specified.

  Example: ciaValue not between 5 8 matches an incident that contains a varbind with the values less than 5 or greater than 8 .

• not in Finds all values except those included in the list of values.

  Example:

  ciaValue not in

  

  matches any incident that contains a varbind with values other than 1 and 2.

  As shown in the example, each value must be entered on a separate line.

  NNMi displays the list of attributes using comma-separated values enclosed in parentheses, for example, (1, 2). However, the comma-separated list is used only for display purposes. The actual delimiter is the new line.

• not like Finds all that do not have the values specified using the syntax defined for Java regular expressions. See the Pattern (Java Platform SE6) API documentation at:
  http://download.oracle.com/javase/6/docs/api/java/util/regex/Pattern.html for more information.

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

  The period (.) character means any single character of any type at this location.

  To include literal string values in the Value attribute, enclose the string value in \Q<literal_value>\E as shown in the Examples listed below.

  Example:

  ciaName not like \Q.1.3.6.1.4.1.9.9\E.* matches any incident that contains a varbind name value that does not begin with .1.3.6.1.4.1.9.9 and (optionally) ends with any number of characters.

  ciaValue not like .*Chicago.* finds all traps or events that do not contain a varbind value that includes the string Chicago.

The value for which you want NNMi to search.

Note the following:

• The values you enter are case sensitive.

• NNMi displays a variable number of value fields depending on the Operator selected. For example, the between Operator causes two value fields to be displayed.
• The between, in and not in operators require that each value be entered on a separate line.

Inserts the AND Boolean Operator in the selected cursor location.

Inserts the OR Boolean Operator in the current cursor location.

Can be used in any part of the Filter String to specify that NNMi should exclude interfaces with values that pass the expression that immediately follows the NOT.

For example, when evaluating the following expression, NNMi includes interfaces with (interface description) ifDesc containing VLAN, and excludes any Interfaces that have VLAN10 for the (interface name) ifName value: 

(ifDesc like VLAN AND NOT (ifName=VLAN10)) 

Used for filters that include Capabilities or Custom Attribute names and values in the Filer String.

Indicates that you want NNMi to consider interfaces that have Capabilities or Custom Attributes when evaluating the Filter String.

For example, when evaluating the following Filter String, NNMi includes interfaces with (interface description) ifDesc containing VLAN, as well as any Interfaces Custom Attribute Role value is LAN Connection to Oracle Server: 

(ifDesc like VLAN OR EXISTS((customAttrName=Role AND customAttrValue=LAN Connection to Oracle Server)))

Used for filters that include Capabilities or Custom Attribute names and values in the Filer String. Indicates that you want NNMi to consider interfaces that do not have any Capabilities or Custom Attributes when evaluating the Filter String, but exclude the interfaces that match the expression that follows the NOT EXISTS.

For example, when evaluating the following expression, NNMi includes interfaces with (interface description) ifDesc containing VLAN, and excludes any Interfaces that have the Custom Attribute Role and that Role value is LAN Connection to Oracle Server: 

(ifDesc like VLAN OR NOT EXISTS((customAttrName=Role AND customAttrValue=LAN Connection to Oracle Server)))

Deletes the selected expression.
