Configuring Metric Defaults in XML File Policies

The Metric page enables you to indicate default settings for all metrics generated by the policy.

These defaults affect all new and existing rules. You can override the defaults in individual rules if needed. If a rule contains empty event attributes, the agent will use the defaults for the new event.

To access

In the Operations Connector user interface, click in the toolbar. Then click Metric > XML File.

Alternatively, double-click an existing policy to edit it.

Click Defaults to open the Default Metric Attributes page.

Tasks

How to configure metrics defaults for XML file policies

This task describes how to configure metric attribute defaults for all metrics collected by this policy.

1. Define the metric attributes common to all metrics collected by this policy, such as metric class and name. All metrics in the Basic tab marked with a * are required. Advanced attributes are optional.

2. Optional. Use the Sample Data tab to drag XML properties (XML elements and attributes) and values to the attribute boxes. Alternatively, you can type the path to the XML property or value directly into the attribute box.

   XML properties use the following syntax: <$DATA:/<XMLProperty>>

   <XMLProperty> is the path from the root XML element of XML data to a specific XML element or attribute within that data. XML path uses slashes (/) as the path delimiters.

   Operations Connector replaces the XML property at runtime with the value of the specified XML element or attribute. If you insert an XML value, the value will be used.

   The Sample Data tab is empty if no sample data is loaded into Operations Connector or no XML data has been received for the policy.

3. Optional. Use the Mappings tab to add mapping definitions to the attribute boxes.

   Mappings are custom variables that you define in the mappings tab. The default name of the mapping variable is map<XMLProperty>, for example mapSeverity.

   Alternatively, type the custom variable into the attribute box using the following syntax:

   • Map Name list contains the map name of the variable: map<XMLProperty>, for example mapSeverity.

   • Input Data Property list item: <$DATA:/<XMLTag>/<XMLProperty>>

     For example, the custom variable mapSeverity has the following input data property: <$DATA:/PerformanceAlert/Severity> where Severity is a child element of PerformanceAlert.

4. Optional. Use the Operators tab to apply operators to the attribute values. Two functions are available:

   $MATCH(), to test a string or a variable against a pattern. The $MATCH function accepts three or four parameters:

   - the input string

   - the pattern definition

   - the output string if pattern matches on the input string

   - the output string if the pattern does not match (optional)

   Example: The data of the input field hostname start always with "TEST" (for example "TESTABC"). The $MATCH function to use the string after "TEST" is as follows:

   $MATCH(<$DATA:hostname>,TEST<*.prefix>,<prefix>)

   • <$DATETIME(FORMAT,VALUE)>, to convert the format of dates from the common format to the UNIX systems time (Epoch time) format.

     To apply operators to the attribute values, you can drag and drop them to a text field in the left pane of the same policy editor page. The appropriate tooltips are shown while performing this operation, which describe the role of the dragged operator.

5. Optional. Use the Indicators tab to add indicators to the source or target value fields. After loading the indicators from the connected OMi server, the Indicators tab shows a hierarchy of configuration item types.

6. Optional. In the Policy Variables tab, add policy variables to metric attributes. Operations Connector replaces the variables with the appropriate values in the generated metric.

   Use quotation marks to surround variables, for example "<$MSG_NODE>" or "<$MSG_GEN_NODE>", at least for those variables whose values can contain space characters.

UI Descriptions

Basic Tab (Default Attributes)

UI Element	Description
Data domain	The namespace of the integrated performance records, used in the Operations Agent store to avoid clashes. Example: "BSMCMetrics"
Metric class	Defines the metric class. Metric class and metric name are concatenated as the metric name that appears in the Operations Agent store and consumers. Example: "Windows CPU Monitor"
Metric name	Defines the metric name. Metric class and metric name are concatenated as the metric name that appears in the Operations Agent store and consumers. Example: "CPU Utilization"
Related CI	Contains the CI that is related to the metric (for example, oraclesid01@@node.example.com or C:@@server.example.com). Use the format <CI 1>:<CI 2>:...:<CI n>@@<hostname>. Best practices for related CIs It is necessary to differentiate between CIs that have a Composition relationship to a node, and those that do not have such a relationship: For “hosted on” CIs <key attribute 1>:<key attribute 2>:<key attribute n>@@<hostname> Typically, a “hosted on” CI is a sub-type of “Running Software”. For example, a CI of type websphereas has a Composition relationship to a node. For virtual CIs <key attribute 1>:<key attribute 2>:<key attribute n> A virtual CI does not have a strong containment relationship (Composition relationship) to node. An example of a typical virtual CI type is cluster. This CI type does not have a strong containment relationship to a node. If you have problems resolving non-hosted CIs, provide the RTSM ID of the desired CI by using the format UCMDB:<ci_uuid>. For more information about CI resolution in OMi, see the OMi Help.
Node	Used to identify a node-like CI to which the performance records are associated to. Example: "dbsys1.company.com"
Value	The actual performance value. It is automatically converted to a double-precision number. Example: 80
Time measured	The time stamp when the value was determined in the third-party system, expressed in the following formats: Integers.Operations Connector interprets integers in the policy source as seconds since 00:00:00 UTC on 1 January 1970 (UNIX system time). For example, 1276600333 is 15 June 2010, at 11:12:13. Use the $DATETIME function to convert it. For details about the function, see Configuring Event Defaults in Database Policies topic. Default time formats.Operations Connector by default interprets the following time formats: yyyy-mm-ddTHH:MM:SS (for example, 2010-06-15T11:12:13) mm/dd/yyyy HH:MM:SS (for example, 06/15/2010 11:12:13) Additional time zone formats are supported: yyyy-mm-ddTHH:MM:SS tz (for example, 2010-06-15T11:12:13 +3) mm/dd/yyyy HH:MM:SS tz(for example, 06/15/2010 11:12:13 -2) where tz is a number for the offsett to the UTC time zone. You can also use half or quarter hours (.25, .5, or .75, for example, 2010-06-15T11:12:13 -2.75). If you want to create your own pattern, you can store the time zone information in <@.tz> to match all above mentioned time zones.

Advanced Tab (Default Attributes)

UI Element	Description
Original metric name	The name of the metric as used on the third-party system. Example:
Unit	The unit of the metric values. Example: "MB"
Integration id	An ID, used to identify the source of the integration. Example: "DB-ORA"

Sample Data Tab

UI Element	Description
<Search Properties>	Entered search string is used to find an XML property or value. The list changes as you type; only matching items appear. To clear the search results, click .
XML Properties	Shows all XML elements and attributes that match an XML tag. The XML properties list is empty if no sample data has been loaded into the policy or if the sample data does not match any specified XML tags.
	Toggle Short/Full Path Notation. Shows or hides the full path to the XML property or value. The full path begins with the XML tag specified in the Source tab. The XML Properties section by default shows the short path to the XML property or value.
Values for '...'	Displays the values of the XML property selected in the XML Properties section.
	Find Matching Records. To find values that belong to more than one XML property, select the value and click . The XML Sample Data window opens and shows all XML properties that have the selected value.
	Toggle Deduplication. Shows or hides duplicate values.

Mappings Tab

UI Element	Description
<Mappings>	Displays the mapping definitions configured for the policy.

Operators Tab

Expressions and Functions	Description
$MATCH(<input>, <pattern>,<output_on_match>(,<output_on_no_match>))	Tests a string or variable against a pattern. The $MATCH function accepts three or four parameters: - the input string - the pattern definition - the output string if pattern matches on the input string - the output string if the pattern does not match (optional) Example: The data of the input field hostname start always with "TEST" (for example "TESTABC").
