The following information describes the Expression/destAttr metrics:
Specifies to use the vendor certification attributes of the ObjectID to define the MVEL expression to provide the value for the Indexes metric family attribute.
Recommendation: Set to INDEX.
Can be updated: Yes
Possible values: Any attribute that has <IsIndex>true</IsIndex>.
Effect of updating: Component indexing could change.
When does the update take effect: After component rediscovery
Required actions for updates to take effect: Update the metric family or change the vendor certification priority.
Specifies to use the vendor certification attributes to collect configuration data. This configuration data helps define the MVEL expression to provide the value for the Names metric family attribute.
Recommendation: Include as much information as necessary to identify an instance uniquely.
Can be updated: Yes
Possible values: String MVEL expression using available Attributes
Effect of updating: Component name change
When does the update take effect: After component rediscovery
Required actions for updates to take effect: Update the metric family or change the vendor certification priority.
(Optional) Specifies to use the vendor certification attributes to collect configuration data. This configuration data helps define the MVEL expression to provide the value for the Descriptions metric family. Not all metric families support a Descriptions attribute.
Recommendation: Include as much information that is available to describe an instance.
Can be updated: Yes
Possible values: String MVEL expression using available Attributes
Effect of updating: Component description change
When does the update take effect: Component rediscovery
Required actions for updates to take effect: Update the metric family or change the vendor certification priority.
Specifies to use the vendor certification attributes to collect configuration or performance data. This data is used to define the MVEL expression to provide the value for the metric family attribute.
Can be added: Yes, if the destAttr exists in the metric family.
Can be updated: Yes
Possible values: MVEL expression using available Attributes, producing a value that matches the type of the destination attribute.
Effect of updating: Polled value changes
When does the update take effect: Next poll
Required actions for updates to take effect: None
The metric family exposes URIs (such as, {http://im.ca.com/normalizer}FamilyName.AttributeName), which are separately referred to in the ExpressionGroup. The ExpressionGroup/destCert property is set to the URI (for example, {http://im.ca.com/normalizer}FamilyName), and the Expression/destAttr is set to AttributeName.
