Metrics Definition
Following the approach proposed by the Governance Interoperability Framework, saving metrics information for service objects is accomplished by publishing a uddi:tModel. This means that a uddi:tModel holding the metrics information is published and attached to the given uddi:businessService.
Following is a simple uddi:tModel the metrics information:
<tModel tModelKey="uddi:3d32ac10-5dd1-11da-88b8-51d47e6188b2" deleted="false"
xmlns="urn:uddiorg:api_v3">
<name>Metrics</name>
<description>Metrics of EchoAccessPoint</description>
<categoryBag>
<keyedReference
tModelKey="…(key of object type taxonomy)"
keyName="Metrics"
keyValue="Metrics"/>
<keyedReference
tModelKey="uddi:centrasite.com:management:metrics:total.request.count"
keyName="Count of hits"
keyValue="14"/>
</categoryBag>
</tModel>
The uddi:keyedReference of the uddi:categoryBag hold the metrics information. The following metrics are supported.
Total Request Count
Success Request Count
Fault Count
Average Response Time
Minimum Response Time
Maximum Response Time
Availability
Service Liveliness
For each of the supported metrics an according taxonomy is defined that represents the according value set.
For attaching a metrics uddi:tModel to a given uddi:service, a uddi:keyedReference is used, which references the metrics-reference taxonomy. Following is an example of a uddi:businessService that references a metrics uddi:tModel:
<businessService serviceKey="uddi:1d233560-5dc8-11da-88b7-51d47e6188b2"
businessKey="uddi:a2b32100-5ac0-11da-8540-e2406020853d"
xmlns="urn:uddi-org:api_v3">
