Manage Vendor Certification Priorities

If the metric family for a device supports more than one vendor certification, the vendor certification with the highest priority is selected as the backing vendor certification. New custom vendor certifications are automatically added to the bottom of the priority list for the specified metric family. If necessary, modify the priority list and move the vendor certification to a higher priority. To use more than one vendor certification for the same device, group vendor certification priorities.

Prioritize the Vendor Certification Within the Metric Family
When you change the priority of the vendor certifications for a metric family, the metric family is updated on all affected devices. An event is generated on the metric family, indicating that the vendor certification priority on the metric family has changed. If the backing vendor certification changes on a device, an event is generated on the device. The event indicates that a vendor certification has changed. A second event is also generated, indicating the specific changes.
To take advantage of any new vendor certifications that are part of an installation upgrade, manually change the vendor certification priorities. For example, F5 CPU vendor certifications are modeled as normal CPUs but are not discovered because F5 also supports Host Resources. After an upgrade, the Host Resources CPU priority entry will be higher than the F5 entries appended to the end of the priority list. To discover F5 CPU devices and components, update the vendor certification priority for the CPU metric family. A fresh installation does not have this issue.
 
Follow these steps:
 
  1. Log in to the UI, and navigate to the 
    Data Aggregator
     data source.
  2. Click 
    Monitoring Configuration
    Metric Families
  3. Select a metric family, and click the 
    Vendor Certification Priorities
     tab.
    The list of prioritized vendor certifications appears.
  4. Click 
    Manage
    .
  5. Arrange the priority order as necessary, and click 
    Save
    .
  6. The metric family uses the new priority to determine which vendor certification to use for monitored devices.
Group Vendor Certification Priorities
Grouping vendor certification priorities lets you use more than one vendor certification for the same device. A single vendor certification priority can belong to as many priority groups as necessary for your application. When a device is discovered, all vendor certifications in the priority group are supported on the device.
 Do not update PriorityGroup and change the order of the vendor certifications in the same REST call. Changing both simultaneously may disrupt automatic rediscovery. For more information, see Automatic Rediscovery Does Not Run After Updating Vendor Group Priority.
To group vendor certification priorities, use the REST Web Services. You cannot group vendor certification priorities using the UI.
 
Follow these steps:
 
  1. Run a GET operation on the following REST URL:
    http://
    da_host
    :8581/rest/vendorpriorities/
    The REST call returns a list of all the vendor certification priorities.
  2. Determine the ID of your metric family in the list of vendor certification priorities.
  3. Run a GET operation on the following REST URL:
    http://
    da_host
    :8581/rest/vendorpriorities/
    ID
    The XML of the vendor certification priority that you want to modify is retrieved.
  4. To add a vendor certification priority to a group, add the 
    <PriorityGroup>
     tag to the vendor certification.
    Example:
    In this example, the vendor certification priority is added to the group entitled "F5".
    <CertificationOrder>
    <CollectionID>167</CollectionID>
    <VendorCertID>{http://im.ca.com/certifications/snmp}F5BigipMultihostCpu</VendorCertID>
    <PriorityGroup>F5</PriorityGroup>
    </CertificationOrder>
     Proper XML for the
     <VendorCertID>
     tag is written on a single line, and excludes spaces and carriage returns. Failure to follow this guideline causes the vendor certification priority to fail.
     To enabled recommended priority groups, replace the 
    <RecommendedPrioritiyGroup>
     tag with the 
    <PriorityGroup>
     tag.
  5. (Optional) To add a single vendor certification priority to multiple groups, separate the group names using commas.
    Example:
    <PriorityGroup>F5, Huawei</PriorityGroup>
     
  6. Remove the 
    <ID>
     and 
    <MetricFamilyID>
     tags from the vendor certification priority XML.
  7. Run a PUT REST call on the following URL to import the new XML file:
    http://
    da_host
    :8581/rest/vendorpriorities/
    ID
     
    ID
    Specifies the ID of the vendor certification priority.
    CA Performance Management
     rediscovers all devices that support the metric family.
Verify Vendor Certification Priority Grouping
Verify that the vendor certification priorities are grouped as necessary.
 
Follow these steps:
 
  1. Log in to the UI and navigate to the Data Aggregator data source.
  2. Click 
    Monitored Inventory
    Monitored Devices
    .
  3. Select a device from the Tree View.
  4. Click the 
    Polled Metric Families
     tab in the pane on the right.
    The vendor certifications that you grouped under the corresponding metric families appear on multiple rows in the 
    Vendor Cert
     column.
