Hi Scott,
Do you have a specific Metric Family and related Vendor Cert you're looking to implement this for?
What CAPM release are you running that you're looking implement this change in?
With the above simple question asked, my initial response would be to reference the documentation around the Metric Family and Vendor Cert extension functionality. If not familiar with it, its nice because it allows you to extend the existng factory certs with the small subset of edits you're looking to make, rather than having to rewrite the entire cert from scratch for a small change.
Note the different URLs in the docs for creating a full custom cert vs extending an existing (out of the box or full custom) cert.
Specify one of the following URLs:
- Custom Metric Family: http://da_hostname:8581/typecatalog/metricfamilies
- Extend Metric Family:http://da_hostname:8581/typecatalog/metricfamilies/extension
Metric Family creation/editing/extension:
Create or Extend Metric Families - CA Performance Management - 2.6.0 - CA Technologies Documentation
Vendor Certification creation/editing/extension:
Create or Extend Vendor Certifications - CA Performance Management - 2.6.0 - CA Technologies Documentation
Hope that helps.
Mike
