perf-object-get-instances for cmode

I'm trying to get the instances for an object using the API.


I was able to run "perf-object-counter-list-info" to retrieve the list of all the objects and now I was hoping to run get-instances to get the instances of each object, but in cmode, the instance-uuid OR the instance name is required.

How do I retrieve ALL the instances or the instance-uuid's so I can successfully run this API?
