Limit which instances are collected

Discussed in #867

We have a use case where we are collecting file lock statistics for a specific vserver. I have built the following template to collect lock stats:

name: Locks
query: lock-get-iter
object: lock

collect_only_labels: true

counters:
lock-info:
- ^node
- ^volume
- ^vserver
- ^path
- ^^lockid
- ^client-address => client_ip
- ^smb-open-type => smb_open_type

export_options:
instance_keys:
- lockid
instance_labels:
- vserver
- volume
- node
- path
- client_ip
- smb_open_type

The above template collects all the locks in the cluster, and there may be hundreds of thousands of them.

Is there any way to limit which instances are collected, to reduce load on cluster? For example, limit collection to only a specific vserver or volume?

Thanks.

@luddite516 as of Harvest 24.02, filtering is supported by the Rest and ZapiPerf collectors. We still don't have filtering for Zapi, would moving to Rest work you?

ONTAP added api/protocols/locks in ONTAP 9.10.0, REST private CLI for 9.6+ may also work for you if you're unable to upgrade.

Yes, I believe we could move to REST. We are going to have to get there eventually.

@luddite516 See if the lock templates for Zapi and Rest are helpful. These templates only provide the count of locks at the node, svm, lif, and volume levels. They are designed to avoid collecting thousands of lock instances, as requested in this issue.
