Describe the bug
Since we upgraded from 21.11 version to harvest version 22.02.0-4 (commit 9484df6) (build date 2022-02-15T09:09:54-0500) linux/amd64 we can't see information in the grafana dashboards defined but If we created new customized dashboards we have the information on the database. I think that our harvest is missing some important information which it is used for built the variables in grafana's dashboards. I was thinking that the problem be related with the current version of grafana 8.3.4 but this is not the problem since I tried with grafana 7 and the problem continues.

Environment
Provide accurate information about the environment to help us reproduce the issue.

• Harvest version: 22.02.0-4 (commit 9484df6) (build date 2022-02-15T09:09:54-0500) linux/amd64
• Command line arguments used: [e.g. bin/harvest start --config=foo.yml --collectors Zapi]
• OS: Red Hat Enterprise Linux release 8.2 (Ootpa)
• Install method: yum
• ONTAP Version: 9.7

Expected behavior
We should able to see the dashboards in grafana like we do in previous versions.

Actual behavior
We can't find the metrics node_labels in our metrics (counter, objetc), this parameter is used for built the variable "Datacenter" in many dashboards. This is an example but this happens with other metrics, for example checking the ### NetApp Detail: Cluster we don't find node_new_status too in the metrics browser.
