Node metadata not always returned

Unresolved

Description

When generating a single panel based on a multi-value variable for a Performance DS, the nodeToLabel() formatter only applies to some of the returned nodes so that some nodes have a nodelabel and others have a FID:FID. Looking at the query inspector, the response metadata for nodes is missing instances for the FIS:FID nodes. It appears that these nodes do not have SNMP attributes collected, though the expectation is that the node label from inventory should still be returned.

Tested against Horizon 31. Replicated on both Helm 8.0.4 and Plugin v9.0.4, though there was a difference in which nodes did and did not return metadata.

Can confirm that the Measurements API does not send back node metadata for items that it could not find resources for. Looking into a server-side fix that would return node metadata for any requested resources.

could you send me an example response which has response metadata for some nodes but not others? Trying to determine whether this is a server-side or client-side issue, or if the client-side can have a fallback if server does not include the label info in the metadata.
