Get free resources for nomad cluster or nodes

Is it possible to get free memory/CPU for the cluster or at least for all nodes through API? I can see this information in nomad node status <node-name-or-id> but I can’t in /nodes endpoint.

I can see storage data:

                '': '120788234240',
                '': '128837464064',

but for memory only total:

                'memory.totalbytes': '32667799552',

and reserved resources has zero values:

 'ReservedResources': {'Cpu': {'CpuShares': 0, 'ReservedCpuCores': None},
                       'Disk': {'DiskMB': 0},
                       'Memory': {'MemoryMB': 0},
                       'Networks': {'ReservedHostPorts': ''}},

You could try the v1/metrics endpoint of the API. I think could get total amount of memory, current usage, allocated memory and much more.

Let us know if this solves your use case.

I’m already using the metrics approach, but is there really no other way? It seems that the /node endpoint has an allocated field, but it’s returning no data - all the fields have zero value"… Also, we have clusters with ~20 nodes and we need to visit EACH endpoint for EACH node.
