Hypervisor Resource overview using API

[fossaaen]

Hi,

I have a problem I hope someone might be able to point me in the correct direction to solve.

My issue:
I want to list out memory used and installed physical memory for each hypervisor in a cluster, using http API call.

When doing a CLI, the result is presented as I want, like:

This shows physical memory (maxmem) and used memory (mem) for each hypervisor.

When trying to do the same from the http api call, I would expect to get same output, but only get very partial details compared to CLI, like:
Command used on the bottom line, and two hypervisor example outputs 'snipped in'. Why is the info using http so reduced compared to CLI, or am I missing something to get the same details level using http?

I'd assume you have to pass it some of the optional parameters described in https://pve.proxmox.com/pve-docs/api-viewer/#/cluster/resources
DIdn't test it myself though

Hi, thank you for responding.

How would you format the command to include one of the optional parameters then, like 'maxmem' ? Tried several things whithout getting a working command

my bad, the optional parameters are return value.

anyways, your code works for me. with your command curl -k -b $ticket -X GET "https://localhost:8006/api2/json/cluster/resources | jq -r '.data[] | select(.type | contains("node"))'" I get the output

{
  "node": "dev200",
  "cpu": 0.00606196452336456,
  "uptime": 7223,
  "type": "node",
  "mem": 1321598976,
  "maxdisk": 67799756800,
  "status": "online",
  "level": "",
  "disk": 45155565568,
  "maxcpu": 8,
  "id": "node/dev200",
  "maxmem": 16675291136
}

Update; problem solved

It still only reported 5 of those values when running in our environment, but after some digging I found the cause:

The user used to authenticate towards proxmox was missing one essential privilige: Sys.Audit
Adding this fixed the problem and all values reported as expected.

The doc on https://pve.proxmox.com/pve-docs/api-viewer/#/cluster/resources says:
Required permissions: Accessible by all authenticated users.

Maybe doc should be updated with correct requirements ?

Thank you for your assist!
