Hi all,

I have several clusters added to proxmox data manager and none except the largest have a problem displaying graphs and data. All clusters are on the same version Proxmox Envinronmnet 8.4.1. Unfortunately there is some issue in PDM and what I see in metric-collection-state.json is only error code 596.

cat /var/lib/proxmox-datacenter-manager/metric-collection-state.json
{
"remote-status": {
"alfa-cluster": {
"most-recent-datapoint": 0,
"last-collection": null,
"error": "api error (status = 596: )"
},

I have tried to create separate token to get metrics to PDM from this cluster but all options has failed. I have no problem with any other cluster on the same version of proxmox environment. Does anyone know what could be causing it?

Can you please check the journal and pveproxy access log in /var/log/pveproxy/access.log on the PVE cluster for any more hints?
Focus on the node that is listed first in the PDM remote config entry.

Roughly how many guests are on that cluster?

You're sure that fingerprint/cert are correctly configured for the remote?
