The diagnostic code was warning ALL deployments using /run/pulse-sensor-proxy
socket path to "remove and re-add" their configuration to use /mnt/pulse-proxy
instead. This was incorrect for Docker deployments where /run is the correct
and documented mount path (see docker-compose.yml line 15).
The warning was only meant for LXC containers where the managed mount at
/mnt/pulse-proxy is preferred over a legacy hand-crafted /run mount.
Fix: Only show the warning in non-Docker environments (check PULSE_DOCKER env).
Docker deployments correctly use /run/pulse-sensor-proxy per compose file.
Impact: Docker users were seeing confusing diagnostic warnings telling them
to reconfigure a correct setup.
Related to #630
Proxmox 8.3+ changed the VM status API to return the `agent` field as an
object ({"enabled":1,"available":1}) instead of an integer (0 or 1). This
caused Pulse to incorrectly treat VMs as having no guest agent, resulting
in missing disk usage data (disk:-1) even when the guest agent was running
and functional.
The issue manifested as:
- VMs showing "Guest details unavailable" or missing disk data
- Pulse logs showing no "Guest agent enabled, querying filesystem info" messages
- `pvesh get /nodes/<node>/qemu/<vmid>/agent/get-fsinfo` working correctly
from the command line, confirming the agent was functional
Root cause:
The VMStatus struct defined `Agent` as an int field. When Proxmox 8.3+ sent
the new object format, JSON unmarshaling silently left the field at zero,
causing Pulse to skip all guest agent queries.
Changes:
- Created VMAgentField type with custom UnmarshalJSON to handle both formats:
* Legacy (Proxmox <8.3): integer (0 or 1)
* Modern (Proxmox 8.3+): object {"enabled":N,"available":N}
- Updated VMStatus.Agent from `int` to `VMAgentField`
- Updated all references to `detailedStatus.Agent` to use `.Agent.Value`
- The unmarshaler prioritizes the "available" field over "enabled" to ensure
we only query when the agent is actually responding
This fix maintains backward compatibility with older Proxmox versions while
supporting the new format introduced in Proxmox 8.3+.
Improvements to pulse-sensor-proxy:
- Fix cluster discovery to use pvecm status for IP addresses instead of node names
- Add standalone node support for non-clustered Proxmox hosts
- Enhanced SSH key push with detailed logging, success/failure tracking, and error reporting
- Add --pulse-server flag to installer for custom Pulse URLs
- Configure www-data group membership for Proxmox IPC access
UI and API cleanup:
- Remove unused "Ensure cluster keys" button from Settings
- Remove /api/diagnostics/temperature-proxy/ensure-cluster-keys endpoint
- Remove EnsureClusterKeys method from tempproxy client
The setup script already handles SSH key distribution during initial configuration,
making the manual refresh button redundant.
