NetXMS Support Forum

Hello,

Quoting from the manual:

"NetXMS has subagents that allow to monitor hypervisors. " But it doesnt say which hypervisors.

I see some configs for ESX, but what about Xen, HyperV, QEMU etc? Proxmox?

Can I / How Can I monitor Proxmox VE / QEMU with this subagent?

Thank you,

Alex

we use libvirt: https://libvirt.org/drivers.html

Thank you,

I have now discovered that unfortunately proxmox does not use libvirt and installing it on the host is risky as it can clash with the underlying qemu lxc tech that proxmox uses. Proxmox strongly advises against doing this.

So at this point we can say that NetXMS does NOT support Proxmox monitoring using the documented Hypervisor monitoring methods.

It may be possible to do via the proxmox API which is the proxmox approved method.

The netxms agent does monitor the usual proxmox host details just fine, but I am looking to collect the metrics about the vms / containers etc.

The documentation should be updated to reflect this, and also note that there seems to be a separate subagent package for Xen.

For completeness here is a config that I have tried, on the pve host:

apt install netxms-agent-vmgr
 apt install netxms-agent-vmgr
The following packages were automatically installed and are no longer required:
  libsnmp-base  libsnmp40t64  proxmox-kernel-6.17.2-2-pve-signed
Use 'apt autoremove' to remove them.

  netxms-agent-vmgr

Yes I see that the libvirt process is not running but I am reluctant to run it due to the various comments out there about libvirt issues with proxmox
