The mixed-hypervisor reality
Why Australian infrastructure teams are running ESXi and Proxmox together
Following Broadcom’s changes to VMware licensing, very few mid-market Australian businesses cut over 100% of their hosts overnight. Most run a dual estate for 12 to 36 months: existing VMware ESXi hosts stay in production while branch sites, DR nodes or new workloads land on Proxmox VE backed by ZFS storage pools and TrueNAS appliances.
Traditional Windows-centric RMM tools struggle with both: they either ignore hypervisor hardware health altogether or charge per-host SNMP add-on fees on top of every guest VM.
What BE Hub watches
Host hardware, datastore trendlines, ZFS pools and guest VMs in one view
- Agentless VMware ESXi host monitoring: Tracks host CPU, memory ballooning, datastore free space and 90-day fill-date forecasts, hardware sensor health, NIC link state and running VM states (ESXi platform details).
- Deep Proxmox VE & ZFS pool health: Monitors
zpool statusstate (ONLINE, DEGRADED, FAULTED), scrub age and checksum/read/write errors, ARC usage, snapshot growth, and per-disk SMART health (ZFS & Proxmox details). - 90-day datastore & pool exhaustion forecasting: Instead of paging at 3:00 am when a thin-provisioned datastore or ZFS pool hits 99%, BE Hub projects the exact date a volume will fill based on its 90-day growth slope (how disk-full forecasting works).
- Unlimited hosts and guest VMs for $105/technician/month: Because BE Hub is priced per technician in Australian dollars—not per host or per VM—monitoring both the hypervisor and every Windows or Linux guest inside it adds $0 to your monthly bill.
Side-by-side
What is checked across VMware ESXi and Proxmox / ZFS
| Check category | VMware ESXi host | Proxmox VE / TrueNAS ZFS host |
|---|---|---|
| Storage health & capacity | Datastore usage, thin-provisioning growth & 90-day fill forecast | ZFS pool state, scrub errors, dataset quotas & 90-day fill forecast |
| Physical disk & hardware telemetry | Host hardware sensors, RAID controller & PSU status | SMART attributes, NVMe/SAS wear & ZFS vdev error counters |
| Guest VM correlation | Maps guest Windows/Linux alerts to the underlying ESXi host | Maps KVM/LXC guest alerts to the underlying Proxmox node |
| AI root-cause investigation | Correlates datastore latency with guest disk queue spikes | Correlates ZFS scrub/snapshot I/O with guest performance alerts |
| Cost per host or guest VM | $0 per host / VM ($105/tech/mo unlimited) | $0 per host / VM ($105/tech/mo unlimited) |
Questions infrastructure engineers ask
- Do we pay extra to monitor both the ESXi or Proxmox host and the guest VMs inside it?
- No. BE Hub Hosted is A$105 per technician per month ex-GST with unlimited enrolled machines, hypervisors, storage appliances and guest VMs.
- How does BE Hub monitor VMware ESXi without installing a VIB on the host?
- BE Hub monitors VMware ESXi agentlessly using read-only credentials from a lightweight collector, polling host hardware, datastores and VM state safely without modifying the ESXi image.
- Does BE Hub alert if a ZFS scrub has not run or a pool degrades?
- Yes. BE Hub tracks ZFS pool health, vdev read/write/checksum counters and scrub age on Proxmox, TrueNAS and Linux ZFS hosts, raising an immediate alert the moment a disk degrades.
