Proxmox Monitoring That Goes Beyond Basic Host Metrics

A Proxmox node can show 40% CPU while individual VMs fight for resources. Get visibility into the hypervisor layer, VMs, storage health, and resource allocation with 5-second precision.

Hypervisor Metrics

CPU, memory, swap, network throughput, and disk I/O on your Proxmox node with 5-second precision.

VM Resource Tracking

Monitor per-VM resource consumption. Identify over-provisioned or under-provisioned VMs and pinpoint contention issues.

Storage & RAID Health

Track disk space, I/O performance, and RAID health. S.M.A.R.T. monitoring catches failing drives before you lose data.

Process-Level Visibility

See which processes on the Proxmox host consume the most resources. Identify runaway QEMU processes, unexpected CPU consumers, or memory-hungry services competing with your VMs.

Intelligent Alerting

Set thresholds for any metric at the host or VM level. Get notified when CPU steal time spikes, when a VM's memory approaches its limit, or when storage latency degrades.

Alerts go where your team works: email, Slack, Telegram, Discord, Pushover, or webhooks.

Common Proxmox Monitoring Scenarios

Homelab with 3-5 VMs

Monitor host resources and ensure no single VM monopolizes CPU or RAM. Get disk space alerts before your local storage fills up.

Small hosting provider

Track resource allocation across customer VMs. Spot noisy neighbors, monitor storage pool health, and ensure SLA compliance with historical data.

Development infrastructure

Watch CI/CD runner VMs, staging environments, and database VMs. Catch performance regressions before they hit production.

Frequently Asked Questions

Does the agent run on the Proxmox host or inside VMs?
Install the agent on the Proxmox host to get hypervisor-level metrics, storage monitoring, and process visibility. You can also install it inside individual VMs for guest-level metrics.
Will it affect VM performance?
The agent is lightweight and designed for production environments. Its resource footprint is negligible compared to the workloads running on a typical Proxmox node.
Does it monitor Proxmox clusters?
Install the agent on each node in your cluster. The Fivenines dashboard gives you a unified view of all nodes and their VMs.
What storage backends are supported?
The agent monitors disk I/O and space usage regardless of the storage backend - local storage, ZFS, LVM, NFS, or Ceph. RAID and S.M.A.R.T. monitoring works with hardware that supports these standards.
Can I monitor Proxmox Backup Server?
The agent can be installed on your PBS host to track its resource usage and storage consumption. Monitoring PBS backup job success/failure is on the roadmap.
