Through libvirt, nothing in the guests

The agent on the hypervisor reads each VM through libvirt. Add its user to the libvirt group and every guest shows up, with nothing to install inside the VMs.

  • CPU and memory used by each VM
  • Disk read and write throughput
  • Network traffic in and out
  • Next to the hypervisor’s own CPU, memory and disk

Every guest on every hypervisor

Find the VM that is eating the host, before its neighbours notice.

Every VM

All the guests libvirt knows about, on each hypervisor.

CPU and memory

How much each VM uses, so the noisy neighbour stands out.

Disk throughput

Read and write throughput for each VM.

Network traffic

Bytes in and out for each VM.

No sudo needed

The agent only needs to be in the libvirt group.

24 months of history

Every VM metric is kept for 24 months.
