fuse host get

Show a host's details

fuse host get <id>

No flags beyond the globals. Prints the host’s full detail: URL, region, backend, arch, firecracker release, labels, state, capacity vs. allocated (CPUs, RAM, storage, VM count, and GPUs or MIG profiles if the host has any), last seen time, and created/updated timestamps.

A GPU host adds a gpus row, and a MIG host a mig row listing each declared profile’s allocation, sorted by profile name:

$ fuse host get gpu-1

The gpus row appears only when the host has whole-device GPU capacity, and the mig row only when it declared MIG profiles; a host offering just one of the two shows just that row. Per-device inventory (each GPU’s UUID, model, PCI address, memory, driver version, and MIG mode) is not rendered in the table, read it with -o json.

firecracker is the release the host agent reported at registration, with the release its fc-agent.py pins in parentheses when the two differ (for example v1.16.0 (pinned v1.17.0)). It is - on a qemu host, an agent too old to report it, or a host registered before the orchestrator stored it.

last seen is set once at registration and is never refreshed afterward, it is not a liveness signal, don’t use it to detect a dead host agent.
