Linux Benchmark Library

Highlights

• Layered architecture: runner, controller, app, UI, analytics.
• Workload plugins via entry points and user plugin directory.
• Remote orchestration with Ansible and run journaling.
• Organized outputs: results, reports, and exports per run and host.

Quickstart (CLI)

lb config init -i
lb plugin enable stress_ng
lb run --remote --run-id demo-run

Quickstart (GUI)

# Avvia l'interfaccia grafica moderna
lb-gui

Dev-only provisioning (requires .lb_dev_cli or LB_ENABLE_TEST_CLI=1):

LB_ENABLE_TEST_CLI=1 lb run --docker --run-id demo-docker

Quickstart (Python)

from lb_controller.api import (
    BenchmarkConfig,
    BenchmarkController,
    RemoteExecutionConfig,
    RemoteHostConfig,
)

config = BenchmarkConfig(
    repetitions=2,
    remote_hosts=[
        RemoteHostConfig(name="node1", address="192.168.1.10", user="ubuntu")
    ],
    remote_execution=RemoteExecutionConfig(enabled=True),
)

controller = BenchmarkController(config)
summary = controller.run(["stress_ng"], run_id="demo-run")
print(summary.per_host_output)

Installation

uv venv
uv pip install -e .  # runner only

Extras:

uv pip install -e ".[ui]"          # CLI/TUI
uv pip install -e ".[gui]"         # Graphical UI (Qt)
uv pip install -e ".[controller]"  # Ansible + analytics
uv pip install -e ".[ui,gui,controller]"  # Full installation
uv pip install -e ".[docs]"        # mkdocs

Development setup uses the dev dependency group (pytest, ruff, basedpyright, bandit, pre-commit, import-linter) rather than an extra:

uv sync --all-extras
uv run pre-commit install

Switch dependency sets:

bash scripts/switch_mode.sh base
bash scripts/switch_mode.sh controller
bash scripts/switch_mode.sh headless
bash scripts/switch_mode.sh dev

Logging policy

• Configure logging via lb_common.api.configure_logging() in your entrypoint.
• lb_ui configures logging automatically; lb_runner and lb_controller do not.
• Keep stdout clean for LB_EVENT streaming when integrating custom UIs.
