Cockpit Benchmark

A Visual Storage Benchmark Utility for Cockpit that lets you run quick storage benchmarks with fio, visualize results, and export a shareable report. It’s designed for day-to-day validation and sanity checks on test paths (single disk, RAID, pools, mounts, etc.) directly from your browser.

Features

• Three benchmark modes

  • Max Throughput (1M record size, bandwidth-oriented)

  • Max IOPS (4k record size, ops-oriented)

  • Performance Spectrum (4k → 1M sweep)

• Workloads covered: sequential Reads/Writes and random Reads/Writes

• Progress feedback with live percentage and status text

• Interactive bar chart: toggle between IOPS and Bandwidth

• Downloadable reports in XLSX, CSV, or ODS

• Input validation for runtime, file size, and test path existence

• Least-privilege execution via Cockpit’s privilege escalation when needed

Installation

• install with dnf or apt
  • dnf install cockpit-benchmark

Usage

• Open Cockpit → Benchmarks.

• Choose Benchmark Type:

  • Max Throughput (1M block size, Bandwidth chart default)

  • Max IOPS (4k block size, IOPS chart default)

  • Performance Spectrum (4k → 1M sweep)

• Set parameters:

  • File Size and Unit (MiB/GiB)

  • IO Depth (1–128)

  • Runtime (seconds; excludes 5-second ramp time)

  • Test Path (must exist; e.g., /mnt/hdd or a dataset/mount)

• Click Launch. A progress bar displays status until completion.

• Toggle Chart Output between IOPS and Bandwidth as needed.

• Click Download Report to save results as XLSX, CSV, or ODS.
