About this package

Real-time terminal dashboard for Frigate NVR/CCTV servers

frigate-top

A real-time, interactive terminal dashboard for Frigate NVR/CCTV hosts — htop for your Frigate box. Stdlib-only Python, one file, no required dependencies.

frigate-top dashboard

It shows host-level metrics (CPU, memory, disk I/O, network I/O + errors, NVIDIA GPU, CPU iowait, load) and Frigate-specific metrics (skipped frames, detector inference time, detection FPS, camera FPS, online/offline cameras, estimated supported cameras) across a grid of block-bar graphs (one GPU set per detected GPU). Each graph fills the full width over the configured timeframe, carries a -span … now time axis, colours its fill and current value green/amber/red by warn/crit thresholds, and marks the newest sample with a bright endpoint.

What it does

  • Draws a live, auto-refreshing dashboard grouped into SYSTEM / NETWORK / FRIGATE bands with colour-coded graph borders (blue = system, yellow = network, orange = Frigate).
  • Shows a header table grouped into identity (hostname, uptime, OS, kernel), hardware (CPU, memory, GPU model + driver), Frigate (version, camera counts, supported-camera estimate, detector), and streams/storage (resolution, retention, interface, disk) — plus a status line of active warnings.
  • Summarises tracked-object activity for the selected timeframe in the header (Detections 1m 4 person 2 vehicle 1 animal 2 face 1 plate), pulled from /api/events — a fixed category breakdown (person / vehicle / animal / recognised face / recognised plate, plus other) so the structure is visible even at zero. The API is polled at most every few seconds and cached.
  • Collapsible sections — press s / w / f to fold the System / Network / Frigate groups; System and Network start collapsed so everything fits smaller terminals. Handles live terminal resizing without dropping graphs.
  • Detects multiple GPUs and draws a labelled GPU0 / GPU1 … util/mem/temp set for each.
  • Graphs Frigate skipped frames and NET errors in red on any nonzero value — these should always be zero, so they catch the eye immediately.
  • Renders block-bar graphs by default (--braille for dense Braille area charts, --ascii for plain ASCII). Fills always span the full width and scroll left over the true timeframe; the x-axis reports how much history is currently shown.
  • Encodes health in colour: bars and the title value turn amber past the warn threshold and red past crit, with a dashed guide line at each threshold and a ▲/▼/→ trend arrow versus the window start.
  • Marks absent sensors (no GPU, no Frigate) with a dimmed no sensor panel instead of a misleading flat line.
  • Estimates how many cameras the detector(s) can keep up with — a throughput bound (detector inferences/sec × headroom ÷ configured detect fps), which is the real limit on a Frigate box. It is motion-independent (uses the configured detect fps, not the noisy live rate); a single Coral at 5 fps works out to ~18 cameras. Tune the safety margin with --detector-headroom (default 0.75).
  • Auto-detects the Frigate API at common ports (5000, 8971, 80, 443) and protocols (HTTP/HTTPS) (override with --frigate-url); tracks disk and the busiest network interface (pin with --disk / --net-iface).
  • Lets you switch history timeframe on the fly (1, 5, p for 15m, t for custom) and export samples to CSV (--csv).

Install

frigate-top is a single stdlib-only module — install it however suits you.

From the Forgejo package registry (pip):

pip install --index-url https://git.jdneer.com/api/packages/jd/pypi/simple/ frigate-top
# optional: robust YAML config parsing (a regex fallback is used without it)
pip install --index-url https://git.jdneer.com/api/packages/jd/pypi/simple/ 'frigate-top[yaml]'
frigate-top

From source:

git clone https://git.jdneer.com/jd/frigate-top.git
cd frigate-top
pip install .          # or: pip install '.[yaml]'
frigate-top

Single file (no install): copy frigate_top.py to the host and run it — it needs only Python 3.7+.

scp frigate_top.py user@frigate-host:/usr/local/bin/frigate-top   # optional: drop it on PATH
python3 frigate_top.py

Usage

Run frigate-top (installed) or python3 frigate_top.py (single file).

Controls (keyboard):

  • m — toggle memory graph between percentage and bytes (used / cached / free)
  • n — toggle network graphs between Mbps and MB/s
  • s / w / f — collapse or expand the System / Network / Frigate sections (System and Network start collapsed)
  • 1 / 5 / p — set history to 1 / 5 / 15 minutes
  • t — set a custom history timeframe (in minutes)
  • q — quit

Examples:

# Default 1-minute history, 1-second refresh
frigate-top

# 10-minute history
frigate-top --timeframe 10

# Point to a Frigate API and config
frigate-top --frigate-url http://localhost:5000 --config /config/config.yml

# Pin a specific network interface / disk device
frigate-top --net-iface eth0 --disk nvme0n1

# Write samples to CSV
frigate-top --csv /tmp/frigate-top.csv

# Dense Braille area charts, or plain ASCII with no colour
frigate-top --braille
frigate-top --ascii --no-color

# One-off snapshot for cron or health checks (works headless)
frigate-top --snapshot

Requirements

  • Python 3.7+ (Linux — reads /proc and /sys)
  • No required dependencies. frigate-top runs on the standard library alone.
  • Optional, detected at runtime:
    • PyYAML (frigate-top[yaml]) — richer Frigate config parsing; a minimal regex fallback is used without it
    • nvidia-smi — NVIDIA GPU stats
    • docker or podman — Frigate container status
    • A reachable Frigate API — camera/detector stats and the detections summary

Configuration

All options can be set via command-line arguments or environment variables.

Files

File Description
frigate_top.py The dashboard — a single stdlib-only module
pyproject.toml Package metadata (version read from __version__)
requirements.in / requirements.txt Optional pinned + hash-verified PyYAML (see below)
VERSION.md / CHANGELOG.md Versioning and release notes
LICENSE / NOTICE / DISCLAIMER.md Apache-2.0 licence and terms

Optional supply-chain hardening

PyYAML is optional. If you want it hash-verified, requirements.txt pins it with SHA-256 hashes:

pip install --require-hashes -r requirements.txt

Regenerate after changing requirements.in:

pip install pip-tools && pip-compile --generate-hashes requirements.in -o requirements.txt

Versioning

frigate-top follows Semantic Versioning. The version lives once in frigate_top.py as __version__ and flows to the header title and the built package — see VERSION.md for the release process and CHANGELOG.md for history.

Notes

  • If the terminal is too small or not a TTY, use --snapshot for a one-off reading.
  • The first sample is used as a baseline and is not shown in the graphs, so deltas are meaningful.
  • Frigate config auto-detection tries /config/config.yml, /config/config.yaml, /etc/frigate/config.yml, /opt/frigate/config/config.yml, and ~/frigate/config/config.yml.
  • MQTT broker monitoring is intentionally not included because the broker is optional and containerized; the Frigate API provides the same health signals.
  • Security posture: the tool is read-only — it shells out only to fixed commands (nvidia-smi, docker/podman ps, df) with no shell or user-interpolated arguments, parses YAML with safe_load, and writes its optional --debug log to a per-user directory ($XDG_RUNTIME_DIR) opened with O_NOFOLLOW. TLS certificates are verified for remote HTTPS Frigate instances; verification is relaxed only for loopback hosts (where self-signed certs are the norm) or when --insecure is passed.
