The network audit grades three networks by listening to them: the crew network, the lighting network, and the audio and media network. It doesn't transmit anything, except the one deep probe that an admin can run. The steps for a site visit are in Audit the network.

Network audit

Opens the audit. Anyone on the crew can open it.

The header

Overall grade

The worst grade among the networks being watched. A network that isn't watched doesn't lower it.

Grade	Means
Good for A/V	Nothing to fix.
Usable — fixes below	It works, but at least one finding needs attention.
Not suitable right now	At least one finding is a fault.
Not watched	The box isn't listening to that network. This isn't a fault.

Report age

How old the report on screen is: just now, N min ago or N hours ago. The pane refreshes every 10 seconds while it's open, and straight away when you come back to the tab. If a refresh fails, Waiting for the box: … appears and the report you already have stays on screen, with its age showing how old it is.

Saves one self-contained file with the grades, findings, charts, event log and the list of what the probe sent. It opens anywhere without internet and prints cleanly. Where the device can't download files, the note suggests sharing the audit to a channel instead.

The network cards

Each card has a grade and a list of findings. Every finding shows the following:

a state: ● Working, ◐ Limited, ○ Fault or · For information
a sentence saying what was found
where the finding isn't fine, a fix in plain words
where there's history, a small chart of the last hour

The findings are judged over the last 15 minutes, not from a single reading.

Crew network

Needs nothing set up: crew phones report their round trip to the box once a minute.

Finding	What it says
Crew devices	How many connections are open and how many crew are online.
Wi-Fi round trip	The phones' average time to the box. Up to 150 ms is working, up to 400 ms is limited, and anything slower is a fault. The fix points at the Wi-Fi, not the box.
Internet uplink, Venue DNS	Only after a deep probe.

Lighting network

Needs the box listening for sACN or Art-Net. Set this in Admin → This box → Networks → Lighting network listening and restart the box. Until then the card is Not watched, with the finding Not listening to Art-Net or sACN.

Finding	What it says
Lighting data	How many universes are live, or Listening, but nothing is arriving.
Universe N frame loss	Frames lost over 15 minutes.
Universe N refresh rate	The stream is sagging below the rate it has reached before.
Two sources on one universe	Two consoles are fighting over a universe. If the conflict has ended, it's reported for information.
Stage frozen	The desk is still sending, but a universe is stuck on its last synchronised look because the sync stream died.
Multicast dies on a cycle	Outages at a regular few-minute rhythm, which is the usual sign of IGMP snooping without a querier.
Art-Net inventory	Only after a deep probe.

Audio & media network

Needs the box started with CREWBOX_WATCH=1 (and CREWBOX_WATCH_IFACE to pick the adapter), with the box connected to the media network. Until then the card says Not watching the media network (PTP clock, Dante/NDI rosters).

Finding	What it says
PTP clock	Whether the clock is steady, how often the grandmaster has changed in the last 10 minutes, or No PTP clock heard.
Clocks announcing	More than one clock is announcing at once, which means an election is running.
Mixed PTP generations	PTPv1 (classic Dante) and PTPv2 are on the same wire.
Devices dropping	Devices left the network in the last hour.
Media roster	Counts of Dante devices, NDI sources and AES67 streams.

The event strip

A 24-hour timeline under the cards. Red marks are faults: a lighting outage, a frozen sync, a watched network going dark, or a device dropping off. Amber marks are changes. The latest eight are listed below the strip with their times, and the rest are in the exported report. A quiet network says so.

Deep probe

A single sweep that checks the internet uplink and the venue's DNS, sends one Art-Net poll and one mDNS query, and then stops. It's the only thing in the module that transmits.

Run deep probe

Shown to anyone with the admin panel unlocked on their device. Other devices see An admin can run one from their device. The button reads Probing… while it runs, and a second probe can't start while one is running.

Results

Last run N min ago by …, followed by each check's result and fix. Under each one, a sent: line gives exactly what went on the wire, so a strict venue can check it against a packet capture. The uplink, DNS and Art-Net results also show up as findings on the cards.
