What metrics matter most during an incident?

Latency trend, jitter, loss percentage, and a clear up/down for the affected service. Single-sample metrics lie — show a 1–5 minute trend so the room sees direction, not noise.

How big should the screen be?

Big enough that the on-call engineer at the back of the room can read the loss percentage. If you're squinting, the layout failed.

NOC Mode

A big-screen dashboard for latency, jitter, loss, throughput, and service health during incidents.

What this is

NOC Mode is a heads-up display you can throw on a wall TV during change windows or incidents. It surfaces a small set of high-signal metrics — latency, jitter, loss, throughput, status — so the room agrees on reality without arguing about which tab to open.

What it covers

›Large readable gauges
›Packet health summary
›Status ticker
›Ops-room display mode

Operator notes

$Use NOC Mode on a wall display during major changes.
$Watch trends instead of single samples.
$Pair with external provider status before declaring root cause.
