What is a blind spot?

A part of your system that no working alert covers, so a failure there raises no alert. A service with no alert, a muted alert, or an alert that notifies no one are common ones.

Does Noci AI switch on alerts by itself?

Noci AI proposes the alert. Setting it up is your decision.

What does triage have to do with blind spots?

Noisy alerts are how coverage shrinks. When people drown in noise they mute and delete alerts. Triage scores each alert and shows the reasons, so the noise is handled and the alerts that matter can stay on.

Is there a way to look for blind spots by hand?

Yes. A coverage review by service, a synthetic check on each important journey, and a standing question at every incident review about who noticed first. The guide on detection time covers them.

Blind spots: find what no alert covers

Blind spots are the services and resources that no working alert covers, and a customer is often the first to find one. Noci AI names what is unwatched and proposes the alert that would cover it. Triage takes the noise off your team, so alerts stay switched on instead of being muted.

Blind spots are the silent killers of a production system: a failure nobody is alerted to. It pages no one and shows on no dashboard. Often a customer finds it first, which is the worst way to find out. It is not bad luck: it grows out of alert fatigue.

The loop is a common one.

Alerts are noisy. The pager goes off for things that need no action, and people stop trusting it.
Teams mute and delete alerts. It is the only way to get some quiet.
Coverage shrinks. Nobody decides to stop watching a service. The alert that watched it is simply gone.
The next outage arrives unannounced. A customer finds it before anyone on call does.
More alerts are added. The fix is to cover everything, and the noise comes back.

Then it starts again from the first step. Adding alerts alone never ends it, and neither does muting them.

How does Noci AI break the loop?

From both ends.

It takes the noise. Triage reads every alert as it arrives, scores its noise and shows the reasons, so people keep alerts switched on instead of muting them. See AI SRE.
It finds what is unwatched. Noci AI looks for the services and resources that no alert covers, and proposes the alert that would cover each one.

With the noise handled, nobody has a reason to cut coverage. With the unwatched parts found, the gaps are named so you can close them.

What do you decide?

You choose which proposed alerts to set up. Noci AI shows what is not covered and what the alert would watch, and your team decides what belongs on the pager.
