Reducing alert noise involves drawing a line between incidents that need an immediate response and ones that do not. Get this distinction wrong and your team is either interrupted unnecessarily or misses something critical. In this guide, we’ll help you make that distinction clear. We’ll cover what counts as noise and how to reduce it without missing what matters.

Alert fatigue doesn’t announce itself. It builds quietly over weeks and months until one day a critical incident triggers and nobody responds with the urgency it deserves. By that point, the damage is already done. This guide walks through what alert fatigue actually is, how it happens, and what you can do about it.

When you launch a new service in production, you’re working with a lot of unknowns. You don’t yet know how it behaves under real traffic or which incidents are worth waking someone up for. That makes alerting for a new service a little different from what you’re used to with an established one. The goal in the early days isn’t to get everything perfectly configured. It’s to learn enough about the service to get your alerting right.

Not every incident alert needs the same kind of response. One incident may need to wake someone up right away. Another may simply need to be picked up when the team starts work in the morning. Without a clear way to tell them apart, every incident feels equally urgent. That usually adds noise and makes incident response decisions harder than they need to be. This is where two questions help: In this guide, we’ll discuss what those questions mean and the four combinations that follow.

Monitoring tools track what’s happening across your systems and send a Slack message or email when something looks off. But they don’t call anyone and they don’t escalate the incident. If that Slack message goes unseen at 3 AM on a Saturday, the incident just sits there until someone opens their dashboard. Incident alerting fills this gap. When an incident triggers, it contacts the right person directly through a phone call or their preferred channel.

Critical incidents have a direct impact on your business revenue and the trust your customers place in you. The longer a critical incident goes unnoticed, the higher the stakes. A reliable alert routing setup automatically catches these incidents the moment they trigger and gets them to the right person without delay. This guide walks you through how to build that reliable routing setup.

When a midnight incident triggers, the goal is not to wake your entire team. It’s to reach the one person who can act on it. Everyone else should sleep through it undisturbed. The difference between a team that handles midnight incidents well and one that doesn’t usually comes down to a few decisions made ahead of time. Which incidents actually need a midnight response? Who should get the call? And what should happen to everything else? This guide walks through those decisions.

Severity and priority are two labels that describe different things about an incident. Severity covers the blast radius: how much of your system or how many customers are affected. Priority covers the urgency: how quickly someone needs to act. Routing rules then use these labels to load the right escalation policy for each incident. This guide covers how to define your severity and priority levels and map them to escalation policies.

Every incident arrives with a payload, and that payload usually tells you far more than whether something broke. It points to which service is affected and how serious the issue looks. It also carries context about which customers are on the receiving end of that failure. The service name, severity, customer context — all of it can feed directly into routing decisions. This guide explores how to read those parts of the payload and use them to route incidents automatically.

When an incident triggers, the question is not just what broke but also how urgent it is and who on your team needs to respond. Alert Routing rules answer those questions automatically. You define the conditions once and the right response follows every time an incident triggers. Every Alert Routing rule does one or more of these three things: Three conditions drive all of it: incident payload, time of occurrence, and frequency.
