Alert fatigue: when every alert means none of them matter
The alert that matters most — the checkout is broken — usually arrives in the same channel as a hundred that do not. After a few weeks of noise, people stop looking. That is how a real outage waits until morning.
Where the noise comes from
Alerts on CPU spikes, slow pages, single failed requests and warnings from every plugin all compete for attention. Most resolve on their own, so the team learns, reasonably, that alerts can wait.
Flaky checks make it worse. An alert that fires and clears three times a week because of a slow test environment teaches everyone that a red alert is probably nothing.
What a good checkout alert looks like
It fires only when a real customer would fail: the order could not be placed. It confirms the failure before paging — a second run, not a single blip — so a person trusts it when it arrives.
It says what broke and where: the step, the error, a screenshot. “Checkout failed at payment: widget did not load” gets acted on. “Check failed” gets snoozed.
Route it on purpose
Send the checkout alert to a person, not only to a shared channel, and to somewhere they will see it out of hours. Keep lower-priority notices in a separate place so they do not drown it.
Review every alert that fired last month. If nobody acted on it, lower it, merge it or delete it. The goal is a short list where each alert means someone should stop what they are doing. Related: how MageSentinel groups failures into incidents and the first hour after an alert.

Common questions
What is alert fatigue?
Too many alerts that turn out to be nothing, so people start ignoring them, including the real ones.
How do I reduce false alerts?
Confirm a failure with a second run before alerting, alert on incidents rather than every failed run, and fix flaky checks.
What should a checkout alert contain?
Which store, which step failed, since when, and evidence such as a screenshot, so the reader can act without logging in.
