Alert (or alarm) fatigue, also known as overload, is a real problem for developers and operations people who support always-on services.
Maybe, if you are lucky enough, you don’t know what it means. So, let’s start with the definition.
Alert fatigue is what happens to your team when they frequently receive an overwhelming number of alerts. If every week or so, you get a lot of alerts for one incident, that is not alert fatigue. It has to happen frequently.
Alert fatigue is a big concern for services and for those who are responsible for them. One study showed that for every reminder of the same alert, the attention of the alerted person dropped by 30%.
