# Metric anomaly
A {doctitle} is a situation in which a [metric](https://docs.coveo.com/en/263/) is out of its usual trend for at least one full hour.
An anomaly isn't just a small deviation or variation, but something truly out of the usual.

**Example**

After a new application deployment, the daily number of events suddenly drops to be significantly lower than on previous days.
