Deduplication
GlossaryWritten by Burak YReviewed by Burak YLast reviewed 3 September 2026
Combining repeated alerts that represent the same underlying condition. Deduplication is normally driven by a key derived from the alert itself, so that a condition firing every thirty seconds produces one incident rather than a hundred notifications. It reduces interruption without hiding the condition, which is what separates it from suppression.
In practice
Five application instances all report the same failing downstream dependency. A dedup key based on the dependency, not the instance, turns five pages into one incident with five occurrences.
