Proactive alerting of issues is important, but having too many alerts can be overwhelming. The latter can cause alert fatigue, and this is usually the result of not being able to correlate related alerts (or events) into a single issue that can be managed holistically.
Event Compression Policies in Enterprise Manager address this need. It automatically correlates and compresses related events into a single, actionable incident. The overall result of compression is a smaller set of meaningful incidents that ITOps teams can manage. This feature is available in Enterprise Manager 13.5 Release Update 8 (RU8) and later versions.
