If things go wrong, many events may be sent to marbot, resulting in similar alerts. To avoid a flood of alerts, marbot groups similar events into one alert (deduplication). marbot will keep you updated about the number of events aggregated into one alert.
By default, alerts are grouped for seven days and notifications for one minute. If you close an alert, the aggregation starts again as well.
Alert aggregation in Slack:
You can configure the window size for both alerts and notifications. Send a message in a channel mentioning @marbot:
@marbot Configure this endpoint!
