Is it possible to only notify team members on the first alert (or first couple of alerts) that are received by an OpsGenie integration within a given time period? For example, when we have a physical site go down, 20+ alerts may be generated by our monitoring system within a 5 minute period due to various devices at that site becoming unreachable. We only wish to notify team members of the first alert that occurs during that 5 minute period to prevent them from being flooded with notifications at the start of a site outage. It appears that PagerDuty has a feature called "Time-Based Alert Grouping" that provides this type of functionality. Is there a way to accomplish this type of functionality in OpsGenie?
I have already looked into OpsGenie's deduplication options that involve modifying the alias on incoming alerts in order to automatically group them into one alert. However, that's not quite what I'm looking for. I still want all of the unique alerts to be displayed in OpsGenie and available for acknowledgement as this helps give a technician a sense for the scope of the outage. But a technician only needs to receive an alert for the first (or first couple of alerts) that come into OpsGenie to know that an issue is occurring and needs attention.
Thanks for any help someone can provide here!
