What we want is an automated downtime adapter/integration/something else which sends the affected ci's to OpsBridge for Downtime management. Example:
Change xxxx --> Execution date 1/1/2020 19:00 till 1/1/2020 21:00
Affected ci's: Business application X
Server X etc.
In the change you can choose for an option to send the ci's to Opsbridge. Something like "Automated Downtime? yes / no." when chosen for Yes the ci's will be send to OpsBridge and they will be in Downtime from 1/1/2020 19:00 till 1/1/2020 21:00.
Why would you need something like this? Because now you don't have to worry about critical events / incidents which are created by the monitoring in the timeframe of your change.
