After trying to close some old APM (SaaS) alarms manually, they do not appear to get closed on the OI side as expected. How does it work?
The old alarms are now controlled by the "Auto-Purge" feature and it has been documented in our guides, refer to "Configure the Data Purge":
NOTE: if you need to automate this task open a support ticket, provide reference #DE482623
